A test that safeguards the integrity of the program failed unexpectedly

I backup sbs2003 std with besr 2010. The backup is done to a local sata disk attached to the computer (devided to 9.4 gb files), and then copied to a NAS. Base recovery point weekly, and daily incrementals. Usually, it is working OK. Once a week, usually in the 5th incremental, the backup fails with this message. When I kill the vprotray.exe, resart the BESR service, start the vprotray again and start a new recovery set - it works OK, for a 4-5 days only... and then fails again.

You might try not to devide the backup files. In our case it was the solution to a similar problem.
