Could not find a part of the path "T:\Pranas.NET\SBS"

Hi,

Update: Using a LUN/ISCSI Disk Mount worked as a temporary storage location. Curious why Mapped Drive does not work though?

I am testing a trial of the software and have tested a few scenarios all working pretty well. However, I am running into an issue with a test database. The database is around 100GB.

This worker machine does not have enough Temporary Storage for this particular job.

For the “Temporary Folder” I first attempted to use UNC path \\192.168.88.195\TempStorage, but quickly found out it didn’t like that (plus I could not enter creds here).

So, then I mapped a drive against the letter T:\ in Windows. Which has 600GB free, more than the 25GB currently free on the Windows machine.

I get an error saying

Could not find a part of the path 'T:\Pranas.NET\SBF\50518a1b-95ad-4044-9dc9-8d74c5e5aec4\backup

I also notice that the application seems to report “” for free space on T, which isn’t accurate. So maybe that’s where it fails? Since it unable to tell the amount of free space it just fails?

5e5aec4\backup" has "" free space.

I think my next option is going to attempt to mount an ISCSI LUN to this machine. Would love to know if anyone else has seen this before or anyone’s thoughts.

Hello,

Thanks for your message.

The issue is that the application runs as a Windows service under the Local System account, which does not have access to drives mapped in a user session.

That’s why it fails to recognize the mapped drive and reports no free space.
