Navigate to Admin > Backup > Settings.
| Setting | Default | Description |
|---|---|---|
| Backup storage path | OMEKA_PATH/backup |
Absolute filesystem path where ZIP archives are stored. Must be writable by the web server user. |
| Retention: keep last N complete backups | 7 |
Older complete backups are automatically deleted after each new backup. Minimum value: 1. |
Verifying the backup directory
The Settings page displays whether the configured path exists and is writable. Fix any issues before running your first backup.
Protecting backup files from web access
The module writes a blank index.html into the backup directory to prevent directory listings on servers with that feature enabled. For stronger protection, place the backup directory outside your web root, or add a .htaccess rule denying direct access.
Cron (automated backups)
The Settings page shows a ready-to-use cron line. It looks like:
0 2 * * * www-data php /var/www/omeka-s/modules/Backup/bin/backup.php create >> /var/log/omeka-backup.log 2>&1
Run this as the web server user (www-data or apache) at a time when traffic is low.
