The present technology is directed to providing a multi-root architecture for managing devices associated with their own root namespaces. The system can include backing up multiple computing devices to a single user account such that the content items from each computing device are stored in their own respective root namespace at the user account. With each user account having multiple root namespaces, the system can identify which root namespace is receiving changes, identify which changes are necessary to synchronize the system, and then communicate those changes to the content management system. This process is facilitated by running a synchronization engine for each root namespace, thereby controlling synchronization for each root namespace. Each synchronization engine is able to retain its own parameters of operation, which provides the ability to tailor synchronization modes on each synchronization engine.

Implementing different synchronization processes using a multi-root system

The present technology is directed to providing a backup service utilizing a bi-directional synchronization architecture. In order to support both a backup service and a bi-directional synchronization service, the present technology can utilize a special object called an anchor that only permits unidirectional synchronization. Additionally, the present technology separates the backup service from the bi-directional synchronization service. This separation includes utilizing a separate backup directory and bi-directional synchronization directory on a client device, which in turn benefits from the use of a separate instance of the synchronization service on the client device. Further, at the content management system various steps are taken to separate the backup directory from the bi-directional synchronization directory to ensure no objects from the backup directory appear in a user interface related to bi-directional synchronization, and vice versa.

Backup feature provided by bidirectional synchronized content management system

Technologies for implementing customized behaviors for content items are provided. An example method can include receiving, from a user account registered with a content management system, a request to access a content item managed by the content management system for the user account, the content item having one or more behaviors configured for an attribute associated with the content item and/or the content item associated with the attribute; obtaining, from a representation of a remote state of content items associated with the user account, metadata defining the attribute associated with the content item; based on the metadata, determining the one or more behaviors configured for the attribute and/or the content item associated with the attribute; and applying the one or more behaviors to the content item.

Per-node metadata for custom node behaviors across platforms

The present disclosure is directed toward systems, methods, and non-transitory computer-readable media for generating, managing, and restoring data backups for user account data at network-based third-party systems. For example, the disclosed systems generate data backups within a content management system to store user account data from third-party systems such as social media systems, photo library systems, video sharing systems, and others. In some cases, the disclosed systems detect changes to data a third-party system and further updates a stored data backup corresponding to the third-party system based on the detected changes.

Storing and restoring user account data backups across online platforms

The present technology pertains to synchronizing contents of a directory external to a synchronized directory by a content management system. The content management system is configured to synchronize only objects in the synchronized directory. Accordingly, the present technology creates an anchor object that represents the directory external to the synchronized directory within the synchronized directory. The anchor object includes special attributes that indicate to the synchronization client that the anchor object represents an external directory, and allows the contents of that directory to be synchronized directly to a server on the content management system without first storing the contents of the external directory on the hard drive of the client device.
