zerobyte releases

⚠️ Action required

• Outbound webhook destinations now require an allowlist: Webhook calls must target origins listed in the new WEBHOOK_ALLOWED_ORIGINS environment variable.
  • This applies only to Generic Webhook, Gotify, self-hosted ntfy servers, and Custom Shoutrrr URLs
  • Example: WEBHOOK_ALLOWED_ORIGINS=https://hooks.example.com,http://host.docker.internal:8080

After updating your instance, test your notifications!

New features

• Pre and post-backup webhooks: Backup schedules can now run optional webhook calls before and after a backup. This enables integrations such as waking external systems, triggering automation, or notifying other services around backup execution. Check out the new backup webhooks documentation
• Notification delivery health is now visible: Notification destinations now track and display health status, last check time, and last delivery error, making notification problems easier to diagnose.

Improvements

• Sortable tables: Repositories, volumes, and notifications can now be sorted by table columns, making large setups easier to browse and manage.
• Improved backups for FUSE-like volumes: Backups for rclone, SFTP, and WebDAV volumes now default to Restic’s --ignore-inode behavior when needed, reducing false file-change detection issues
• Bump rclone to 1.74.0

Bug fixes

• Fixed SMTP notifications with special characters in credentials: Email notification passwords and usernames containing special characters are now encoded correctly.

New features

• Mirror repositories can now be backfilled from the UI by reviewing missing snapshots and syncing only the ones you choose. This is especially useful when adding a mirror to an existing backup schedule. Thanks @eric-hess for the implementation

Improvements

• New documentation site: Zerobyte now has a dedicated docs website at zerobyte.app

Bug fixes

• Backups now verify volume health before starting: If a volume has gone stale or become unreachable, Zerobyte now fails fast or remounts first when auto-remount is enabled

We now have a Discord server

New features

• Automatic backup retries: scheduled backups now retry after failures with configurable retry count and delay. Thanks @Der-Penz
  for the implementation
• Zerobyte can now read APP_SECRET from APP_SECRET_FILE, which is useful for Docker and Kubernetes secret-based setups.

Bug fixes

• Snapshot loading is more reliable on large repositories: repositories with large snapshot lists no longer fail because of command output buffer limits
• Slack webhook channel overrides are no longer configurable since it is not supported initially by Slack
• Rclone remotes are now correctly detected when using a custom RCLONE_CONFIG_DIR
• SMB-backed volumes now handle UTF-8 filename encoding more reliably, reducing backup failures on shares with special characters in file names.

• Dedicated edit pages for backups, volumes, and notifications with redesign for consistent UX across all the pages.
• Fix language detection bug when the browser sends multiple locales with quality param
• Fix mirror copy concurrency causing dead locks
• Fixed snapshot browsing for snapshots created from Windows or other non-POSIX paths.
