I use a python script via cron job, it checks how many snapshots exist and removes those that 
exceed a configurable limit, then creates a new one. 
Deployed via puppet it's much less hassle than click around in a GUI/

> Snapshots can also be created from the Scale GUI. The GUI also provides its own
> automation for the creation, retention, and deletion of snapshots.

> My question is: do most customers use the former or the latter for automation?

> exactly the same as what the GUI does it terms of creating automated snapshots.
> It is a relic of V7000 Unified but still works fine in Spectrum Scale
> How many customers also use the commands found in /usr/lpp/mmfs/gui/cli / ? )
