Maintenance and backups
Scheduled disk checks
Section titled “Scheduled disk checks”Storage > Maintenance schedules SMART short and extended self-tests and RAID consistency checks. A systemd timer runs them even when the dashboard is down.
- A check whose time slot was missed (server off or asleep) runs at the next hourly tick.
- Sleeping disks are not woken up, and no check starts while an array rebuilds: the check is retried every hour, and the page says why it did not run.
- Each disk’s self-test shows as Running (with what is left), then Passed or Failed. Disks that cannot run SMART self-tests are listed as skipped.
- A RAID mismatch raises an alert.
Configuration backup
Section titled “Configuration backup”Settings > Backup & restore exports the HSI configuration, encrypted with AES-256-GCM and a password-derived key: the database, the account ids, the app definitions and the volume descriptions. A restore shows a preview first and stops on account id conflicts. Files in Places and Docker volume contents are not part of it. See Backup and restore the configuration.
Data backups
Section titled “Data backups”The Backups page runs two kinds of plans, each from its own systemd timer, so they run even when the HSI server is down:
- Sync plans copy a folder with rsync, locally or over SSH, as a mirror.
- Versions plans take encrypted snapshots with restic into a repository (a folder, an SFTP server, S3-compatible storage or a restic REST server), keep the history you choose and let you restore a file or a folder from any snapshot.
A failed run or a failed repository check raises an alert. See Backups of your data.
