I am afraid I have not found any documentation specific to Cache databases, either, and we have requirement to back them up, too.
We are just in the process of migrating from TSM to Avamar for all our AIX systems. The scheme we are planning to use for Cache databases is to:
1) Execute a script we wrote to
a) pause the Cache database on HostA,
b) split off a Symmetrix clone
c) un-pause the Cache database on HostA.
d) mount the AIX filesystems on a sepate AIX host (HostB).
2) A short while later the Avamar schedule will run on HostB which will back up all mounted filesystems.
3) A later script unmounts the cloned filesystems, resetting things for the next day. (This script actually gets called the next day, just before Step 1).
One thing we are concerned about is that the size of the Cache databases is so large, and there are so many of them, that the backup will take a long time. From my limited knowledge of Avamar, it seems like the client backs things up in a single-threaded mode. It seems to me that if it could run 6-8 threads simultaneously to back up separate filesystems at once, it would get done much faster.
If you have any thoughts on this, let me know and we can exchange ideas about this.
Yea I stumbled upon it after looking around. Thanks for the response though – greatly appreciated. I am completely new to Avamar. We are converting from Symantec Netbackup to Avamar. I’m sure I’ll be posting more questions as we get rolling.

For multithreaded backup, find attached document for solaris which should help as process should be similar for AIX..
Thanks and Regards,

I you have installed demo Avamar server, than you have document on Avamar server - Avamar backup clients user guide.pdf
In that guide you can find how to install and configure AIX clients .....
