The most important thing to do on a client with so many files is to make sure that the file cache is sized appropriately. The file cache is responsible for the vast majority (>90%) of the performance of the Avamar client. If there's a file cache miss, the client has to go and thrash your disk for a while chunking up a file that may already be on the server.

So how to tune the file cache size?

The file cache starts at 22MB in size and doubles in size each time it grows. Each file on a client will use 44 bytes of space in the file cache (two SHA-1 hashes consuming 20 bytes each and 4 bytes of metadata). For 25 million files, the client will generate just over 1GB of cache data.

You must use the backup agents to backup Exchange and SQL. Databases on Image level backups will not be consistent.

To backup the environments, you would need to do a guest level backup. i.e. Install the avamar agent, and the exchange VSS plugin on the Exchange server, and the SQL plugin on the sql server.

If you want to backup the OS, ensure you create windows datasets to skip the database files on the server, otherwise you'll be backing up database files that look totally different each time (consuming huge amounts of space on the grid), that will be no good to you (they'll be inconsistent)!

Besides the above points, the Exchange VSS plugin has some fairly useful functionality, like being able to backup databases in parrallel, and being able to do granular level restores (i'm still trying to get this to work).

Well worth using.
