Automatically aging snapshots

[VulcanRidr]

On my FreeBSD boxes, I use zfs-auto-snapshot from the zfstools to make the following series of snapshots:

• 4 frequent, every 15 minutes
• 24 hourly
• 7 daily
• 4 weekly
• 12 monthly

...To give me a year's worth of snapshots. Now on TrueNAS, the menus appear to give me the option of "what dataset do you want to snapshot" and "how long do you want to keep them"?

Is it feasable to either include zfstools or write that type of flexibility into the middleware layer?

Thanks,

In the same boat as you:

"Smart" periodic snapshots? Dynamic expirations and "lifespan bumps"?

You can tell I twisted my brain into several knots trying to muster a title that can describe my question... Is it possible to create a single periodic snapshot task that follows the same principles of "smart" backups? For example, from a single task... Snapshots are created daily and marked...

Just create 5 tasks with the desired frequency and retention period.

Well...5 tasks per dataset...

There's a recursion option. I organise my datasets into top level "classes" like "share", "data" (the bulk data directories mounted in jails like Nextcloud), "vm" (zvols that provide virtual disks), etc. Then apply one policy to each of those "classes".
