How do I write a BACKUP saveset to a remote tape?
How to do this correctly was described at DECUS long ago. On the OpenVMS host with the tape drive, create the following SAVE-SET.FDL file: RECORD FORMAT fixed SIZE 8192 Then create BACKUP_SERVER.COM: $ ! $ ! BACKUP_SERVER.COM – provide remote tape service for BACKUP. $ ! $ set noon $ set rms/network=16 $ allocate mka500 tapedev $ mount/nounload/over:id/block=8192/assist tapedev $ convert/fdl=SAVE-SET sys$net tapedev:save-set. $ dismount/unload tapedev $ stop/id=0 On the node where you want to do the backup, use the DCL command: $ backup – srcfilespec – node”user pwd”::”task=backup_server”/block=8192/save 5-56 System Management Information One area which does not function here is the volume switch; multi-reel or multi-cartridge savesets. Since the tape is being written through DECnet and RMS and the magtape ACP, BACKUP won’t see the media switch and will split an XOR group across the reel boundary. BACKUP might well be willing to read such a multi- reel or multi-cartridge saveset (direc
