Keywords: Backups, BTRFS, Bitrot



just completed re-organizing 8TB of backups across 3 devices.... amazing how quick and how long it takes to re-organize a backup and archive strategy to free up disk space on a main file server.
 
1. main backup - rolling
2. secondary backup - rolling
3. tertiary backup - archive
4. cloud backup - includes 1, 2, 3
 
Raid 5 won't protect again bitrot, but btrfs does.
 
more to come...
