snaprotate

[Ulli Horlacher <framstag@rus.uni-stuttgart.de>]

Being a Netapp user for a long time, I have always missed btrfs snapshots
the way Netapp creates them.

I have now written snaprotate:

http://fex.belwue.de/snaprotate.html

snaprotate creates and manages btrfs readonly snapshots similar to Netapp.
Snapshots have names like hourly, daily, weekly, single and a date_time
prefix.

Snapshots are stored in a .snapshot/ directory in the subvolume root. 
Example: /local/home/.snapshot/2017-09-09_1200.hourly

You create a snapshot with:

snaprotate <class> <count> <subvol>

<class> is your snapshot name
<count> is the maximum number of snapshots for this class
<subvol> is the btrfs subvolume directory you want to snapshoot

If count is exceeded then the oldest snapshot will be deleted.

You can use snaprotate either as root or as normal user (for your own
subvolumes).

Example usages:

snaprotate single 3 /data             # create and rotate "single" snapshot
snaprotate test 0 /tmp                # delete all "test" snapshots
snaprotate daily 7 /home /local/share # create and rotate "daily" snapshot
snaprotate -l /home                   # list snapshots
