Maximum concurrent write drives storage unit setting
The Maximum concurrent write drives storage unit setting specifies the number of tape drives that NetBackup can use at one time for jobs to this storage unit. The number of tape drives available is limited to the maximum number of tape drives in the storage device. If a job contains multiple copies, each copy applies toward the Maximum concurrent write drives count.
When selecting the value for Maximum concurrent write drives, use the following guidelines:
Storage unit that contains only standalone tape drives
Specify a number that is less than or equal to the number of tape drives that are in the storage unit.
Robot
Specify a number that is less than or equal to the number of tape drives that attach to the NetBackup media server for the storage unit.
Assume that you have two standalone drives of the same density and specify 1. Both tape drives are available to NetBackup but only one drive can be used for backups. The other tape drive is available for restores and other non-backup operations. (For example, to import, to verify, and to duplicate backups as source.)
Note:
To specify a Maximum concurrent write drives setting of 0 disables the storage unit.
