Changes are synced in the background every 120 minutes, by default, but synchronization is configurable by using the Configure Background Sync Group Policy setting.

Some specific applications include: Starting with Windows 8 and Windows Server 2012, administrators can configure the experience for users of Offline Files to always work offline, even when they are connected through a high-speed network connection.
Windows updates files in the Offline Files cache by synchronizing hourly in the background, by default.
You can now designate a set of computers, known as primary computers, for each domain user, which enables you to control which computers use Folder Redirection, Roaming User Profiles, or both.
Designating primary computers is a simple and powerful method to associate user data and settings with particular computers or devices, simplify administrator oversight, improve data security, and help protect user profiles from corruption.
There are four major benefits to designating primary computers for users: For more information, see Deploy Primary Computers for Folder Redirection and Roaming User Profiles Folder Redirection, Offline Files, and Roaming User Profiles require an x64-based or x86-based computer, and they are not supported by Windows on ARM (WOA)-based computers.
With Always Offline mode, computers never transition to Online mode when the Configure slow-link mode Group Policy setting is configured and the Latency threshold parameter is set to 1 millisecond.
As of the November 2013 Windows 8.1 update there is now a registry key you can set to spawn a .v3 profile to avoid conflicts with older versions of the profile.
This registry key is a DWORD Value called “HKEY_LOCAL_MACHINE\System\Current Controlset\Services\Prof Svc\Parameters key.

Prior to Windows 8 and Windows Server 2012, users who wanted to minimize fees while using Offline Files on metered network connections had to track their data usage by using tools from the mobile network provider.
