DP 6.0 and Exchange 2003 Info Store

[N__K]

Hi,

I am using DP6 to Backup MS Exchange 2003 Info Store.

We faced a space issue so I delete most of logs.

Now, I am getting this alert in the Backup Status.

From: OB2BAR_First Storage Group@oppcluster1.omanpp.com "Microsoft Exchange Server (Microsoft Information Store)" Time: 1/11/2009 1:09:01 AM
ESE subsystem or operating system reported error for First Storage Group:
0xc7ff1004: Error returned from an ESE function call (%d).


Is it compromise Restoration?
It is risky?

Please advice,

Best Regards,
