How Do You Handle Immich and Backup Separately?

How is your Immich setup? My images are currently stored on external SSDs as backups. Since those are just for backup, I assume I need a different storage solution that stays connected to the server for Immich to work properly.

How do you manage this? Do you keep a separate backup alongside Immich, or do you integrate both in some way? It seems like these are two different things—one for safe storage and one for online access. Curious to hear how others handle it!
