Backup Exec 2010 / WAN Accelerator

Hello,

Running into a de-duplication issue using Backup Exec 2010 and a Silverpeak NX 2600 WAN Accelerator.

Apparently, our Silverpeak device is not able to de-dupe the Backup Exec data because they are claiming the data is compressed.

I double checked the backup job settings and verified that compression was set to NONE.

My question is, does Backup Exec natively compress data even though the setting is turned off?

Basically, Backup Exec is  sending the data from a server at our main branch to a NAS at our remote branch over the WAN. We have a channel bonded T1 and we only getting 19MB transfer speeds.

I also wasn't sure if Symantec would go through enough trouble to make it where their data counldn't be de-duped unless you purchased thier de-dupe solution...

Any help here would be appreciated.
Thanks,

It could be the way it's writing the data to disk.  I would do a 60 day eval on the deduplication feature and see if it improves throughput.

Bonded T1s are 1.5Mbps each = 3Mbps = 380kbps..keep in mind 2 T1s are 3 in bits, divide by to get bytes.

19MB? Is that per second, minute..?  Let's baseline the throughput first

Also, it depends on the files you are testing.   If you send a .zip file, for instance, then it is already compressed, regardless of what BE does to the file.  So were the files that you are benchmarking raw text files which are highly compressible or .zip, .gz, or other compressed formatted files.
