  • Patent number: 11025718
    Abstract: Enterprise administrators in a cloud-based environment including a cloud-based server and a repository can selectively impose permissions on items (e.g., files and folders) marked for synchronization (“sync items”). The sync items can be synchronized with the client devices of users by downloading the items along with the permission attributes from the cloud-based server. However, the permissions on those sync items means that any unpermitted changes to the local copies of the sync items do not get uploaded to the cloud-based server. A synchronization client on the client devices detects any changes made locally to the sync items that are not consistent with the permission attributes, and repairs those changes so that the sync items are restored to their most recent states. This ensures that any unauthorized changes made to sync items remain local and do not propagate by the synchronization process to other users.
