Backup solutions (feddit.de)

Hands down, I'm way too late to the party with my backup-strategy, and I have no good explanation.

I have a NAS with OMV on it, and I'm in dire need to create an offsite-backup. I have an old Synology DS215j, which I'd be able to put into my parents home (hundreds of kilometers away).

I didn't find the energy to research the ways of doing what I want to do. As those are two different systems, the task seems enormous to me, without knowing what to do.

I imagined, that the Synology spins up once a day/once a week, and syncs the data and appdata (two different folder-structures on my NAS), with a certain number of snapshots.

Would you mind helping me a bit, giving me ideas how to set this up? Am I able to prepare this at home, before I bring this to my parents place?

Thank you a ton!

EDIT: Thank you all for your recommendations. I will take the time to read them thoroughly!

I personally do a restic backup on my server (I have a dedicated hetzner server), and keep a backup on the server itself, and do a backup to a backblaze bucket for an offsite backup.

I also have a restic check job run every week, that reads 10% of the random data making sure everything is fine and working correctly.

For my local machine I do the same but additionally backup also to an usb drive for a 3-2-1 backup solution.
