BACKUP and INSVIRMEM Insufficient Virtual Memory?

» close window

The Question is:

 
While doing an image/backup of a disk drive, I received the following error.
LIB-F-INSVIRMEM, insufficient virtual memory error.  How do i know if my image
 backup is complete to be able to restore the image?

The Answer is :

 
  The OpenVMS Wizard would not expect to see this particular error from a
  BACKUP operation, as the facility (LIB) is not what would be expected
  here.  (If there is a LIBRARIAN operation involved in the BACKUP, then
  this error might well be relevent, however.)  For information on the
  insufficient virtual memory (INSVIRMEM) error please see the OpenVMS
  Frequently Asked Questions (FAQ) discussion of this error.
 
  For information on recommended process quotas for BACKUP, please see
  the current version of the OpenVMS System Management Essentials manual.
 
  As for knowing whether or not this or any other BACKUP operation will
  be restorable, the answer is the same as any other archival operation:
  you must test the restore pass.  The BACKUP archival pass is never the
  most interesting and most important part of the entire operation, the
  restore pass is.
