Finding Large Snapshots


A very useful command to search the entire cluster for snapshots older than a specified number of hours is this:

volume snapshot show -create-time <1000h -fields create-time, size

This helped hugely to track down old snaps and zap 'em. One was 3.1TB !

So taking this theme and developing it I now want to find any snapshot accross the cluster bigger than a specified size. However the same type of command doesn't work:

volume snapshot show -size <100GB -fields size

What am I doing wrong ?? Or does anyone know of a command which will displat snapshots for all volumes over a certain size ??


Many thanks !

Thanks - works a treat. Easy to find anything which is a concern.

Re: Finding Large Snapshots


I run these commands...


When to check after forgotten snapshots, a specific year and exclude of a specific vserver:

::> snap show -create-time *2018* -vserver !*BACKUP*


When to check after snapshots bigger than a certain size:

::> snap show -size >1t
