Issue



 When backing up a Virtual Machine that has Microsoft SQL Server, Exchange Server or Active Directory installed on it and Application GRT is enabled, if the data for these applications is stored on an iSCSI or SAN drive the backup will fail with one of the following messages.


Error



Error 1:
Final error: 0x3 - The system cannot find the path specified.
Final error category: Other Errors

Error 2:
Final error: 0xe000fedf - A failure occurred reading an object.
Final error category: Resource Errors

Error 3:
V-79-57344-65247 - Error. Cannot backup directory \zzzVirtApp000zzz and its subdirectories.
The debug log (BEREMOTE) on the media server will show one of the following errors:

Cause



This error occurs when the application data (databases) are stored on a drive that is not part of the virtual machine configuration. 

Example Virtual Machine:
C drive is located on drive1.vmdk
D drive is located on drive2.vmdk
E drive is located on a NAS device connected to the virtual machine via iSCSI or SAN

In this configuration Microsoft SQL 2008 is installed on the virtual machine with the default data path for the databases is pointed to a directory on the E drive.

When a backup of this virtual machine is performed only the C and D drives are backed up, the E drive is skipped. The GRT process of the backup starts during the job it is unable to mount the E drive to build the restore selections for the E drive, which causes the job to fail with one of the above error messages.

Note: This issue can also occur if the data files for the application are stored on an RDM drive.


Solution



Application GRT is not supported in this configuration since all of the drives are not backed up by AVVI. 

To allow for individual item restore from the SQL, Exchange and Active Directory agents a remote agent backup will have to be performed for that application.
