I’ve used OpenMediaVault for years and liked it, but I’m just exploring some other options. I’ve got a new system with a Ryzen 370 and 890m iGPU, which Debian is fighting me on getting working. Meanwhile it looks like AMD is treating Ubuntu as a first class citizen for support. Just considering options, maybe Ubuntu plus Cockpit to abstract all the admin stuff?
Depends what protocols you need?
If you use SMB install the Samba server package. If you use WebDAV install a WebDAV server like SFTPGo, etc…
If you want a google drive like replacement there’s Nextcloud, Owncloud, Seafile, and others.
For the drives themselves you can have traditional RAID with MD, or ZFS for more reliability and neat features, or go with MergerFS + SnapRAID, or just directly mount the disks and store files on some and backup to the others with Restic or something.
Lots of options!
