I dabble in the ARRs, plex, jellyfin, emby nextcloud.
I have an old supermicro server 2014 I got on eBay with dual e5 2620, 64gb RAM, and 12 hdds of various types adding to 100tb all on LVM in ubuntu. I'm planning on transitioning to UnRAID once I get the motivation because my storage hygiene is bad. I've broken LVM too often with misplaced commands.
I'm looking at making an offsite backup shortly mostly for nextcloud at a coworkers home. I am trying to get rid of my reliance on Google for backup.
My next rig I make is going to have UnRAID. I wanted to practice Lvm creation so I went with just an ubuntu setup. I've broken LVM more times than I'd prefer to admit
