You use the Policies resource to create a life cycle to use for both the Failed Cross Reference Format and Failed Cross Reference Format for your backed-up data. The client resource already has a default browse policy of Month and a default retention policy of Year assigned.
The browse policy determines how long the client file index maintains a browsable entry. If the browse policy has not expired, you can view the data in a graphical representation of the filesystem backed up, using the nwrecover program. After the browse policy expires, you can still use save set recover or the scanner program to recover the data, because save set information is still stored in the media database.
The retention policy determines how long the save set information is stored in the media database and how long the file remains retrievable from the backup volume. After all the retention policies for the save sets on a volume and other dependent save sets stored on other volumes expire, the volume is given a recyclable status and is available for reuse by Backup. Until the volume is relabeled, you can still use the scanner command to recover the expired save sets.
