This happened to me in the past; DEC technical support provided the
answer.  What you need to do is set various parameters higher specifically
for standalone backup, depending on how much memory you have.  Change the
appropriate device names and numeric values as appropriate for your system
and you should be able to do the backup successfully.

>>> B/E0000001 DKA400:

SYSBOOT> SHOW VIRTUALPAGECNT
SYSBOOT> SET VIRTUALPAGECNT 100000
SYSBOOT> SHOW PQL_DPGFLQUOTA
SYSBOOT> SET PQL_DPGFLQUOTA 32768
SYSBOOT> CONTINUE

Alternately, you can set things more permanently from DCL so that you
wouldn't have to do the manual procedure above each time you did a
standalone backup:

$ MCR SYSGEN
SYSGEN>  USE USER7:[SYS0.SYSEXE]VAXVMSSYS.PAR
SYSGEN>  SHOW VIRTUALPAGECNT
SYSGEN>  SET VIRTUALPAGECNT 100000
SYSGEN>  SHOW PQL_DPGFLQUOTA
SYSGEN>  SET PQL_DPGFLQUOTA 32768
SYSGEN>  WRITE USER7:[SYS0.SYSEXE]VAXVMSSYS.PAR
SYSGEN>  EXIT

Good luck.
