Keep True Image Restoration (TIR) Information

The Keep True Image Restoration (TIR) Information property specifies the number of days to keep true image restore information on disk. After the specified number of days, the images are pruned (removed). This applies to all policies for which NetBackup is collecting true image restore information. Default: 1 day.

When NetBackup performs a true image backup, it stores two images on the backup media:

• Backed up files
• True image restore information

NetBackup also stores the true image restore information on disk in the /usr/openv/netbackup/db/images directory and keeps it for the number of days specified by this Global property. Keeping the information on disk speeds up restores. If a user requests a true image restore after the information has been deleted from disk, NetBackup retrieves the required information from the media. The only noticeable difference to the user is a slight increase in total restore time. NetBackup deletes the additional information from disk again after one day.
