VSS backup issue
Hi all,
I am just wondering if any of you have seen this issue before. I have 4 node Microsoft clusters(window 2008 ent). I use Flashbackup-windows policy type to backup file resources on this cluster that have LUN presentations on HP EVA using off-host backup. As such HPVSS component was installed on all the nodes to make this off-host backup work.
The snapshot backup is working fine for this policy type. However there are other resources on this cluster that uses MS-windows-NT (network) policy type to backup their own resources. I suppose by default the open file backup for those reaource should use microsoft VSS and not creating snapshot on the EVA. But i found out that even the MS-windows-NT policy is creating snapshot on the EVA for LUN presented to those resources that are being backed up by MS-windows-NT policy.
Does this mean that because HPVSS is installed on those nodes, it has over taken or wrapped up the microsoft VSS and It is choosen as the default VSS provider for all policies . and where the drives being backed up reside on array, a snapshot of that volume is created on the array? The backup of the nodes( local drives C and shadow copy component) them self seem to use microsoft VSS provider as the backup selection includes no LUNs that resides on EVA.- right?
Any idea? Please.
Thanks.
