By default, the remote cache synchronizes specific software to reduce the amount of packages and updates that are transferred from the CommServe cache. The remote cache synchronizes the following software:
- 
Updates required for all the clients associated with the remote cache. 
- 
Packages required to upgrade associated clients that are from older Commvault versions. For example, if you have a V10 client, then the remote cache retrieves V10 updates along with V11 packages and updates needed to upgrade the client. 
You can adjust the synchronization settings of a remote cache to perform one of the following operations:
- 
Synchronize additional packages for specific operating systems, in addition to the packages that are automatically synchronized. This is useful if you plan to install new packages in the near future. 
- 
Synchronize all packages and updates that reside in the CommServe cache.
