Proxmox Backup Server 2.4

Released 29. March 2023

  • Based on Debian Bullseye (11.6)
  • Latest 5.15.102 Kernel as stable default
  • Newer 6.2.6 kernel as opt-in
  • ZFS 2.1.9

Highlights

  • Proxmox Backup Server now provides a dark theme for the web interface & the documentation.
  • Add LDAP as a new user authentication realm.
  • Add initial support for WORM (write once, read many) tapes.

Changelog Overview

Enhancements in the web interface (GUI)

  • Add a fully-integrated "Proxmox Dark" theme variant of the long-time Crisp light theme.
By default, the prefers-color-scheme media query from the Browser/OS will be used to decide the default color scheme.
Users can override the theme via a newly added Color Theme menu in the user menu.
  • Task logs can now be downloaded directly as text files for further inspection.
  • The Add User dialog has now a realm field, making it possible to add users to an LDAP or OpenID Connect realm manually.
  • Improve the UI for verification jobs, showing the namespace and max-depth columns and allowing one to edit those fields in the edit job window (#4448).
While the API supported limiting a verification job to a specific namespace or depth since 2.2, such settings weren't editable nor visible in the web interface.
  • The 'Services' panel of the 'Administration' section now marks optional services that are not installed as not installed instead of marking them as dead.
  • In order to make it more obvious how to disable scheduled Garbage Collection (GC), the 'GC Schedule' window now shows an X button that resets the schedule to none.
  • For prune jobs, rename 'Store' to 'Datastore' for consistency reasons.
  • Fixed the default value for pruning mail notification settings in the datastore options.
  • Fixed rendering the 'Enabled' column for the 'Metric Server' view.
  • Improved translations, among others:
    • Arabic
    • French
    • German
    • Italian
    • Japanese
    • Russian
    • Slovenian
    • Simplified Chinese
    • Traditional Chinese

General Backend Improvements

  • Add LDAP realm authentication and user synchronization
This allows user authentication against an external LDAP server. In order to be able to log in, users in LDAP realms must be added manually. Alternatively, users can be synced automatically from the LDAP server.

Client Improvements

  • Suppress harmless but confusing "storing login ticket failed" errors when backing up to Proxmox Backup Server.
  • The proxmox-backup-manager CLI tool can now be used to trigger an existing prune, verification, or sync job manually.
  • The output of the proxmox-backup-debug diff archive command was improved.
The command now shows file attributes, highlights changes and has colored output.
  • Provide higher runtime control for logging in the pxar CLI tool (#4578).
Users can now decide themselves which messages, log sources or log levels are interesting for a particular use case through the PBS_LOG environment variable.
  • Various improvements for error handling and reported messages to improve user experience.

Tape backup

  • Add initial support for WORM (write once, read many) tapes
  • Skip unassigned tapes when updating the inventory
Tapes that are assigned to a pool but not yet in a media set belong to the special all-zero media set. Since there will never be a catalog on these tapes, trying to restore a catalog will always fail, so leave them out.

Installation ISO

  • the version of BusyBox shipped with the ISO was updated to version 1.36.0.
  • The EFI System Partition (ESP) defaults to 1 GiB of size if the root disk partition (hdsize) is bigger than 100 GB.
  • UTC can now be selected as timezone during installation.

Documentation

  • Expand the documentation for maintenance, focusing specifically on Garbage Collection (GC).
  • Link screenshots in the documentation to their image files.
  • Implement dark mode that honors the prefers-color-scheme media query automatically.
  • Add dark mode support to the API viewer widget.

Notable bug fixes

  • Don't interrupt tasks when pressing Ctrl + C when viewing task logs via proxmox-backup-manager task log or proxmox-backup-client task log (#4483).
  • proxmox-backup-client now prints task logs to stdout instead of stderr (#4387).
  • Removal of all associated prune jobs and ACL entries when their data store is deleted (#4256).
  • Fixed a bug where snapshots were not listed in a tape media set (#4466).
  • Warn if a login ticket could not be stored (e.g. due to $XDG_RUNTIME_DIR not being set, which can happen if invoked via sudo) (#4346).
  • Reduce lock contention of the verify-after-complete feature with periodic syncs (#4523).

Known Issues & Breaking Changes

None.

