Here it is on the company website: http://www.brockmann-consult.de/peter2/zfs.tgz Disclaimer/notes: -provided as is... might destroy your system, furthermore, I am not responsible for bodily injury nor nuclear war that may result from misuse -there are no unit tests, and no documentation other than a few comments that are possibly only coherent when I read them. For example, it says that it does it recursively and rolls back the destination dataset, but there are a few undocumented cases I can't remember when I needed to do something manual like delete a snapshot, or destroy a dataset. Maybe that is all in the past. I don't know. -the zfs_repl2.bash is the one that makes snapshots and replicates which I wrote myself. The other ksh one is the Oracle one I linked above, and the .sh version of it was just what I was working on to try to make it work reliably, before redoing it all myself (reinventing the wheel is indeed fun). -especially beware of the deleteOldSnapshots.bash which is not well tested and not used yet (and deleteEmptySnapshots.bash which does not work and I believe cannot work). -granted transferable your choice of any present or future version of the BSD or GPL license and another note, I meant to study these which might be better versions of the same thing, or something different, but never got around to it: /usr/ports/sysutils/zfs-replicate/ /usr/ports/sysutils/zfsnap/ /usr/ports/sysutils/zfs-periodic
