Comment on How to store backups?

Don’t use a synchronized folder as a backup solution (delete a file by mistake on your local replica -> the deletion gets replicated to the server -> you lose both copies).

You can make a JBOD array out of that using LVM (add all disks as PVs, create a single VG on top of that, create a single LV on top of that LV). But if the disks are old, I wouldn’t trust them as reliable backup storage.
My advice is get a large disk for this PC, store backups on that. You don’t necessarily need RAID (RAID is a high availability mechanism, not a backup). Setup backup software on this old PC to pull automatic daily backups from your server (and possibly other devices/desktops… personally I don’t bother with that. Anything that is not on the server is expendable). I use rnapshot for that, simple config file, basic deduplication, simple filesystem-backed backups so I can access the files without any special software, gets the job done. There are a few threads here about backup software recommendations:

Thank you for your detailed response! I will checkout JBOD arrays, if that wont work I will probably buy newer larger disks.

btrfs has this built in with additional redundancy, so that is by far the better option to combine multiple drives into one large pool.

JBOD here just means “show me this bunch of old drives as a single drive/partition”. It’s just a recommendation to at least get something out of these drives - but don’t use this as backup storage , these drives are old and if a single one fails, you lose access to the whole array.
If you’re not sure what to do with them, juste get an USB dock or USB/SATA adapter and treat them as old books, copy not-so-valuable stuff on them, and store them in a bookshelf with labels such as
