Varian,
Adaptive differencing is targeted for remote clients where network bandwidth
is in Kbytes and everyday backup is approximately 100 MB's. TSM client has
extensions which first time sends whole file and it uses few metrics and
stores them at client side. Second day backup of file is differentiated at
send to server. Server consolidates files in delta form and it stores base
file plus delta. When you do restore client pulls both files into staging
area and assembles into one file. If you have 10/100/1000 Ethernet, don't
consider using this technology. It's disadvantages are: More processing
power is required. Staging area needs to designated atleast of 10% of file
system size.
Thank you,

Subject: Adaptive Differencing
Can anyone give me a better explanation of how Adaptive Differencing
actually works with existing filespaces and volumes. Going by the White
Paper I downloaded it sounds like it wants you to make a full new backup
when you turn on Sub-File Differencing. Also if you use this on your local
LAN have you seen marked performance improvements? Or is it more beneficial
only in a dial up environment?
Thanks,
Varian Greenwale
