Possible Bug with SME 5.0 Frequent Recovery Point Backup


I'm trying to understand why Frequent Recovery Point backups (in SnapManager 5.0 for Exchange) throw a .NET exception. I can consistently reproduce this error. Everything else works great !!

First, here's a high-level overview of my environment:

- Windows Server 2003 SP2 w/ all current hotfixes

- Exchange Server 2007 SP1 w/ all current rollups

- Microsoft .NET Framework 3.5

- NetApp SnapDrive 6.0

- NetApp SnapManager 5.0 for Microsoft Exchange

Now, here's that .NET exception (after right-clicking on the Exchange host within SME and selecting "Frequent Recovery Point Backup") :


Unhandled Exception in Managed Code Snap-in

Any thoughts?

Hello Brian,

I have a lab which identically matches that configuration and was able to replicate the problem.

That said, I've filed a BURT regarding this issue, and I will be personally following this to see what it takes to get it resolved (be it setting or bug fix)

Thank you for your attention to the matter and verbose environmental details in order to replicate it.

Stupid question here:

did it work before?

I may have had a similar issue. I think I re-installed powershell, and whala, it started working.
