Hi,
We had a Windows 2003 server with SQL Server 2005 installed that was backed up using a DP 6 file system backup. The SQL Server was backed up seperately.
This server was then virtualised and the O/S was upgraded to Windows Server 2008 R2 Std.
Now, when the backup runs, in the SQL Server log there are the following messages:
I/O is frozen on database msdb. No user action is required. However if I/O is not resumed promptly, you could cancel the backup.
I/O was resumed on database msdb. No user action is required.
Database backed up: msdb ....
This is reported for all the databases.
The backup is just a filesystem backup with the SQL Server datafiles excluded, so no database backups should be performed.
I had read that these SQL error messages could be related to VSS, but "Use Shadow Copy" is not specified in the backup.
I have done two things to try to identify if it is VSS,
1. Enable "Use Shadow Copy" for the backup and save it. Checking the file for the backup I could see -vss specified. I then disabled "Use Shadow Copy" and saved it. This time checking the file for the backup I could see -no_vss specified.
The only problem with this was that when the backup ran, it didn't like the option -no_vss, even though it was put there by the application.
2. I disabled the SQL Server VSS Writer service on the server.
This time there were no I/O messages reported by SQL Server.
As far as I can see, the only thing that changed was the O/S from 2003 to 2008. I know this is an old version of DP, and am wondering if 2008 R2 was not supported.
Any ideas,
Thanks
