We have an outside tool that creates snapshots, however it won't clean them up. Does NetApp have a native way to clean them up after they reach a certain age? Maybe a tool?

if they're taken manually, i don't think that applies.

Script could be straight-forward with queries.

snapshot delete {* -create-time <1d}

Is a script secure? Don't want to give a backdoor to an attacker

snapshot autodelete can delete all snapshots, manually or automatically-created, but it waits till the volume (or snap reserve) is full, and not until a certain time has passed. that's why it can be abused

#

and a script needs credentials of course, which must be stored somewhere on the server where the script is. But if an attacker is already that far inside your system, it's too late anyway 😂

yea, with a script you can also encrypt the password/etc
