"Delayed Write Failed" sbs 2003 during veritas backup exec 10.d burn to dvd + windows event id 50 & 26
Posted on 2006-11-02
The Breakdown: I'm trying to backup my SBS 2003 server using Veritas Backup Exec via burning to dvd. Primary purpose is to backup our SQL database. The requirements for Veritas is that the disk must be formatted with a 3rd party software. (Nero incd 188.8.131.52) Because of this the disks must be dvd-+rw.
Hardware: AMD 3200 on an Asus nForce4 motherboard, NEC cd/dvd/rw, 2 gigs memory, 2 200 gig Seagate drives in raid mirror, disks Memorex dvd+rw 4x and Verbatim dvd+rw 2x. all of the cables are correct for dma, I’ve tried 2 identical dvd roms, same issue.
My process: When I put in a new dvd it must be formatted using Nero incd. Then I do the backup using Veritas backup exec witch you cannot control the speed of the burn(frustrating). The first time I run backup exec on a disk their is not any errors. Its only after the dvd is formatted and run Veritas again that the errors pop up. I've tried erasing the disk & full format with verify it makes no difference how many times you format the disk it still shoots out errors.
If i watch the windows event viewer while backup exec is running, it repeatedly produces event id 50 and event id 26. Approximately 30 times during the backup. Warning incdfs event 50. Information application popup event 26 Delayed Write failed
The errors that Veritas produces reads something like, Veritas job failed to complete backup-to-disk folder 1. the data from the media is inconsistent 0xe0084ca. & Verify an inconsistency was encountered on the storage media v-79-57344-33994 event id 34113
Things I’ve tried: disabling the verify during the Veritas burn will produce no errors. Also backing up everything but "sbs monitoring" "sharepoint" "tmsql" <name of server, causes no errors. So its wonderful that I cant back up the things most important to us. Not the way I want to roll. I do have the latest greatest updates for SBS, Veritas, Nero and drivers for the hardware.
Things I’m not willing to try: disabling dma mode on the dvd rom. that’s just stupid, the most common thing people so far have recommended. Here is why, it take about 8 hours to burn a dvd without dma, and it pegs the cpu the entire time, rendering the server useless. no one can access it with only 1 percent of the cpu available. Also I don’t want to through out my dvd's after each backup, they are rewriteable, and I want to rewrite to them. If I cant find a solution I’m going to install a backup to tape device.
Please, any and all solutions are appreciated, if you need further information, I will try and fill in the gaps.
