Multistream backup running as single stream even when multistreaming option is selected while backing up multiple mount points -
Description
Multistream backup running as single stream even when multistreaming option is selected while backing up multiple mount points -
Cause
Multistreaming helps to Multistreaming sends data from a single client to multiple tape drives at the same time. It is advantegeous wherein the client the client is a high end client (throughput higher that the tape drives can handle). Multistreaming allows multiple backups (streams) of a single client to occur simultaneously to multiple tape drives.During multistream backups, the plug-in splits the Backup Selection Set is into smaller selection groups and uses separate child processes to perform parallel backups of these selection groups.You can use the multistream options to do the following:•Back up multiple volumes, network shares, and mount points simultaneously•Back up a single volume using multiple parallel streamsWhile configuring the multistreaming option for backing up multiple mount points if you don't select the option :Always use a new stream when crossing a mount point backup will run a single stream only -
Resolution
Always use a new stream when crossing a mount point: When you select this check box, the plug-in uses separate streams to back up the mount points that exist on the volumes. You can use this option with the Use Heuristics for large Single Volume backups option.So if you are backing up multiple mount points you should also select this option
