Sometimes, when you have to copy a very large file for example a DB backup which is over 60GBytes you may encounter an error stating:

Operating system error 1450 Insufficient system resources exist to complete the requested service.


ERROR 1130: Not enough server storage is available to process this command.


Backup or restore operation terminating abnormally.

Microsoft KB describing this issue is here.

In our case following steps described in Registry fix 1 solved the issue.

Fix consists of adding DWORD value named PoolUsageMaximum a and setting the value to 60 as initial one. Unfortunately server restart is required after adding this, so keep this in mind.

Above fix did the job. I have tested it with Robocopy.exe and Richcopy with logging enabled and all seems to be working fine.
