About the list of images to be vaulted

During a Vault session, Vault builds a list of images that are candidates for duplication or ejection.

The preview.list file, which resides in the session directory for the current Vault session, includes all images that match the criteria specified on the profile Choose Backups tab except for the following:

After the preview.list file is generated, Vault evaluates the images in it to determine if they should be duplicated or ejected. Because several filters (that is, other profile configuration options) can exclude an image from duplication and ejection, the preview.list file can be a superset of the images that eventually is duplicated by the session.
