About snapshot backup methods using multiple streams

If you specified multiple stripes for any Snapshot Client backup, which streams the frozen image to tape, then NetBackup divides the number of component files equally among the number of stripes. If the number of files is less than the specified number of stripes, then the agent performs the backup using only as many stripes as there are files.

With SQL Server backups performed with Snapshot Client, NetBackup identifies all of the backup streams by the same name, such as:

juneberry.MSSQL7.COLE.db.Northwind.~.7.001of003.20141012131132..C

and are differentiated by NetBackup by their backup IDs.
