BE 2012 ADBO + DFS replication - options?
We have BE 2012 with ADBO on a Win2008R2 server, backing a Win2008R2 file server with 600GB data stored on a SAN volume. The SAN is a Dell MD3200i, with hardware snapshots enabled. Approximately half the data is held in DFS replicated folders.
When I run a backup, using Shadow Copy Components for the DFS folders, the job fails with an error:
" - Snapshot Technology: Initialization failure on: "\\YHRHPAFIL001.xxxxxxxx.xxx\Shadow?Copy?Components". Snapshot technology used: Microsoft Volume Shadow Copy Service (VSS).
Snapshot technology error (0x800423F8): 0x800423f8 (2147755000)
Check the Windows Event Viewer for details."
When I run an offhost backup, the data in the DFS replicated folders does not backup. The job fails with an error:
"V-79-57344-65033 - Directory not found. Cannot backup directory #User?Data#Distributed File System Replication#DfsrReplicatedFolders#Accounts#Region#Accounts and its subdirectories."
It seems then that I cannot backup DFS replicated folders when using the off host backup option because they need the volume shadow copy provider, but I cannot back them up using shadow copy comonents either, as snapshots on that volume are now provided by the SAN hardware!
Can anyone suggest any options, short of separating DFS replicated folders and non-DFS replicated folders onto different volumes and running separate backups for each? This would render the off host backup option a bit pointless!
