Its all a matter of using the "changetime", using the default time, it
shows the recoverables from the last known "incr" and previous "full",
using changetime and moving to a time before the Last known incremental
will show the information prior to the last known incr,, the rename, and
or deletion and will recover those files from that point in time.

When I started teaching NetWorker classes for Legato during the NW 4.x 
days, I had to verify for myself that deleted files weren't recovered 
during a browsable recovery and that renamed files were recovered only 
under their final name.  Sure enough, that is the way it worked, 
supposedly due to information stored in the CFI.  For many years the 
Legato admin course actually had a lab showing this behavior.

Yesterday I verified the same proper behavior is still there in NW 7.5.1

(Windows 2003 NW server) with the following test:

1.  Create a folder C:\Tester containing "file1", "file2", and
"deleted".
2.  Do a full backup of a test group containing a client whose save set 
list contains "C:\Tester".
3.  Delete "C:\Tester\deleted".
4.  Do an incremental backup of the test group.
5.  Rename "C:\Tester\file2" to "C:\Tester\renamed".
6.  Do another incremental backup of the test group.

Firing up NetWorker User and looking in "C:\Tester", the only files 
listed are "file1" and "renamed".  Thus, the deleted file is not 
recovered and the file that was renamed is recovered only under its 
final name.
