listed.  You should therefore be able to delete from top of the list
down to the first file that wasn't restore.  =20
In practice I actually leave in both the last partially restored file
and the one above it - I then remove those from the restored files -
I've seen issues where even though the file above the partially restored
one appears to have been completely recovered it has caused issues if I
don't delete it too.
Your resulting list(s) should only be those files that are NOT on the
target.

4) Start a bprestore using the list created above.  (Start a separate
one for each list if there is more than one.)
bprestore -R <changefile> -L <restorelog> -C <client source of the
backup> -D <client dest of the backup> -S <NBU master> -s MM/DD/CCYY
hh:mm -e MM/DD/CCYY -f <filename>
Where changefile is a file you use for renaming the files if restoring
to an alternate path - not necessary if you're restoring to original
location.  You would first have to create change file to use it.
Restorelog overrides default log location - not required.
-D destination not required if your restoring to original client.
Filename =3D the list file you created above.

Good Evening,=20


You can generate a list of files to restore in a file and pass that file
as input to the netbackup restore command.

I believe this feature as listed below is basically the tsm -ifnewer
option .=20

I wonder if the netbackup folks would accept this new feature requrest.

Possible, yes.  Not sure how easy or efficient it would be.

All the information needed to make that decision can be found from
bplist/bpflist (both can show mtime from file at time of backup) and by
scanning the actual filesystem.  You could have a script look at the
catalog and the filesystem and create a list of files that you want to
restore, and make the restore overwrite unconditionally.

That part seems reasonable, but parsing the stuff from the catalog would
take a bit of work.  The thing I don't know is how well NBU would deal
at the end with a restore request and a file listing with *lots* of
files.  Assuming that part is fine, this is doable.

Good luck!