Proxmox Backup Server 2.3

Released 29. November 2022

  • Based on Debian Bullseye (11.5)
  • Latest 5.15 Kernel as stable default (5.15.74)
  • Newer 5.19 Kernel as opt-in
  • ZFS 2.1.6

Changelog Overview

  • Enhancements in the Web Interface (GUI):
    • Datastore permissions: Allow editing the ACL path and query the available namespaces and add them as ACL path to the pre-defined selections for convenience
    • Datastore content: Only mask the inner view of the content tree on error, to allow a user to trigger a manual reload using the reload button in the top bar
    • Improve navigating the whole Proxmox Backup Server web UI when a user only has limited permissions on a specific (sub-)namespace
    • Show block device partition tree on the web UI
    • Improve the prune-simulator, among other things allow setting a custom simulation "now" date/time
    • Improved certificate view - for example for certificates with many SANs
    • Improved translations, among others:
      • Arabic
      • Dutch
      • German
      • Italian
      • Polish
      • Traditional Chinese
      • Turkish
  • Add Namespace Aware Prune Jobs
    • Expand the single-schedule per datastore to a flexible, namespace aware prune job system
    • Allow fine-grained control over when and how deep a specific namespace get pruned
    • In addition to above, the manual prune action also became more powerful w.r.t. namespace and prune-depth selection
    • Implement email notifications for prune jobs
    • Rework the task log outputs for prune job workers
  • Native Support for Sending Periodic Metrics to InfluxDB
    • Support for HTTP(S) and UDP endpoints
    • Optionally TLS certificate validation can be disabled for HTTPS endpoints
    • Metric data is aligned as good as possible to the stats sent from a Proxmox VE node.
    • Metrics include:
      • CPU load averages, IOwait
      • Memory used/total, Swap used/total
      • NIC traffic statistics
      • Filesystem usage for datastores
      • Blockdevice IOPS and bytes read/written for datastores
  • Support Proxmox Offline Mirroring & Subscription Handling
    • Proxmox Offline Mirror: The tool supports subscriptions and repository mirrors for air-gapped systems. Newly added proxmox-offline-mirror utility can now be used to keep Proxmox Backup Server hosts, without access to the public internet up-to-date and running with a valid subscription.
  • Tape Backup Improvements
    • Improve behavior for vanishing snapshots, only log the event but do not fail the tasks
    • Make total/throughput reporting use human-readable units on tape restore
    • Include used tapes in job notification e-mails
    • Optionally try to restore missing catalogs during inventory
    In a disaster recovery case, in addition to re-inventorizing the labels and media-sets, trying to recover the catalogs from the tape, so that one knows what's actually on them, helps in getting an overview.
  • General Client Improvements
    • Proxmox-backup-client: Added ignore-acls, ignore-xattrs, ignore-ownership, ignore-permissions and overwrite parameters to the restore command: If any of the ignore parameters is set the corresponding metadata is not restored - e.g. there is no chown call if ignore-ownership is set. The overwrite parameter causes the restore to overwrite a file if it is already present instead of failing.
    • File-restore: Add 'format' and 'zstd' parameters to 'extract' CLI command.
    • Add the diff sub-command to proxmox-backup-debug, allowing one to compare pxar archives for two arbitrary snapshots, outputting a list of added/modified/deleted files.
    • Support http proxies through the ALL_PROXY environment variable for proxmox-backup-client. Note that using a general tunnel for all traffic, for example wireguard to shield traffic is preferred.
    • Fix an issue with the mount subcommand, where reading large files could yield corrupt data.
  • General Backend Improvements
    • New mail-forwarding binary proxmox-mail-forward: It unifies the configuration for sending the system-generated mails to the email address configured for root@pam, with Proxmox VE.
    • Implement sync-level option for datastores, allowing one to configure how backup data is synced to disk to match their respective setup and needs.
    • Improve error handling when removing status files and locks from jobs that were never executed
    • Datastore list and datastore status: Avoid opening datastore and possibly iterating over namespace (for lesser privileged users), but rather use the in-memory ACL tree directly to check if there's access to any namespace below.
    • More robust handling of refreshing datastore states periodically and on config change - previously a lock was dropped, causing inconsistencies between long-running backup jobs and garbage collection tasks
    • Datastore: Swap dirtying the internal datastore cache every 60s by just using the available config digest to detect any changes accurately when they actually happen, reducing periodic IO.
    • Restore-daemon: Make file listing "streaming" for better interactivity on initial response
    • API daemon: startup scheduling tasks faster by improving aligning the trigger-time to the minute boundary
    • SMART: Add raw field, for compatibility with the Proxmox VE API - it contains the same data as value, which for now is kept for backwards compatibility
    • SMART: Don't treat certain non-zero exit codes of smartctl as error (if bit 2 of the exit-code is set the returned data is still parseable) - aligns with the implementation in Proxmox VE
    • Improve file-system compatibility for various edge cases: For example take the reservation for root for EXT4 into consideration
    • ACME/Let's Encrypt: Send emails on certificate renewal failure
    • Optimize filtered snapshot listing
    • Move some blocking parts off to their own (reused) thread to reduce the chance of sometimes blocking the tokio reactor thread handling things like new incoming connections
    • Periodically trigger unparking a tokio thread to ensure all newly incoming requests are handled in a timely manner
    • The proxmox-backup-manager pull subcommand now handles a missing namespace parameter by pulling to the root namespace

