I’m using BTRFS on my home server. One of subvolumes is called media and is used to store curated collection of personal
and professional photos, movies, books, etc. for whole family. In this post, I will share my experience with backing
the whole media NAS share (currently 116 GiB).
Backup procedure
Consistency - preparing backup source
First snapshot
btrfs subvolume snapshot -r /mnt/t20raid/svols/media /mnt/t20raid/snaps/media/2022-05-31
Create a readonly snapshot of '/mnt/t20raid/svols/media' in '/mnt/t20raid/snaps/media/2022-05-31'
restic backup to Storj via S3 gateway
Retrieve everything from Storj….
