NT Backup fails to run sporadically W2K3-R2

January 9, 2008

I have a strange problem with a server that I recently upgraded

(installed from scratch - NOT in-place upgrade) from Windows 2000

server to Windows 2003-R3(SP2) server

I use NTBackup for nightly tape backup and sometimes it just doesn't

run at all. There doesn't *seem* to be a pattern. There's no error

mesage - it just doesn't run. BUT - if I run it manually it never

fails.

Here's the relevant hardware config:

.. IBM 226 Server

.. AIC7902B Ultra 320 SCSI

.. Sony AIT 50 GB SCSI Drive on Bus Number 0, Target ID 0, LUN 0 -

Driver version is "1.0.0.4" (31/08/2004)

My backup batch file is

rsm refresh /lf"Sony AIT 50 GB SCSI Drive"

c:\batch\Sleep 30

C:\WINDOWS\system32\ntbackup.exe backup "@C:\Documents and Settings

\Administrator.DOMAIN\Local Settings\Application Data\Microsoft

\Windows NT\NTBackup\data\backup.bks" /n "Backup Media" /d "Backup

Set" /v:no /r:no /rs:no /hc:on /m normal /j "server1" /l:s /p "8mm

AIT1" /um

Note:....

rsm refresh /lf"Sony AIT 50 GB SCSI Drive" sometimes displays:

No match was found for the friendly name supplied.

Unable to convert library friendly name to guid.

Even though....

RSM VIEW /TLIBRARY always shows:

Off-line Media

HL-DT-ST CD-ROM GCR-8482B

Sony AIT 50 GB SCSI Drive

I just need to guarantee that backup will run reliably overnight. Any

suggestions?
