I have the latest build and I'm using modern hardware, nothing funky. TI 10, Windows XP Pro SP2, Dell P670, CERC SATA software RAID, 150GB Raptors, Intel Pro 1000. Get the same error part way through backup: Failed to write data to the archive file. A possible reason might be poor media quality. I've tried backing up the several different machines, all running reasonably current hardware/software. All fail with the same error. No problems backing up to local hard disk. Apparently this is a catch-all, but gives you nothing in terms of troubleshooting. Any ideas? TIA.
