• Short: It is a second Hardrive using borg that backs up the primary harddrive.

• Long: My Backup strategy:-

Databases and other imp files:

For databases the backup happens every night that gets saved on the server itself. Then when my laptop connects either to the home network or to the Internet, the backup zip files on my server syncs to my laptop via syncthing. Then my laptop’s data is backed up to OneDrive (encrypted) — this includes the immich database backups. I usually keep 7 days worth of backup files just incase some get corrupted and I can just go back to the previous day.

Library

Since my Immich Library is big, daily borg backups are not possible for 200 gigs. So I have scheduled them every Sunday morning when I rarely use the server. The photos gets uploaded to the hardrive mounted to Immich’s Library directory. The hard drive is exclusively used only for Immich. That hard drive is then backed up to another hard drive using borg and also to my OneDrive using rclone. (All encrypted). So 3 copies of the data, 2 on 2 different hardives (off which 1 is primary) and one offsite.
