I have a question regarding the "File Copy" functionality in veeam and specifically if its possible to tweak the behavior of the process that is doing the copy work.
As it is now when we copy backup data (large files) the proxy servers we copy between use up all its RAM (windows file cache) and it would be beneficial to be able to inactivate the caching.
When running for example robocopy its possible to specify options to not use the windows cache.
And even specify how many threads the copy should use.
These settings increase copy performance quite a bit in some cases.
From robocopys command line parameters:
/J :: copy using unbuffered I/O (recommended for large files).
/MT[:n] :: Do multi-threaded copies with n threads (default .
n must be at least 1 and not greater than 128.
This option is incompatible with the /IPG and /EFSRAW options.
Redirect output using /LOG option for better performance.

No, its not possible to tweak File Copy functionality.
Also, keep in mind that historically speaking, this functionality was created and optimized for data transfers to and from vSphere datastore. Just as you mentioned, there are plenty of existing tools which can provide high-performance file copy between Windows systems - it was not our goal to create yet another one.
