$! BACKUP_SERVER.COM
$! Remote tape service via DECnet

$! on tapeless system use:
$!
$!      $ BACKUP somefiles -
$!        SOMENODE"system password"::"TASK=BACKUP_SERVER" -
$!        /BLOCK=16384 /SAVE
$!----------------------------------
$ Set NoOn
$ Set RMS /Network=32 ! 32*512=16384, largest record
$ Alloc MUA3: TAPE
$ Mount /NoAssist /Over=ID /Block=16384 TAPE
$ Convert /Stat SYS$NET TAPE:Remote.BCK /FDL=SYS$INPUT
$DECK
RECORD
