Interesting to note about the transfer of the full file after the 32
subfile backups - does this definitely happen?
You mention that 1GB was used as the subfile cache area...how big was the
amount of space available on the server?
I believe that the TSM client does not perform housekeeping on this
directory (i.e. it does not clean out old binary images) and you have to
do this yourself.
thanks,
Rowan.

AW: Subfile backups (or Adaptive Copy)
I tested it on couple of file servers, it worked like a breeze,
but at the last I was definitely limited by it´s limits
(grr, my wording in not worth to loose a word about)
namely subfile cache area - which is 1 GB as far as I can remember,
anyway, far too small to keep all delta files dictated by my file servers
in
question.
I ended in purchasing extra bandwidth and performing "regular" forever
incremental.
I still have got a very small client location where subfile backup
simply works and works - no troubles at all so far.
Another point to watch is that regulary,
I believe after each 32 subsequent subfile backups,
full file size will be transfered once again.

Betreff: Subfile backups (or Adaptive Copy)
All,
Have a customer looking at subfile backups for two webservers which are
hosted at a remote hosting facility and connected via a WAN.
We are looking at using subfile backups to enable these servers to
participate within the TSM hierarchy, but I want to get a feel of
real-world-experiences from people who are actually using it in production
at the moment.
What have been your main issues? (apart from the obvious being expanded
TSM processing time on the client, and slow restores).
Also, how have you sized the subfile cache area? Was there a rule of thumb
for this sizing?
thanks!
Rowan.
