We do TIR backups wherever possible (Win9x and Mac clients do not
support it). We also have many big servers with many small files on
them.
I personally think that a backup software that doesn't have a restore to
a point-in-time option is not worth the effort, for exactly the kind of
cases you just had. NBU's TIR restore of a large directory takes time -
especially in the beginning, until it gets all the information for the
actual restore: TIR info is usually kept on tapes (we were told that
otherwise the backup database becomes too large), but still - it is much
faster and more efficient than any other way you can restore a large
directory to a certain date.
More than that: we discovered that when you restore a whole Novell
volume with a regular restore - the file rights are not restored
correctly, while restoring it with TIR - puts all the original file
permissions back.
