Deleting Snapshots older than 2 weeks across multiple pools

[GJSchaller]

My NAS is currently set up to take daily snapshots of my main pool ("data"), and set to keep them for 2 weeks. I also have a daily replication task to back up the data, using that snapshot, to an external drive (which is its own pool).

This morning, I looked at my snapshots in the UI, and saw many old snapshots, across multiple pools - the main pool, the external drive, and some others as well.

Is there a way to delete all backups older than X time (such as 2 weeks) across all pools?

I did search and find some older threads on this, but nothing that will do it across multiple pools.

I also found https://github.com/bahamas10/zfs-prune-snapshots but I am not sure how to implement this on TrueNAS. Is this something that would be used under TrueNAS?

Thank you!

working for me... example (from System Settings -> Shell):

wget https://raw.githubusercontent.com/bahamas10/zfs-prune-snapshots/master/zfs-prune-snapshots chmod ug+x zfs-prune-snapshots ./zfs-prune-snapshots -vn 1M