Known Issues & Notable Changes

  • The upgrade will check if the owner of the lock file /etc/proxmox-backup/.datastore.lck is backup, and if it is not, it will try to correct the owner.
If the automatic owner correction fails, the update process issues a warning and suggests how to try again manually.
Note that this should only affect some older 1.x installations that had no need for locks outside the privileged API daemon and might have created the file with root as owner.

Proxmox Backup Server 2.2

Released 18. May 2022

  • Based on Debian Bullseye (11.3)
  • Kernel 5.15
  • ZFS 2.1.4

Changelog Overview

  • Enhancements in the web interface (GUI):
    • Add "Group Filter" tab to the "Add" and "Edit" windows of sync and tape-backup jobs
    • Allow configuration of the default language used in the web interface
    • Add Markdown aware panel for recording structured notes, and support multi-line comments in the node configuration file.
    • Hide RRD chart for IO delay, if no `io_ticks` are returned
    • Improved translations, among others:
      • Arabic
      • French
      • German
      • Japan
      • Polish
      • Turkish
  • Datastore Backup Namespaces:
    • Implement backup namespaces for datastores.
    Namespaces allow for the reuse of a single chunk store deduplication domain for multiple sources, while avoiding naming conflicts and enabling more fine-grained access control.
    • Add support for syncing a source namespace into any target namespace.
    With the max-depth setting, you can control how deep the recursion on finding groups to sync should go.
    • Add support for namespaces in current Proxmox VE 7.2, the following versions form the baseline:
    pve-manager >= 7.2-4, libpve-storage-perl >= 7.2-4, pve-container >= 4.2-1, qemu-server >= 7.2-3, pve-qemu-kvm >= 6.2.0-7
  • Maintenance Mode and Active Operations Tracking:
    • Implement read-only and offline maintenance modes for a datastore.
    Track whether each datastore access is a write or read operation, so that Proxmox Backup Server can gracefully enter the respective mode, by allowing conflicting operations that started before the maintenance mode to finish.
    Once enabled, depending on the mode, new reads and/or writes to the datastore are blocked, allowing an administrator to safely execute maintenance tasks, for example, on the underlying storage.
  • General backend improvements:
    • Improve memory footprint
      • Improve interaction with the glibc system allocator to dramatically decrease peak and overall RSS memory usage
      The glibc allocator has a misguided heuristic to detect transient allocations, which will only start to use mmap in allocation sizes above 32 MiB.
      This means that relatively large allocations end up on the heap, where cleanup and returning memory to the OS is harder to do and easier to be blocked by small, long-living allocations at the top (end) of the heap.
      By reducing the threshold for switching from the cached heap to the kernel provided mmap to 128 KiB, we can lower peak RSS usage by a factor of 10, or even 20 in some scenarios.
      See the git commit for more details.
      • Optimize LRU caches
    • Add streaming interfaces for some API endpoints, such as the task-log list or snapshot list.
      This can remove the need to collect large lists into intermediate memory buffers.
    • Transform all access to group or snapshot lists to efficient, lazy iterators.
    • Improve IO access pattern for some scenarios, like TFA with high user and login count.
    • Disable SSL/TLS renegotiation in the API daemon.
    • For zpools created via the API, set the `relatime=on` flag by default.
    • Allow for the disabling of inode-sorting for chunk iteration.
    While inode-sorting benefits read performance on block devices with higher latency (for example, spinning disks), it also requires extra work to get the metadata needed for sorting, so it's a trade-off. For setups that have either very slow or very fast metadata IO, the benefits may turn into a net cost.
    • Add dry-run option for the proxmox-backup-client backup CLI command.
    • Verify: Allow one to enforce verification when manually verifying a datastore or namespace through the web interface
    • Improve reload behavior of the proxmox-backup-proxy API daemon
    Close acceptor for new incoming connections immediately on shutdown to avoid connection resets during the wait for running tasks to finish.
  • Improvements on file restore
    • Add support for zstd-compressed tar archive download, in addition to the existing zip download option.
    The tar archive supports more file types (for example, hard links and device nodes), and zstd allows for fast, efficient, and effective compression.
    • Add language encoding flag (EFS) to files when creating a zip archive, if an entry is valid UTF-8.
    This improves the handling of non-ASCII code point extraction under Windows.
    • Allow up to 25s for the file-restore VM to have scanned all possible filesystems in a backup.
    • Improve IO access in the file-restore-for-block-backup VM's internal driver, and start disk initialization in parallel to staring the API listening task.
    On average the restore-tool should be waiting more compared to the previous 12s "worst" case wait time.
    • Avoid automatically pre-mounting ZFS pools.
    The upfront time-cost can be too large to pay initially, for example, if there are many subvolumes present. Thus, only mount on demand.

