CatDV Desktop Archiving Option Unlimited CAUL with modern tapeless workflows it is important to be able to archive and back up your media files. The CatDV Archiving Option provides integrated support making it easy to archive files to a Cache-A LTO archive appliance by copying files to the Cache-A vtape folder and keeping track of which tape they have been archived to.  Once files have safely been archived, CatDV provides the option to purge those files from local storage, but low-res proxies and a searchable database of all your log notes and other metadata make it easy to find those files again, and request that they be retrieved using the Cache-A interface if they are currently offline.
