Tools and ideas for backup of many files (feddit.nl)

Hello everyone,

In a day or two, I am getting a motherboard with an N100 integrated CPU as a replacement to the Raspberry Pi 4 (2 GB Model). I want to run Jellyfin, the *arr stack and Immich on it. However, I have a lot of photos(for Immich) and movies(for Jellyfin) (in total about 400 GB) that I want to back up, just in case something happens. I have two 1TB drives, one will have the original files, and the second will be my boot drive and have the backup files.

How can I do that? Just copy the files? Do I need to compress them first? What tools do I need to use, and how would you do it?

Thanks in advance.

EDIT: I forgot to mention that I would prefer the backups to be local.

Thanks for responding. I actually don't have Immich yet on the Raspberry Pi, so it's the first time I will be installing it and then importing the photos. I don't actually care a lot about the migration, since I can just reconfigure the services. I want to ensure that if a drive fails, I can restore the data. I would try RAID, but I read that "RAID is not backup". Or I could just run the command you provided in a cronjob.

In that case I'd recommen you use immich-go to upload them and still backup only immich instead of your original folder, since if something happens to your immich library you'd have to manually recreate it because immich doesn't update its db from the file system.
There was a discussion in github about worries of data being compressed in immich, but it was clarified the uploaded files are saved as they are and only copies are modified, so you can safely backup its library.

I'm not familiar with RAID, but yeah, I've also read its mostly about up time.

I'd also recommend you look at restic and duplocati.
Both are backup tools, restic is a CLI and duplocati is a service with an ui.
So if you want to create the crons go for restic.
Tho if you want to be able to read your backups manually maybe check how the data is stored, because I'm using duplicati and it saves it in files that need to be read by duplicati, I'm not sure if I could go and easily open them unlike the data copied with rsync.
