One thing rsnapshot does reasonably well is faking multiple tape rotations within the snapshot set. e.g. you say "1 yearly, 2 monthlies, and 7 dailies", and it works out which snapshots to expire. I don't know how to do that in btrfs/zfs land.
Just write a shell script to delete the ones you don't want. I have written scripts for ZFS and BTRFS to have a specified number of snapshots stored on a less than daily basis (hourly or every 15 minutes) and a specified number of daily snapshots. You could write scripts to have yearly, monthly, etc. It's just a bit of extra shell scripting. However the benefits are less (in most cases the vast majority of data that's been around for a couple of months will be around for several years). Disk space is all that limits you. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
