Is the concept of "refreshing" volume groups possible on an existing copy of a volume group? Let me rephrase. Say I setup a volume group (VG) of 24 volumes (PRD01) that are for a production database. I want to snapshot that group of 24 volumes and create a copy of it to repurpose as a prod support DB copy (COPY01) and another copy to mount on another server to get backed up (COPY02). When its time to backup the server again can I refresh the data of PRD01 group to COPY02?

yeah vgroups are more of a reporting/grouping function today, not so much for features. The only storage feature available really on them is QoS. So you would want to put them in a pgroup with a local snapshot policy enabled or no policy at all and take pgroup snapshots as needed

this will create write-consistent snaps across all volumes in the group

you would probably use protection groups for this

Ok i'll read about those more.. from first glance it seems those were for sending copies remotely

And maybe its just the v6.1.19 that we currently have, but is there a shortcut for creating snapshots for an entire "volume group"? Or will that be what a protection group is for also?
