zero length snapshots

[Hr46ph]

Did a search but couldn't find this being asked previously.

Some of my datasets change very little and making regular snapshots result in multiple zero byte snapshots.

Is there a way, or would you consider this a feature request, to have zfs-snap-manager not make a new snapshot if the previous one is zero bytes? Other options would be to change its name to the current date, or remove it and make a new one.

Either way, I am now creating scripts to perform maintenance for something that I believe would be better suited by zfs-snap-manager.

Thanks!

@Hr46ph did you make any progress in your own maintenance scripts? First idea is to use the postexec section or extend the existing Clean.py. I also have some datasets fitting into your issue description.

No, but I have since moved to Sanoid, more features and more actively developed. I've submitted the same request there and for now I either remove them manually or ignore them.

Its not an issue per se, zfs doesn't care. So its purely cosmetic and for usability (cleaner list).

I'm closing this issue as I unfortunately don't have the time anymore to maintain ZFS Snapshot Manager. I would like to point you towards the awesome tool zrepl which has nearly all of ZFS Snapshot Manager's features and much more.

In any case, thanks for being a part of this community.
