An Exchange Information Store (IS) backup to a Backup-to-Disk Folder fails with the error: "Backup- \\Exchange\Microsoft Information Store\First Storage Group Database was not found, or could not be accessed."

Exact Error Message
Backup- \\Exchange\Microsoft Information Store\First Storage Group
Database was not found, or could not be accessed.
Database was not found, or could not be accessed.


Details:
In some cases, when a Backup Exec for Windows Servers Exchange IS backup with GRT (Granular Restore Technology) enabled is targeted to a Backup to Disk device, the job may fail with the following error: Backup- \\Exchange\Microsoft Information Store\First Storage Group Database was not found, or could not be accessed.

This error can occur on full or incremental backup types. In addition to the failure, a debug of the local Remote Agent service will display the following error: JetExternalRestore(2) - ERROR::RC = -1022 - -1022 There is a disk IO error

Potential solutions:

1: This issue will occur if the IMG folder used to store GRT related data is being scanned by anti-virus software while the backup is running. To resolve this issue, remove the IMG folder from being scanned by the local media server's antivirus. NOTE: IMG folders are located in the root of the target Backup to Disk folder.

2: The steps described in Microsoft KB article 304101 (see acknowledgements) for Registry setting 1 will need to be applied to the Backup Exec media server.  A reboot on the media server is required after making these changes.

3. This issue can also occur if the drive which hosts the Backup to Disk folder is fragmented. A disk defrag will need to be preformed for the backup to complete successfully.

NOTE: If the -1022 error in the debug is followed by: "StopVirt FAILED!  RC = 1450 (0x5aa) - Insufficient system resources exist to complete the requested service", the following suggestions should be tried:

1. For media servers with more than 3 Gb's of RAM, the 3 GB switch can be set in the boot.ini file on the Backup Exec media server (see acknowledgements)

2. Due to how Backup Exec handles mapping the Exchange database in memory, some databases (typically large databases, or databases with a large amount of logs) require more virtual memory than a 32bit server can provide. These limitations can be avoided when using a x64 bit server, and as such may require Backup Exec to be installed onto a x64bit Windows server.
