A saga of woe. My scheduled backups on the 1st of the month failed, which is to say dump dumped, but restore claimed the dumps were not dump tapes. I also tried a backup tape from 3 months ago, same issue. Sometimes, on the third or fourth attempt, restore will read the tape, then fail on the next attempt.
Weird errors like:
So this is what I did with no improvement after each step:
1) clean the drive (twice);
2) replace the 6 month old tape with a brand new one;
3) replace the SCSI cable;
4) replace the SCSI host adapter card;
5) replace the tape drive with a brand new one;
6) recompile the operating system from the current RELENG_7 sources;
7) upgrade from 7.4-PRERELEASE to 8.2-RC1 (via CDROM and source).
8) the current 8.2-RC3 is compiling as I type, but I'm not hopeful.
[Edit: 8.2-PRERELEASE, same issue

Hardware
========
Motherboard: Gigabyte GA-M720-US3, Phenom 9550, 4Gb DDR2
SCSI host adapters: Adaptec 2940U2W (first) 29160 (second)
Tape drives: HP StorageWorks DAT72 Tape Autoloader (first) Seagate DDS4 (second)
Hard drives: 2x WDC WD5000AAKS-00A7B2 SATA 500Gb
Video card: GeForce GT 220 PCI-E
PSU: Antec Truepower Trio 550 watt
The last time it worked (1 January) it was using an ASUS A8V motherboard and FreeBSD 7.1-STABLE which was a temporary measure until I bought a new Phenom-capable motherboard because the previous Gigabyte motherboard went up in flames after the video card failed, the motherboard copper tracks superheated and the varnish caught fire.
Apart from the tape problems, the system had been running without any issues for the last 26 days.
Any ideas?
