If you use Vault in an environment in which backups can occur 24 hours a day, seven days a week, a profile may try to eject media to which backups are written. Because Vault cannot suspend media on which backups are currently written, an error occurs and partial images may be vaulted. The rest of the image is vaulted the next time the profile runs if that tape is not busy and the choose backups time window is large enough to select the image again.

To avoid such problems when vaulting originals, choose backups that were created a day or more ago and suspend the media to prevent writing to the media. (This assumes that your backups are complete by the time the Vault session runs.)
