The same happened to me and the strangest part is i could compile the kernel, and do all the memory tests just fine, as you i also had new ram so after changing lots of things like network cards, removing hardware and so one i changed the ram (the ones that all the tests said it was fine) and voilá... it started working like a charm.
The curious is it just stopped working while doing the backups, I manage several hosts ones with tar, other with rsync and some others with samba.
I think the memory would only stop if working under stress for a long time (as the kernel compilation does) but with the kernel compilation maybe it wasn't long enough. As backuppc uses compression, encryption and high IO for a long time it probably stresses the computer more than the kernel compilation.

Probably the same is happening to you.
Cheers,
Pedro