Proxmox Backup Server 2.1

Released 23. November 2021

  • Based on Debian Bullseye (11.1)
  • Kernel 5.13
  • ZFS 2.1

Changelog Overview

  • Enhancements in the web interface (GUI):
    • Add traffic control management panel in the web interface.
    • Load and usage graphs now have much higher resolution.
    • Display the next media label for a tape backup job.
    • Improved translations, among others:
      • Arabic
      • Basque
      • Brazilian Portuguese
      • French
      • German
      • Simplified Chinese
      • Traditional Chinese
      • Turkish
  • Enhancements in Backup Management
    • Support flexible traffic-control bandwidth limits:
    Implement a token bucket filter (TBF) for limiting incoming (for example, backup) and outgoing (for example, restore) traffic from a set of networks.
    Limits can be configured such that they get applied only during specific time-frames.
    • Support for protected backups, which will not be pruned and cannot be removed manually, without first removing the protected flag.
    • Support group-filter for sync jobs and tape-backup jobs:
    For such a job, you can specify if you want to process only a specific type (ct, vm, host), a specific group or a regex that matches the group-ID.
    Multiple such filters can be applied per job. They act cumulatively.
  • Enhance existing OpenID Connect (OIDC) support:
    • Add support for configuring an arbitrary username claim.
    • Allow setting the requested scopes for user information requests. The default remains the same (profile and email).
    • The prompt behavior is now unset (previously hard-coded to login) and can be configured to the OIDC specification defined variants or an arbitrary extension.
    • You can now configure Authentication Context Class Reference (ACR) values to be requested on any authentication request.
  • Improved Round Robin Database implementation
    • Uses a journal to avoid data loss;
    • Uses much higher resolution:
      • per-day: 1 min (previously 30 min)
      • per-month: 30 min (previously 12 hours)
      • per-year: 6 h (previously 1 week)
      • per-decade: 1 week (previously none)
    • Stores data for last 10 years;
  • Backend
    • New debugging tool proxmox-backup-debug
    • Improved support for various tape drives and changers

