z3 VS zfs-to-aws

Z3 doesn't seem to be maintained. This script seems to be a oneoff. ZFSBackup Go seems more full featured but also unmaintained and out of date as well.

To add, i'm not so confident in future usability given it's python 2[0].

I've created similar functionality just using bash that will send the lates version of ZFS datasets to S3/Glacier, including dealing with incremental changes. I have mentioned this previously on HN and got a few useful changes submitted for it, especially making it more platform agnostic.

I have some open tickets asking about restoring. I haven't tried this yet as this has been a backup of last resort for me, but hopefully posting this again will nudge me into looking at that.

For anyone who might be interested in doing this with fewer dependencies/tooling I have written a bash script that pushes ZFS snapshots to S3:

I have it running in a cronjob on my NAS nightly, and a retention policy on aws to push it straight into glacier.

There's no restore script as this is my last line of backups, so I thought if I was restoring from here I'd want to do it manually. I might get around to writing one now however.
