To create a proper system disk image backup under V6.2, it is necessary to issue the BACKUP command with the /NOALIAS qualifier.  BACKUP/IMAGE without the /NOALIAS qualifier does not pick up the VMS$COMMON directory or its contents.

These commands properly copy and restore the VMS$COMMON directory under VMS 6.2.

Image Backup Command

$ BACKUP/IMAGE/NOALIAS/IGNORE=INTERLOCK DKA0: MKA600:SYSTEM.BCK/SAVE

Image Restore Command

$ BACKUP/IMAGE MKA600:SYSTEM.BCK/SAVE DKB0:
