Discussion: how are you protecting your data?

[marktheblue45]

I thought so. Weird thing with the exchange mail stores and logs. Snapshot produces 5 snaps not one per volume. SQL DB and logs behave as I'd expect. One snap operation per volume = 0ne snap on Nimble.  

Not quite there yet..

I have discovered the following:-

Vol collection contains 6 DB and 6 log volumes and the collection show 6 snapshots corresponding the the Commvault Job ID. Unfortunately the individual volumes show 6 snaps each. Therefore 12 volumes with 6 snapshots = 72 snaps. I'm missing something or else there's a bug/limitation here?

Mark,

In the lab I configured two Exchange 2010 databases to be protected with a single Simpana subclient:

- 2 Exchange database volumes

- 2 Exchange log volumes

- All volumes (4) in the same volume collection

- 1 Simpana subclient (Exchange Database) with the contents of both databases (Microsoft Information Store\DB1 & Microsoft Information Store\DB2) included

I see one volume collection snapshot corresponding to the single Simpana job ID, as well as a single snapshot for each volume in the collection with the same Simpana job ID.

In your use case are you protecting all 6 Exchange databases with a single subclient or multiple subclients?

Thanks, Bill

Alas multiple so I've created 6 vol collections. Each collection contains DB and corresponding log volume inline with the subclient.

We did multiple subclients to have multiple streams on the go and it's not such a chore because exchange is the only DB snap/backup configured in this way. SQL is generally straightforward i.e. A User Database and corresponding log volume pair.

Delighted so far just a shame that one can't purge out the 3 hourly (snap every 3 hours from 09:00 until 18:00) every 4 snaps like you can with Nimblestorage own snaps.

I'm sure this might become an option in the longer term because our 2 exchange server total 11 DB and log volume pairs. Commvault keeps snaps for 7 days so that's 4 * 7=28 for the 3 hourly multiplied by 22. 616 snaps plus 7 daily multiplied by 22.  154 snaps. Total snaps 770!

Good Fun,

                 Mark.

We have 2 exchange servers one with six mail stores and the othe with 5. Could consolidate into 2 subclients but not an issue now I've done the new volume collections

Thanks to everyone for their tips and suggestions. Collectively we got there in the end.

Fabulous forum
