So, is anyone doing automated snapshots? Care to share your technique or wizardry? Allan Jude's ZFS book mentions a FreeBSD package called "zfstools," which is apparently a collection of cron-based scripts in Ruby (https://github.com/bdrewery/zfstools). I haven't used Ruby before, and the scripts would probably need to be modified to work with launchd instead of cron. Has anyone done this? The scripts are quite elegant, and make use of ZFS properties to control how they work.
I also came across some scripts written in Bash shell: https://bitbucket.org/mmichele/zfssnap . These look a little more universal, a little more primitive, but definitely portable to OS X. Has anyone worked with this one, either?
If no one has done it, I'll probably work with the Bash scripts to implement something eventually.
Thanks,
Kurt
