HP RDX Continuous Data Protection Software? Deduplication?

[Nuno Fonseca]

Does anyone know if this software backs up SQL Server / Exchange Online (VSS)?

How about Virtual Server 2005 Virtual Machines?

It does seem to backup the virtual hard disks (.vhd) But at 8 gb per .vhd version it will fill up the cartridge pretty quickly.

It appears to only do file deduplication, but I think I read it somewhere that it would do data(sector,chunk) deduplication.

Any ideas?
