I’m trying to figure out how to configure Immich in the optimal way.

I have a Synology RS812 with 512MB of RAM so not enough to run Docker and Immich, but it has 10.7TBs of storage in SHR1.

I also have a VM farm with 256GBs of RAM and 3TB of usable storage with no RAID.

My initial thought was to host Immich on my VM farm (obviously) and store all the photos on the Synology. Then load the photos as an external library from the Synology. This works, but it means I need to set up an automatic upload to the Synology directory.

The second idea is to give Immich the 3TB on VM Farm, have it store photos locally, and then using Rsync to copy photos over to the Synology automatically. The concern here is if Rsync fails I might not notice for a while which runs the risk of data loss.

How would you configure this?
