Storage constrained synchronization engine
First Claim
1. A method comprising:
- receiving, by a client device, an updated file journal entry from a content management system, the updated file journal entry including an updated namespace ID of a content item stored by the content management system;
comparing the updated file journal entry to a plurality of local entries in a local file journal stored by the client device to identify a shadow item on the client device, the shadow item replicating metadata attributes of the content item without storing actual content data of the content item stored by the content management system, wherein the shadow item includes at least a namespace ID of the content item;
updating the identified shadow item by replacing the namespace ID of the shadow item with the updated namespace ID; and
replacing a local file journal entry corresponding to the shadow item with the updated file journal entry.

Abstract
A content management system synchronizes content items across client computing systems connected by a network. If a storage allocation for shared content items on a client device is exceeded by the request to add or edit a content item such that it is enlarged, a client application or the host of content management system selects content items to remove from residence on the client device but keep remotely on content management system. Upon removal of the selected content items, the client application creates shadow items, representing the content item but only containing the metadata of the content item. This creates sufficient space while maintaining user access to all synchronized shared content items. Entries in a file journal may be used to track and manage whether a stored item is a content item or a shadow item.

15. A system comprising:
-
one or more processors, and a non-transitory computer-readable storage medium storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising; receiving, by a client device, an updated file journal entry from a content management system, the updated file journal entry including an updated namespace ID of a content item stored by the content management system; comparing the updated file journal entry to a plurality of local entries in a local file journal stored by the client device to identify a shadow item on the client device, the shadow item replicating metadata attributes of the content item without storing actual content data of the content item stored by the content management system, wherein the shadow item includes at least a namespace ID of the content item; updating the identified shadow item by replacing the namespace ID of the shadow item with the updated namespace ID; and replacing a local file journal entry corresponding to the shadow item with the updated file journal entry. - View Dependent Claims (16, 17, 18, 19, 20)
