BACKUP has the advantage over COPY that it's much faster and more reliable (Marty claims he hasn't had any problems restoring files from tape using BACKUP).
1) become SYSTEM on UCCDFN (need privs for image backups) 2) Put the second tape into tapedrive MKA400: $ INIT/OVER=EXPIR MKA400: BACK02 Take out the second tape and put first tape into tapedrive MKA400: $ INIT/OVER=EXPIR MKA400: BACKUP 3) $ MOUNT/FOREIGN MKA400: - mount vol. 1 4) Start an image backup of the whole disk with complete directory structure: $ BACKUP/NOASSIST/IMAGE/REWIND/LOG/IGNORE=INTERLOCK/RECORD - DKA300: MKA400:dka300.BCK,MKA400: - /BY_OWNER=ORIGINAL/SAVE_SET/LABEL=(BACKUP,BACK02) 5) After the first tape is full: The drive will open up. Take out the first tape and put the second tape BACK02 in. The backup job will automatically mount the second tape and then will continue to copy files. 6) When the backup is complete: $ DISMOUNT MKA400: To restore a file, mount the first tape (even if the file is on the second tape) and use the command $ BACKUP/REWIND/LOG - MKA400:DKA300.BCK/SAVE_SET/SELECT=[DATA.CDF.ANA]myfile.ext;* - UCCDFN$DKA300:[DATA.CDF.ANA]myfile.ext/BY_OWNER=ORIGINAL/NEW_VERSION This will restore the file on disk with a higher version number. If the file is on the second tape, put in the first tape and wait until the job has gone through it and the drive opens up. Then put in the second tape.
