Unless there was a change recently, TSM does not send a full after 32 subfile backups.
See http://msgs.adsm.org/cgi-bin/get/adsm0208/898.html for when a new base file is sent.

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.

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. regards juraj salak -----Ursprüngliche Nachricht----- Von: Rowan O'Donoghue [mailto:[EMAIL PROTECTED] Gesendet: Dienstag, 14. Oktober 2003 17:31 An: [EMAIL PROTECTED] 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. ForwardSourceID:NT00019F26
