Dell DR4300e NetVault Backup - Best Practices for Setting up VTL Containers an - Page 37

Space reclamation from the virtual media of a NetVault Backup VTL hosted on the DR Series appliance has some specific requirements. Even though NetVault Backup can locate and blank media that is marked for reuse, the DR Series appliance will not know that NetVault Backup has marked the media for reuse and will not reclaim the space on the next clean cycle. This is because the NetVault Backup only updates its database information on the media and does not scrub through and remove the old data. To ensure that the clean cycle on the DR Series appliance can reclaim space, the markedfor-reuse media must be identified, blanked using the nvmakemedia utility, removed, and then added again as a new file. Because the new file no longer has any content, the clean cycle can reclaim the space. A script can be run to build a list of the media, blank it, and use the nvmakemedia utility to re-create the files. For a sample script that can be modified for either type of installation, see Error! Reference source not found..
