Issue/Introduction

It  is possible to restore only one file when the disk volume has been backed up by VBACKUP utility ?

 

Environment

Release : 12.5

Component : CA Disk Backup and Restore

Resolution

The only type of restore is either by volume or specific tracks.

During the VBACKUP the RPT=MAP can be set.

RPT= Specify this parameter with a value of MAP to produce a report for each DASD volume processed. This report will include information such as data set names and extents,which permits to recover the file indicating the CYL0TRK0.

The CYL0TRK0= parameter controls the recovery of the data records, if present, on cylinder 0, track 0. This track is a reserved track on each volume containing a pointer to the VTOC, the volume serial, and other optional data. It often includes IPL text.


When a volume-level recovery is performed, the pointer to the VTOC is always updated to reflect its location on the recovered volume. The default value of YES for this parameter causes all data records on this track to be recovered from the backups. If you specify a value of NO, only the VTOC pointer is updated (and the volume serial, if it is being renamed).

This parameter applies only to a full volume-level recovery; that is, it is mutually exclusive with the ABSTRKS= parameter described in the following section.