Proxmox Backup Server 2.0

Released 13. July 2021

  • Based on Debian Bullseye (11)
  • Kernel 5.11
  • ZFS 2.0

Changelog Overview

  • Tape Backup:
    • Matured from technology preview to the first stable release
    • Improve restore flexibility, allowing you to select multiple snapshots for one restore job
    • Read chunks sorted by inode on backup, to leverage improved read speed on slow spinning disks with increased sequential access
  • Backend:
    • Support for Single-Sign-On (SSO) with the new OpenID Connect access realm type
      You can integrate external authorization servers, either using existing public services or your own identity and access management solution, for example, Keycloak or LemonLDAP::NG.
    • ACME/Let's Encrypt integration with stand-alone and DNS Plugins, for easy deployment of trusted certificates
    • Improved caching for proxmox-backup-client map
    • Single file-restore support for VMs that use ZFS or LVM internally
    • Support setting an HTTP proxy for package updates and subscription check requests
  • Enhancements in the web interface (GUI):
    • Make dashboard status panel more detailed, showing, among other things, uptime, Kernel version, CPU info and a high level repository status overview.
    • New Repository management panel in the Administration tab shows an in-depth status and a list of all configured repositories.
      Basic repository management, for example, activating or deactivating a repository, is also supported.
    • ACME/Let's Encrypt GUI integration
    • Support setting comments on a backup group
    • Updated ExtJS JavaScript framework to latest GPL release 7.0
    • Improved translations, including:
      • Arabic
      • French
      • German
      • Japanese
      • Polish
      • Turkish
  • Installer:
    • Rework the installer environment to use switch_root instead of chroot, when transitioning from initrd to the actual installer.
      This improves module and firmware loading, and slightly reduces memory usage during installation.
    • Automatically detect HiDPI screens, and increase console font and GUI scaling accordingly. This improves UX for workstations with Proxmox VE (for example, for passthrough).
    • Improve ISO detection:
      • Support ISOs backed by devices using USB Attached SCSI (UAS), which modern USB3 flash drives often do.
      • Linearly increase the delay of subsequent scans for a device with an ISO image, bringing the total check time from 20s to 45s. This allows for the detection of very slow devices, while continuing faster in general.
    • Use zstd compression for the initrd image and the squashfs images.
    • Update to busybox 1.33.1 as the core-utils provider.

Known Issues

  • Network: Due to the updated systemd version, and for most upgrades, the newer kernel version (5.4 to 5.11), some network interfaces might change upon reboot:
    • Some may change their name. For example, due to newly supported functions, a change from enp33s0f0 to enp33s0f0np0 could occur.
      We observed such changes with high-speed Mellanox models.
    • Bridge MAC address selection has changed in Debian Bullseye - it is now generated based on the interface name and the machine-id (5) of the system.
      Note that by default, Proxmox Backup Server does not uses a Linux Bridge for networking, so most setups are unaffected.

Upgrade from 1.1

See Upgrade from 1.1 to 2.x

Proxmox Backup Server 1.1

Released 15. April 2021

  • Based on Debian Buster (10.9)
  • Kernel 5.4.106
  • ZFS 2.0
  • Tape Backup (Technology Preview)
    • Tape technology has stood the test of time, when it comes to highly reliable, economic and flexible long-term storage of large amounts of data. Key advantages being:
      • the inherent offline nature of the stored data - mitigating crypto-locker attacks;
      • the portability of the tapes - making them ideal for off-site archiving;
      • the existence of WORM (write once read many) tapes - a key requirement for compliance with data integrity regulations in certain environments;
      • the low cost per storage unit;
    • Tape backup jobs back up datastores to a media pool, and multiple datastores can be backed up to the same media pool. Choose to write all snapshots of a datastore or only the latest snapshot per group to the media set.
    • Tape restore jobs restore the content of a media set to one or more datastores - this enables operators to restore multiple datastores from a media set, even if the system does not have the free disk space required in a single datastore (potentially multiple 100 TB).
    • Flexible retention policies (e.g., always recycle tapes, never recycle tapes, recycle tapes after a particular calendar event).
    • New user space tape driver written in Rust.
    • Support for tape encryption using the hardware encryption feature of the LTO tape drive.
    • Support for tape autoloaders - by rewriting the mtx tool in Rust (now pmtx), most autoloaders supported by other tape-backup solutions available on Linux will work with Proxmox Backup Server.
    • For stand-alone tape drives without an attached changer, users are notified via e-mail about necessary (load/unload) operations.
    • The configuration of all necessary components, jobs, and schedules can be carried out comfortably via the web interface.
    • The Proxmox LTO Barcode Label Generator, a small web-app, can be used to generate and print barcode labels for the tapes on standard adhesive label sheets. These help to identify the tapes in an autoloader.
  • Two-factor authentication (TFA) for the web interface
    • The web interface can now be configured to use TFA with one or more of the following implementations:
      • Time-base One-Time Password (TOTP), for clients like FreeOTP, Google Authenticator, etc.
      • WebAuthn, a general standard for authentication. This is implemented by various security devices, like hardware keys or by the trusted platform modules (TPM) of a computer or smartphone.
      • Recovery keys for single use (as backup, should you lose your authenticators).
    • The activation and configuration of TFA can be done by the users themselves or by an administrator.
    • TFA is complemented by the existing, token-based authentication for granting automated access to Proxmox Backup Server resources, for example, when configuring a Proxmox Backup Server storage in a Proxmox VE setup.
  • HTTP compression via Content-Encoding
    • Responses from the Proxmox Backup Server API can get quite large, but in general can be compressed well. By adding support for deflate Content-Encoding, bandwidth is saved and response times are improved, especially over bandwidth constricted links.
  • Compression of file-level ZIP archive downloads
    • Downloading a directory from a file-level backup will now produce a compressed ZIP archive, reducing bandwidth and local space required.
  • Notable enhancements and bug fixes
    • Improved handling of POSIX ACL entries on files.
    • Improved hand-over to new process when upgrading the Proxmox Backup Server packages.
    • Use the local filesystem to handle synchronization, in order to avoid issues with locking on remote filesystems (CIFS/NFS).
    • Changed HTTP timeouts to work more robustly, even over high latency and low bandwidth links, which are not uncommon for remote backup sites.
    • Better error-handling during garbage-collection, coping with the case when there's no space left on a datastore filesystem.
    • Improved UX when using a GPG master key.
    • Verification: Sort chunks by their inode to speed-up access on a storage with slow random-IO, for example, spinning disks.

