Within the time period specified in the search range fields, CA VM:Backup restores the most recently backed up version of a source file space in the source user storage group. If this version is from an incremental backup, to restore this version, CA VM:Backup goes back to the full backup of the file space for authorizations and other object metadata.
To restore a version other than the most recent, change the To date to an earlier date. For example, if today is 1/7/15 and you want to restore a version of the file space from before 1/2/15, change the To date to 1/1/15 and the time to 23:59.
Because of the way CA VM:Backup stores file pool information in the catalogs, specify a start date when restoring a user storage group. The start date prevents CA VM:Backup from restoring more data than you intended. For example, suppose that you want to restore a user storage group from which you deleted many file spaces on 12/01/14. You do not want CA VM:Backup to restore the deleted file spaces. To make sure CA VM:Backup does not restore the deleted file spaces, specify a start date that is later than 12/01/14, but early enough to contain the data you want to restore. If you do not specify a start date, CA VM:Backup uses the default start date (01/01/1942) and continues searching for and restoring file spaces back to that date.
CA VM:Backup restores a file space only if it was backed up at least once during the date range. However, when it restores a file space from an incremental backup, CA VM:Backup goes back to the full backup for metadata even if that backup was performed before the start date.
