Exploring btrfs for backups Part 6: Backup Drives and changing RAID levels VM
Hard drives are relatively cheap, especially nowadays. But I still want to stay within my budget as I setup my backups and system redundancies.

Exploring btrfs for backups Part 5: RAID1 on the Main Disks in the VM
So, back when I started this project, I laid out that one of the reasons I wanted to use btrfs on my home directory (don’t think it’s ready for / just yet) is that with RAID1, btrfs is self-healing. Obviously, magic can’t be done, but a checksum is stored as part of the data’s metadata…
