That's what I also thought first.
But what he wants is to replace the files that have changed after the last
backup with the latest backed up version... :-)
Of course he could do a PIT restore but that would result in much more
database processing on the TSM server because the server would have to look
for every eligible file for that system and not only the ones that changed
after the last backup.
It's like saying "Search at Google" or providing the exact URL. The results
will (probably :-)) be the same but the first way takes longer.
Mit freundlichen Grüßen,
Met vriendelijke groeten,
With best regards,
Bien amicalement,

This "problem" sounds impossible,,, kinda like an "Ann Landers" test(?).
If you want to restore file that changed AFTER the latest backup, by
definition, it has not been backed up, yet! I suspect, like other
respondents, that you are really looking for point-in-time restore...
I worked with a customer situation where a drive failure occurred "slowly",
such that the admin's failed to prevent normal-daily-incr from running
after hundreds of thousands of files got vaporized, though the drive was
still operating; the net was to research the logs for the last successful
(and full/good) daily incremental, selecting the date-time of completion
for the PIT parameters.

Hello,
Someone wants to restore only the files which have changed after the latest
backup.
The opposite of the -ifnewer option on the restore command, in other words
doing an "incremental restore".
There are possible ways of doing this, like for instance for a unix client:
touch -t some_time_stamp some_ref_file
find -newer some_ref_file > files_to_restore
for each if the files in files_to_restore dsmc restore .....
Are there any other possibilities, preferrably using standard TSM
mechanisms ?
Xavier Merlin
