I’m going to make a backup of 2TB SSD today. I will use clonezilla mainly because that’s all I know. But do you recommend any other ways for any reason?
I want to keep the process simple and easy. And I will likely take backup once a month or so repeatedly. It doesn’t have to be ready all the time. If you need more clarification, ask away.
RAID is not a backup, no. It’s redundancy. It’ll keep your service up and running in the case of a disk failure and allow you to swap in a new disk with no data loss. I don’t know how Immich works but I would put it in a container and drop a snapshot anytime I were to update it so if it breaks I can just revert.
