BACKUP and /SINCE, extra files?

» close window

The Question is:

 
OpenVMS V6.2-1H3
 
Having problem with incremental backup.
 
Some files are incrementally backed up as per expectations while other files
are not.
 
Example: directory listing of two separate files
 
Directory DKA0:[UCX$FTP]
 
LOGIN.COM;1                   File ID:  (7169,1,0)

Now consider the following incremental backup commands and their
corresponding results...
 
 
 
OAK> show time

OAK>
OAK> backup/record/fast DKA0:[UCX$FTP]login.com;*/since=backup
dka300:[backtest]dka0.bck/save/label=test
%BACKUP-W-NOFILES, no files selected from DKA0:[UCX$FTP]LOGIN.COM;*
%BACKUP-I-STARTRECORD, starting backup date recording pass
%BACKUP-W-NONEREC, no files processed on recording pass
OAK>
OAK> backup/record/fast DKA0:[UCX$POP]login.com;*/since=backup
dka300:[backtest]dka0.bck/save/label=test
%BACKUP-I-STARTRECORD, starting backup date recording pass

Here are the directory listings for the respective directory locations...

Can you shed any light on this anomolous behaviour?
 
Thanks, James R. Gibson.
 
 

The Answer is :

 
  Curious.  Please acquire and install the current BACKUP ECO kit,
  and then -- if the problem persists -- please contact the Compaq
  Customer Support Center.
 
  This might be an unusual manifestation of a change made to BACKUP
  at V6.2, to ensure that an incremental restoration will work -- in
  this case, the parent directory DKA0:[UCX$POP] has never been backed
  up, and may be triggering the BACKUP operation.  (Reset the BACKUP
  date on the parent directory (via Freeware DFU tool) or via a pass
  of BACKUP with /RECORD, and try the test again.)  Various previous
  discussions of BACKUP and apparent extra file selections are here,
  as well.
