Borg Backup Server v1.0.0-RC1

The first release candidate for v1.0.0. This release includes major architectural improvements to S3 offsite sync, a redesigned plugin management UI, and numerous bug fixes.

Highlights

S3 Sync Decoupled from Backup Plans

S3 offsite sync is now tied directly to repositories instead of backup plans. Deleting a backup plan no longer removes your S3 sync configuration or blocks access to offsite restores.

Redesigned Plugin Management

The Plugins tab has been completely rebuilt with a cleaner, more intuitive interface:

• Full-width plugin cards with inline enable/disable toggles
• Configuration forms expand inline when a plugin is enabled
• Condensed form layouts for MySQL and PostgreSQL
• S3 plugin uses radio buttons for Global vs Custom credentials
• S3 configs auto-named "Global Settings" when using global credentials

Server-Side S3 Connection Testing

The S3 "Test" button now runs instantly on the server via rclone, instead of dispatching to the client agent. Results are immediate.

What's New

• S3 sync tied to repositories — new repository_s3_configs table with automatic migration from plan-based configs
• S3 connection test — runs server-side via rclone with instant results
• Plugin tab redesign — cleaner cards, inline config forms, condensed layouts
• S3 auto-naming — "Global Settings" name auto-assigned when using global credentials

Bug Fixes

• Fixed S3 restore (copy mode) failing with missing name key
• Fixed orphan S3 restore failing with same missing name key
• Fixed undefined $taskLabel error on queue detail page
• Added missing server-side task types to queue view (s3_restore, catalog_sync, catalog_rebuild)
• Prevented duplicate S3 sync and prune jobs from being queued

Updated Plugin Descriptions

• MySQL: "Dumps MySQL databases before each backup, storing them in the repository for easy one-click restore back to the server."
• PostgreSQL: "Dumps PostgreSQL databases before each backup, storing them in the repository for easy one-click restore back to the server."
• S3: "Automatic sync of repositories to any S3-compatible storage after backup and prune operations. Stores a manifest for fast restore without long borg operations."
