Releases

• Add upload progress bar with real-time percentage and byte counts for backup ZIP uploads

New: Themes & Modules Directory Backup#

You can now include the themes/ and modules/ directories when creating a backup, giving you a complete snapshot of your entire Omeka S installation in a single archive.

What's new#

• Two new checkboxes on the Create Backup page: Include themes directory and Include modules directory (both enabled by default)
• Corresponding restore options appear automatically when restoring a backup that contains these directories
• Dry-run restore preview now lists themes and modules overwrite actions alongside the existing database and files warnings
• Auto-detection for uploaded/imported backups — if a ZIP contains themes/ or modules/ folders, they're recognized and offered for restore

Upgrade notes#

• No database migration required
• Existing backups remain fully compatible — they simply won't show themes/modules restore options since those directories aren't present in the archive
• Be aware that including modules may significantly increase backup size depending on the number of installed modules

Full system backup and restore for Omeka S. Creates ZIP archives containing a MySQL database dump, uploaded files, and a JSON-LD API export of all resources. The database dump is pure PHP via DBAL — no mysqldump binary required.

Features:

• Create backups via the admin UI or a CLI script (bin/backup.php) suitable for cron jobs
• Selectively include/exclude database, files, and API export per backup
• Restore from any backup with a dry-run preview and a "type RESTORE to confirm" safeguard
• Upload an existing backup ZIP to restore on a different installation
• Configurable backup directory and retention policy (keep last N backups)
• SHA-256 checksum verification before restore
• Background jobs for both backup and restore operations
• Access restricted to global_admin and site_admin roles
