Question : SBS Backup failed on D: "The system cannot find the path specified."

Backups are partially failing nightly at 8:30pm on a SBS 2003 SP2 server with all updates installed.  I get this error below:

Warning: Unable to open "D:\" - skipped.
Reason: The system cannot find the path specified.

Searching for this error pointed me here:

It sugests creating a batch file that runs NTBackup to check for permission errors, but I'm not sure how to read the output.
Here's the batch file:

@echo off
echo %date% %time% Start of task > c:\test.log
echo User=%UserName%, Path=%path% >> c:\test.log
dir d:\ 1>>c:\test.log 2>c:\test.err
md d:\Test 1>>c:\test.log 2>>c:\test.err
echo %date% %time% 1>d:\Test\WriteTest.txt 2>>c:\test.err
%SystemRoot%\system32tbackup.exe /.. /.. /.. 1>>c:\test.log
echo %date% %time% End of task >> c:\test.log

This is the output I get:

Can someone interpret this & tell me if permissions are set correctly?
I've checked the event logs but don't see any specific error.  The only anomaly I see is in the backup log with the error above.

Answer : SBS Backup failed on D: "The system cannot find the path specified."

The PS4000X is a pure SAN (it only does iSCSI over Ethernet) while the NX4 is a 'unified' system, and has the potential to replace not only your existing SAN but also your NAS/file servers as you can host shares on it. The NX4 also supports fibre channel if you ever wanted to move in that direction.

Other than the hardware differences, the management interface is where you spend 99% of your time and of the two products I would go for the Equallogic. EMC has taken its mid-90's interface (and thinking) and sqaushed it into a new system so its awkward to do stuff that should be easy.

If you could, I would go for a NetApp, one of the smaller FAS2020 or FAS2040 models. THese will gove you everything that your current 2 choices give, but also has ASIS (deduplicaton) meaning you save if you deploy virtual machines or many files with similar data (think Word and Powerpoint document metadata etc). THese saving alone can cancel out the slightly higher cost of the product, and the management interface is acutally really good.
