I’m running my media server with a 36tb raid5 array with 3 disks, so I do have some resilience to drives failing. But currently can only afford to loose a single drive at a time, which got me thinking about backups. Normally I’d just do a backup to my NAS, but that quickly gets ridiculous for me with the size of my library, which is significantly larger than my NAS storage of only a few tb. And buying cloud storage is much too expensive for my liking with these amounts of storage.

Do you backup only the most valuable parts of your library?

    4 bay nas 22tb drives = 88tb as a single volume. Backed up to offline single storage drives that are timestamped. Anything newer than that timestamp gets rsynced/robocopied to a new drive until it’s full., update timestamp, swap drive and rinse repeat. If a drive fails, just replace it and copy the contents of the backup drives to master and restored. Alternatively you can set a single disk tolerance raid.

    @anzo

    an unholy ensemble of 4 external drives and 2 cloud storage providers managed with git annex
    capacity: 3 TB + “pay as you go”
    available: 1TB
    used: 1.01TB
    the drives were originally 5, then 1 failed and added the “pay as you go” s3 provider to pick up the slack
    git annex handles redundancy and versioning, i configured it to keep 2 copies of every file across the 4 drives and the s3 provider, then i got 1tb of free onedrive space from my university and i’m in the process of making a full backup of everything in there
    not really backup as much as redundant storage, but i think it’s close enough

    if anyone wants to roast my setup please do

    Used to use rclone encrypted to gsuite, until that gravy train ran out lol.

    Now I’ve got 3 Unraid boxes (2 on site, 3rd off) and a metric shitton of drives I’ve accumulated over the years.

    Unraid checking in. 150TB ish. Dual parity for media files on XFS drives. Can lose 2 drives before array data is at risk, and even then if a drive fails, I’d only lose the data on that drive not the entire array.

    Important data is on ab encrypted ZFS array which is snapshotted and replicated hourly to a separate backup server and replicated one more time weekly to 3.5” archive drives which are swapped out to a safe deposit box every few months.

    I used to use rsync to do it but snapshot replication with sanoid/syncoid does the same thing in a tiny fraction of the time by just sending snapshot deltas rather than having to compare each file.
