Registry Optimization for Windows 7 Backup Server

Date October 7, 2018 Author By kadmin Category General, Windows 7

Problem:

I’m using Windows 7 as a storage server for my Acronis backups.  I frequently get failed backups due to SMB connections failing.

Solution:

Open Windows registry (Windows + R -> regedit.exe) and set HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\LargeSystemCache to ‘1’. This key tells Windows to set aside enough system cache for sharing large files.

Then set HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters\Size  to ‘3’. This value tells Windows to prioritize file sharing over reducing memory usage. You can read more about this key here.

Reboot (or just restart the “Server” service in services.msc). The problem should now be solved.
