Use this dialog box to manage media resources.
The following properties are displayed:
| Allow media used by SILO archive job to contain data from different SIDB stores | Specifies whether a single media used by a SILO archive job can contain data from different SIDB stores. The value '1' represents Yes, and value '0' represents No. The default value is set to 0. |
| Force to use the same Media Agent for create index and backup phases during NAS backup reservation | During NAS backup, this option allows to forcefully run the backup phase on the same MediaAgent where the create Index phase was ran. The value '1' represents Yes, and value '0' represents No. The default value is set to 0. |
| Disk volume physical size high watermark in GB |
Specifies the maximum size of the disk volumes, reaching which, a new volume will be created.
The default value is set to 25 GB. You can set the value between 0 -
1,000. If the value is set to '0' the high watermark check is disabled. |
| Maximum allowed number of drive reservations per NAS Filer | Specifies the number of tape drives that can be in use on a particular NAS file server. This is useful since some file servers have a limit to the number of concurrent backup or restore jobs that can be run. The number entered will limit the number of tape drives that can be in use at a given time. For example, if five backup jobs were started for a particular NAS file server, but the number specified with this option was set to four, then the fifth job will be held in a waiting state until one of the jobs completes. |
| Interval (in minutes) to calculate valid data size for streams |
Specifies the interval at which the valid data is checked to calculate
the data size for streams. Default interval is set at 60 minutes. You
can set the value between 0 - 1440. If the value is set to '0' the data size calculation is disabled. |
| Data Threshold (in GB) to decide how to distribute data among streams for backup |
Specifies the maximum amount of data that can
be distributed among streams. While backing up to multi-stream storage policy, by default, the first few streams in the storage policy accumulates a large percentage of data which gets protected. This results in non-optimal usage of number of streams during Auxiliary copy job, where the streams with large data will keep transferring data, while other streams will not have any data to transfer. Therefore, all streams will not be used during Auxiliary copy job, even if there are resources available to use. This will reduce the overall throughput of the auxiliary copy job. With this option, the maximum amount of data can be distributed among streams. Default value is set to 500 GB. You can set the value between 0 - 5000.If the value is set to '0' the data threshold is disabled. |
