Retention and cleanup¶
Database retention¶
| Setting / env | Default | Effect |
|---|---|---|
History retention days / DATABASE_HISTORY_RETENTION_DAYS |
90 | Prune SAB history rows; does not delete WebDAV mounts |
Health-check retention / DATABASE_HEALTHCHECK_RETENTION_DAYS |
30 | Prune health result rows |
DATABASE_MAINTENANCE_INTERVAL_HOURS |
6 | Sweep cadence (env) |
Configure in Settings → Maintenance.
NZB blobs¶
Blobs under {CONFIG_PATH}/blobs/ remain while referenced by queue, history, or mounted /content. When the last reference drops, background cleanup removes them. History retention alone does not make mounts eligible for orphan deletion.
Orphaned files¶
Remove Orphaned Files (Maintenance) deletes WebDAV files not linked from the library directory. Supports dry run. Schedule optional daily cleanup — set container TZ.
NZB file backups¶
Optional copies of incoming NZBs (SABnzbd settings) prune by api.nzb-backup-retention-days.
