Use this dialog box to enable or disable multiplexing, and to enable or disable the Erase Media on Prune feature.
Optimize Media Usage
Allows you to specify the number of streams that an auxiliary copy operation can be combined to. If one stream is selected, then the auxiliary copy operation will copy the data from all streams to one data stream. If cleared, the auxiliary copy operation will copy the data using multiple data streams.
Note that multi-stream backups of the DB2, Microsoft SQL Server, and Sybase agents will not be copied to a copy that combines streams.
If selected, data protection operations of multiple data streams can be run concurrently to the same media. If disabled, data protection operations to the same media must be run individually. An Auxiliary Copy can be configured with Data Multiplexing when the source copy is enabled for Deduplication.
Select how many data streams from this storage policy are to be backed up concurrently to the same media.
If selected, the data streams are copied to each available drives first and then fills up the used up drives (spill and fill). If disabled, all the data streams are copied to one drive and once it is filled up, moves to the next drive (fill and spill). However, in case of Oracle jobs, if the Enable Multiplexing for Oracle option is not selected from the Job Management (General) dialog in the Control Panel window, then enabling/disabling this option will only allow the data streams to be copied to each available drives first and then fills up the used drives (spill and fill).
Write to a Different Library Compared to Source Copy
Click to prevent a job from being copied to the same library during auxiliary copy operations.
If selected, for the storage policy copy using removable media (tape or optical media), the media will be marked for erase, when the media is recycled.
Note that the Erase Spare Media operation must be initiated to actually erase the contents of these media.
This option is not applicable for storage policy copies with destinations pointing to disk or stand-alone libraries.
Enable Media Refresh
Select the option to enable media refresh for the copy. Use the following options to specify the criteria.
Select the number of months. Media that were not written to in the specified number of months will be picked up for refresh.
Specify the number of months. Media with specified number of months or more before aging will be picked up for refresh.
Select the option and specify the media capacity in percentage. Media with data less than or equal to this capacity will be picked up for refresh.
Select this option if you wish to refresh media that exceeded the retirement threshold.
