, ease of deployment, and an architecture that enables core backup data to remain on disk and online longer can help organizations reduce the complexity associated with backup. In most cases, a Dell DR4X00 solution replaces a tape drive or library as the primary storage target because the DR4X00 - Dell PowerVault Storage Area Network | Best Practices for Setting up NetVault Ba - Page 5
(nVTL) DR4X00 replication support is achievable using this method. See Figure 1 below which illustrates the DR4X00-NetVault nVTL baseline Scenario.

the customer has to backup and the required retention periods for each set of data so as to not exceed either one of these two guidelines when creating the virtual media for the virtual tape library 7 Setting up NetVault Backup Native Virtual Tape Library on the Dell™ DR4X00 Disk Backup Appliance - Dell PowerVault Storage Area Network | Best Practices for Setting up NetVault Ba - Page 8
. It is important to also never exceed the number of streams supported by the appliance vendor's operating environment when creating VTLs and virtual drives. Media size is the final consideration when creating a VTL. Unlike physical media, virtual media can be created to any size within the allowed - Dell PowerVault Storage Area Network | Best Practices for Setting up NetVault Ba - Page 9
would not be reclaimable by the DR4x00 clean cycle. Keeping spare media that is not grouped blank will keep the usage of the DR4x00 unit as low as possible. Because the Automatically Label Blank Media option is disabled, the backup may run out of media before it completes, especially if the data - Dell PowerVault Storage Area Network | Best Practices for Setting up NetVault Ba - Page 10
a media utilization report (job ID 13) to be sent to the sysop on a reoccurring basis to track the media usage. This will allow the sys-op to pre-add media to help prevent the above scenario. 10 Setting up NetVault Backup Native Virtual Tape Library on the Dell™ DR4X00 Disk Backup Appliance - Dell PowerVault Storage Area Network | Best Practices for Setting up NetVault Ba - Page 11
