The reviews for Riverbed are positive from all sides. The solution they provide looks very promising. In the test trial, we found that it addressed all the issues that we were facing, especially sharing large graphic and design files.

Looking forward to get these products in, in the coming time.

There are some unsupported ways to backup the vault using standard enterprise backup tools but you need to be careful as to how you go about this - the biggest concerns are:

 
1) Do not backup the SQL database when it's live
2) And make sure to test your disaster recovery scenarios

My preference is to expend time on the front end [creating the backup], rather than on the back end.

Acronis True Image Echo Workstation creates an exact disk image of your office desktop and allows you to backup key data files and folders. You can run backup jobs on multiple machines simultaneously on both 64-bit Windows and 32-bit Windows systems with the centralized remote management capabilities.

Are you using 10 / 100 hardware & cabling or gigabit hardware & cabling?

                     

Is the data stored on the computer with the fastest CPU, most ram, and fastest hard disk drives? If not, that could be part of your problem.

 

Have you evaluated the network for load balancing?

 

A router that utilizes SPI (Stateful Packet Inspection), a firewall based protocol, can reduce network efficiency.

Actually we need to implement an incremental or a differential backup procedure. And that too in multiple locations.

It sounds like something might not be configured quite right. Since one of my partners had recently copied ~200GB to a fresh (empty) usb drive and it didn't take anywhere near as long. I was surprised to hear that. Now, I am trying to re-configure.
