# btrfs-ship
Extremely simple bash scripts to create daily incremental snapshots of btrfs subvolumes on one server and pull them incrementally from another server.
Incrementals are rotated for one week, e.g. `@subvol-mon`, `@subvol-tue`, ... `@subvol-sun`.
TODO:
- script to start / repair incremental set-up
Expected set-up:
- btrfs subvolume at `/some/path/@subvol` on source server
- `btrfs-snap.sh /some/path/@subvol` run daily on source server
- ability of the destination server to ssh to source server
- `btrfs-pull.sh -r /dest/path -s @,@subvol -h srcserver:/some/path` run daily on dest server
Typical crontab entries:
``` cron
# btrfs snapshots just before midnight
55 23 * * * root /home/src/btrfs-ship/btrfs-snap.sh /mnt/ssd/@ /mnt/ssd/@home >>/var/log/btrfs-snap 2>&1
```
``` cron
# Mirror btrfs snapshots from srcserver
7 0 * * * root /home/btrfs-ship/btrfs-pull.sh -h srcserver:/mnt/ssd -s @ @home -r /mirror/srcserver >>/var/log/btrfs-pull 2>&1
```
Initialize:
- run `btrfs-snap.sh` on source server
- rename `@-xxx` to the previous day `@-yyy`
- copy snaps using `ssh srcserver btrfs send /mnt/ssd/@-yyy | btrfs rec /mirror/srcserver`
