Backups and restore

Backups contain the Élise database. They are encrypted: by default Élise refuses to create a plaintext backup.

Set up encryption

Section titled “Set up encryption”

Élise uses age. Generate a key pair on your computer, not on the hub:

Fenêtre de terminal
age-keygen -o elise-backup.key

Keep elise-backup.key somewhere safe, outside the home. Copy the public key (age1…) into /etc/elise/elise.env:

Fenêtre de terminal
MICHEL_BACKUP_RECIPIENT=age1…

Back up

Section titled “Back up”
Fenêtre de terminal
elise backup

Archives are written to /var/lib/elise/backups/. Copy them off the hub regularly.

Restore

Section titled “Restore”
Fenêtre de terminal
elise restore /var/lib/elise/backups/elise-YYYY.tar.age --confirm

A restore overwrites changes made after the backup. Test your procedure on an isolated instance before relying on it.

What is not backed up

Section titled “What is not backed up”

Camera alert images are excluded from backups and deleted after 24 hours.
