v4.2.3

These are unofficial binary packages of Proxmox Backup Server 4.x for ARM64.

Official Changelog

rust-proxmox-backup (4.2.3-1) trixie; urgency=medium

• css: remove x-grid-row-loading class, replace it with non-blurry SVG
  variant from proxmox-widget-toolkit

• pbs-client: add backoff log throttle, to ensure progress and similar output
  appears quickly initially, but does not create overly long logs

• client: report progress during restore

• api: journal: adopt proxmox-syslog-api and stream the output, making the
  implementation consistent with the one from Proxmox Datacenter Manager

• ui: enable the structured journal view and per-service logs, including
  colored output and filtering capabilities

• ui: always use arrays for 'delete' property, instead of manually converting

• fix #5971: tape: don't warn on custom MAM attribute write failures

• fix #7175: api: time: use timedatectl instead of /etc/timezone

• fix #7187: report: add ethtool output for physical interfaces

• prune jobs: schedule jobs that do not prune anything, but warn during their
  execution. such jobs allow testing scheduling options, but make no sense
  for production use.

• fix #6691: allow search by comment in datastore content, make search
  case-insensitive and correctly reset content view after empty searches

• ui: datastore: disable various action tooltips for actions which cannot be
  triggered

• ldap: escape the user-provided user name when using it in the LDAP search
  filter that looks up the user DN.

• ldap sync: log which user properties change when synchronizing an existing
  user, instead of only reporting that the user was updated.

• api schema/section config: add support for declaring deprecated property
  aliases, to allow renaming properties without showing the old name in the
  documentation

• rest server: accept deprecated property aliases in JSON request bodies by
  rewriting them to the canonical name before verification and dispatch, like
  the CLI and query-string handling already do.

• fix #7690: fs: replace_file: close the temporary file before renaming or
  unlinking it, fixing the replacement on WORM file systems and avoiding
  leftover .fuse_hidden files on FUSE mounts.

• fs: make_tmp_file: append the temporary suffix instead of replacing the
  file extension, keeping the original file name intact for easier
  debugging of leftover temporary files.

v4.2.2

These are unofficial binary packages of Proxmox Backup Server 4.x for ARM64.

Official Changelog

rust-proxmox-backup (4.2.2-1) trixie; urgency=medium

• api: backup: run synchronous chunk-insert operations off the asynchronous
  runtime's worker threads. Blocking those threads, most notably during S3
  uploads that can wait up to three hours for a chunk lock, could stall the
  I/O and timer drivers of the entire runtime and starve other backup
  workers.

• client: backup: make the file-based backup more robust against files that
  cannot be accessed or that vanish while the backup is running:

  • fix #7658: skip a file and log a warning instead of aborting the whole
    backup when querying its metadata fails with a permission error,
    matching the existing handling of permission errors when opening files.
    Such files can also still be excluded explicitly.
  • consistently ignore files that disappear during the backup and warn
    about them, instead of treating this as a fatal error in some cases.

• tape: backup: fix the command-line group filter, which was passed to the
  API under the wrong parameter name and thus had no effect.

• api: do not log a spurious error when listing the files of a snapshot
  whose manifest does not exist yet, which is expected while a backup to
  that snapshot is still running.

• ui: datastore summary: fix the per-datastore sync and prune job counts,
  which were derived from an incorrectly parsed datastore ID; the prune
  count in particular was always shown as zero.

• tape: fix two typos in log and informational messages.

v4.2.1

These are unofficial binary packages of Proxmox Backup Server 4.x for ARM64.

Official Changelog

rust-proxmox-backup (4.2.1-1) trixie; urgency=medium

• fix #5076: api: support an 'audiences' property on OpenID realms, listing
  additional trusted audience values besides the configured client-id.
  Improves compatibility with providers that issue tokens with multiple
  audiences.

• fix #7562: api/ui: tape: separate the format-media 'load-barcode'
  parameter from the existing 'label-text' verification, so the web
  interface can load and format empty or previously-unrelated tapes from a
  changer slot in one step. The old shared parameter aborted formatting
  after a successful load whenever the on-tape label did not match.

• sync: pull: refuse to overwrite a locally encrypted snapshot from an
  unencrypted source or one using a different key, and detect content
  differences between two unencrypted snapshots that share a backup time.
  Previously such mismatches silently triggered a resync that overwrote the
  local snapshot.

• datastore: fix tuning option changes not propagating the updated sync
  level to the chunk store until the service was restarted.

• datastore: improve the error message when prune cannot acquire a snapshot
  lock for deletion, by showing the snapshot directory and lock file paths
  instead of an internal debug dump.

• api: backup: fix benchmark, finish-failed, and backup-failed cleanups
  leaving an orphaned empty backup group behind on the datastore.

• api: node: tasks status: return the task end time as an optional field
  once the task is finished, so the task viewer can render the correct
  duration without an extra API call.

• api/ui: node: add a 'location' property to the node config, exposed
  through the node options panel.

• subscription: reuse the server ID from an existing subscription info when
  multiple candidates are detected, falling back to the first candidate only
  when no prior info exists.

• chunk store: include the filesystem backing path in the syncfs log output
  for easier identification of which directory is being synced.

• tree-wide: print error chains as a colon-separated single line and stop
  quoting simple errors without context, making logs and CLI output easier
  to read at a glance.

• ui: encryption keys: extract the error message from API2 responses before
  displaying the alert, so permission and other endpoint errors no longer
  surface as an empty popup.

• removable device attach service: clarify the systemd unit description so
  it no longer suggests that mount is attempted for every device or that
  every device is a datastore.

• docs: faq: correct the Debian Bookworm end-of-life date; the last point
  release is planned for July 2026.
