Restoring a multiplexed SQL Server backup
In most cases, Veritas does not recommend multiplexing multiple SQL Server streams from the same backup to a single tape. However, you may want to do this if you vault or export backup images. During the restore of this type of multiplexed backup, NetBackup may time out while trying to synchronize access to data blocks from the backup tape. To prevent this time out, change the stripes parameter in the recovery batch file from STRIPES N to STRIPES 1.
When you change this value it causes the restore to be performed in a single-stream. NetBackup presents the N backup images to SQL Server one at a time. The tape is rewound between the restore of each image.
