I've got something of an interesting situation that I'd appreciate some feedback on.
We've got a client who has snapvault. For regulatory reasons they want to keep 7 years worth of monthly snapvaults = 84 snapshots - so far not an issue.
They also want to move to snaplock compliance - also not an issue.
What is an issue is that snapvault is in place now and has several end of month backups but the area is running out of disk space, space will be added but looking at the long time requirements this snapvault could very easily outgrow the OnTap 8.1 max volume size requirements plus there may be a need to move some data round to fit slightly different retention schedules.
So, the main question is really - how do I move, say HALF the snapvault destintations to another volume/filer AND if I do the move what happens to the snapshots?
Let me give an example - lets say that I've got an Exchange server and a SQL server snapvaulting to the same volume,
If that SQL server snapvault grows to 16TB (which is possible) then how do I move it to another volume and what happens to the snapshots? What I'm trying to avoid is having 'ExchangeA' sitting in different volume to its legacy snapshots so it's it possible to move those snapshots as well? are we talking a snapmirror then delete what I don't need? Won't those volume snapshots have data thats no longer of use?
As you can see, I'm a but confused as to how best to move the snapvaults around but also maintain a coherent snapshot policy for the regulatory compliance. I really don't want to have legacy snapshots on one volume and the data on another and I don't want to drag around unnecessary data.
