Why is the transfer rate slow in Google Drive Windows Server 2008 r2?

Question

Google Drive

Good day everyone. I've been struggling with this problem for more than a day now.
There is Windows Server 2008 r2 on board the 1C base, which must be constantly backed up to Google Drive, moreover, so that the penultimate copy remains. Of course, you can do without third-party software using the task scheduler + command line, but the problem remains with the speed and through the Google Drive application.
In general, I found a couple of adequate programs that fit the given requests: Iperius Backup and @MAX SyncUp .
MAX SyncUp has an excellent transfer speed to Google drive, but some settings are not to my liking. But Iperius Backup suits everything, moreover, it works as a service, encrypts, etc., but the average transfer speed is 125 kb / s on the server. On my computer (Windows 8.1), the transfer speed from Iperius Backup to Google Drive is excellent.
Do not tell me what could be the problem? Is it possible that some service is missing for the server, or vice versa, something needs to be disabled? (Firewall and firewall are disabled)
ps : Download speed to Google drive via browser is high 4-5 mb/sec.
