SYSTEM@CRNLNS.BITNET.UUCP (03/12/87)
Just to add my two-cents-worth to the discussion, our Backup strategy is to do a /IMAGE/RECORD Backup weekly while the system is available for general use (NOT standalone). We do time-shared incrementals (/MODIFIED/SINCE=BACKUP) every night. The following commands are extracted from our backup command file: $ input := SYS$SYSDEVICE: $ output := BKP:ALLSAV/SAVE/REWIND/BUFFER=5/DENSITY='P1' $ BACKUP/image/FAST/RECORD/IGNORE:INTERLOCK- /jou=USER$DISK:[backup]SYS_'WKLNAM' 'input' 'output' I have successfully rebuilt a system disk from such /IMAGE tapes, without a lot of effort: I had to run ANA/DISK/REPAIR an odd number of times, but that's all. While it is true that files open at the time of the Backup won't be properly restored, that is a small loss compared to what would otherwise be the case. I hope this helps. Selden E.
