Sorry if I'm  wrong on this. But from what I have seen and admin guide

"

Avamar processes these dataset elements in the following order:

1. Source data — Source data from one or more plug-ins is defined. The default behavior

is to include all data from all defined plug-ins.

2. Exclusion list — Next, the exclusion list is used to eliminate certain directories and file

types from the dataset.

3. Inclusion list — Finally, the inclusion list is used to add back any files that were

eliminated from the dataset in the exclusion list. "

So i believe with Windows File System you could exclude

"Drive Letter":\*      <- excludes everthing

Include  "Drive Letter":\*\ABC\

Thank you Jhiciano. We have tried using "Drive Letter":\*\ABC\, seems like Avamar will only use "Drive Letter":\*\ABC\ and not "Drive Letter":\*\*\ABC\ or "Drive Letter":\*\*\*\ABC\. Basically, we need Avamar to back up any folder on any location on the drives named ABC. We'll try your suggestion as well, seems legit.

I havent tried this before but the logic seems right, that *\ABC\ should work and no drive letter and that will search for everything

from what I read ( don't remember where I read it)

**\ABC  is what you want

that ** is supposed to mean anywhere in the tree - that is what I have in my head anyway.

Give that a try.

Try also **/ABC .  I had to do something similar and ended up with d:/**/logs/*.*

Hope that helps
