PowerCLI: Remove Largest Snapshots First

June 9, 2014 / Nicholas Zeigler / 0 Comments

Here is a nice PowerShell one-liner to remove the largest snapshots first. This removes one snapshot at a time.

get-vm | get-snapshot | sort-object sizemb -descending | Remove-Snapshot -confirm:$false

1	get-vm \| get-snapshot \| sort-object sizemb -descending \| Remove-Snapshot -confirm:$false

If you want to do it for VMs of only a certain size, where snaps are larger than 1GB:

get-vm | get-snapshot | where {$_.SizeMB -gt 1024} | sort-object sizemb -descending | Remove-Snapshot -confirm:$false

1	get-vm \| get-snapshot \| where {$_.SizeMB -gt 1024} \| sort-object sizemb -descending \| Remove-Snapshot -confirm:$false
