    At the end of this week I'll be doing a DR test with CommVault v11.  I've done 5 previous tests but this is my first with v11 and I still have some residual concerns over the v2 indexing.

    My DR contract is for a cold site.  We have no access to it except during an actual disaster and during the annual test, so I can't replicate anything to it--everything must be carried in with backup tapes and USB drives, etc.

    Nearly everything in my environment is backed up as a VM in using the virtual agent, but I do have some database servers where I back up to disk and then back those backup files up using a windows file system agent.  What do I need to do to prepare for that? 

    Will the Aux Copies of my backup jobs be enough or will I need some collection of the Index Backups as well?

    HI Boberic,

    right now the best way to deal with this is to ensure you keep 30+ days worth of indexbackups AUX copied to your DR site.

    Just to clarify, the index restores prior to browsing the tape copy of each job happened pretty much the same as previous versions.  

    I did not need to do anything special with restoring the Index cache backup.  I'm not sure if that was because pretty much all my restores were from virtual agent based (i.e. I use VMware VMs rather than physical servers for everything) but at least things didn't get any harder than on V10. 

    Additionally, the DR restore process for the CommCell is indeed easier on version 11 than on version 10.