Proxmox Backup Server 1.0

Released 11. November 2020

  • Based on Debian Buster (10.6)
  • Kernel 5.4 LTS
  • ZFS 0.8.4
  • Backup & Restore (core functionality):
    • Deduplication
      Periodic backups produce large amounts of duplicate data. The deduplication layer avoids redundancy and minimizes the used storage space. Deduplication is performed per datastore.
    • Incremental backups
      Changes between backups are typically small. Reading and sending only the delta reduces the storage and network impact of backups.
    • Data Integrity
      The built in SHA-256 checksum algorithm ensures the accuracy and consistency of your backups.
    • Compression
      The ultra-fast Zstandard compression is able to compress several gigabytes of data per second.
    • Encryption
      Backups can be encrypted on the client-side using AES-256 in Galois/Counter mode. This authenticated encryption mode provides very high performance on modern hardware.
    • Verification
      Backups on disk can be verified with the stored SHA-256 checksums to protect against corruption and bitrot. This can be scheduled periodically including regular re-verification.
    • Remote Sync
      It is possible to efficiently synchronize data from remote sites. Only deltas containing new data are transferred. Optimized and tested for high-latency links.
    • Performance
      The whole software stack is written in Rust, to provide high speed and memory efficiency.
    • Open Source
      Proxmox Backup Server is free and open-source software. The source code is licensed under GNU AGPL, v3.
    • And of course - Backups can be restored comfortably!
  • Proxmox VE Integration
    • Support for incremental, deduplicated backups of qemu virtual machines (supporting QEMU dirty bitmaps) and containers.
    • Simply configurable as a Storage Backend on Proxmox VE
    • Granular restore:
      • Mapping for QEMU virtual disks to loop back block devices
      • File-level restore of container backups
    • Current backup state is preserved across migrations inside Proxmox VE
  • Enterprise support
    With the release of version 1.0, support subscriptions for Proxmox Backup Server are available, providing access to the stable Enterprise Repository (recommended for production use) and to technical support from the Proxmox team.
  • Web interface
    Manage Proxmox backups with the integrated, web-based user interface.
    • Start operations from within the views in which they are relevant
    • Widgets in the GUI provide useful popups when you hoover over (e.g., individual states in the task summary, on the dashboard)
    • Improved and mature user experience in the GUI - many features known from other Proxmox products were ported to the new Rust code-base to provide the same level of comfort during daily work:
      • Online reference documentation for the current version, available in the GUI via the Help button
      • System console via xterm.js
      • System updates and changelogs
      • Display of the system's journal
  • Scheduling
    • Management and scheduling of maintenance tasks provides all the settings necessary to just configure it once and not have to think about it
    • Scheduling based on the flexible systemd-time specification
  • E-mail notifications for scheduled background tasks (verification, pruning, garbage collection, sync jobs).
  • Vastly improved user interface
  • Sensible encryption-key handling
    • Proxmox Backup Server encryption keys are stored as simple json files, and can be easily stored off-site for disaster recover purposes
    • They can also be exported as QR-codes for printing on paper and storing off-line
  • Flexible Access Control:
    • Support for fine-grained ACLs for separate users on different objects (datastores, remotes, system configuration)
