International Classification:

G06F 17/30

US Classification:

707626, 707635, 707809

Abstract:

Systems and methods for synchronizing data between endpoints, including the modification of data on an endpoint without necessarily modifying data that is communicated between endpoints are disclosed. In such systems and methods the representation of data on an endpoint may be modified so that constraints on that particular endpoint are enforced, without requiring a similar or the same modification to the data when it is synchronized to other endpoints.

International Classification:

G06F 7/00

US Classification:

707691, 707802, 707829

Abstract:

Generally, the described system and process enables resolution of conflicts in a synchronized folder. Within the described mesh operating environment, each of the devices may be configured to do the same processing so that the file system view of the synchronized folder looks the same on all devices (pending local capabilities). Updates that cannot be immediately realized to the local store due to conflicts may be deferred for later attempts when, for example, additional updates at the system level or local level are made to resolve or eliminate the conflict for the update item. Generally, further changes may be propagated by a user in addressing a particular conflict that the user is notified about (e. g. , via a selected winner that the user disagrees with). Alternatively, the conflict may resolve itself when a further update occurs that overrides or renders moot the previous update (e. g.

US Classification:

707610, 707614, 707620, 707622, 707624

Abstract:

The claimed subject matter is directed to a file system watcher in the presence of different file systems to allow synchronization of replicated files distributed among different file systems without compromising the features of each file system. To synchronize the distributed replications, a platform independent synchronization manager creates a file system watcher for each file system associated with a replication of the file. The file system watcher monitors each object for events affecting the object or the object's constituent files, such as creation, deletion, change and rename. Notifications are sent to the synchronization manager, which consolidates the modifications and updates a locally stored replication, if necessary. The synchronization manager then sends a notification of an update to all other synchronization managers for all replications of the distributed file or folder. Synchronization is complete when the nonconforming synchronization managers acquire a replication of the locally stored replication and update their respective objects to conform therewith.

International Classification:

G06F 15/16

US Classification:

709217, 707710, 370503

Abstract:

Systems and methods for synchronizing data between endpoints using elements of centralized and decentralized synchronization systems and communication topologies are disclosed. Such systems and methods may in some cases synchronize some subset of data with a centralized endpoint while another subset of data is synchronized in a decentralized fashion directly with other endpoints. Such systems and methods may include a variety of cooperative functionality to assist in the synchronization of data between endpoints.

Appl. No.:

Inventors:

Richard Y. Chung - Redmond WA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 7/00

US Classification:

707634

Abstract:

A method for synchronizing files is provided. Current metadata including a filename and a hash identifier for each file of the synchronized folder is created. The current metadata is compared to previous metadata. Based on the comparison, a first file and a first folder added to the synchronized folder and a second file and a second folder deleted from the synchronized folder are identified. The hash identifiers of the first and second files are compared. If the hash identifiers match, the filenames of the first and second files are compared. If the filenames do not match, the first file is identified as a renamed file. Metadata is sent to a synchronized device with information related to the first folder sent before information related to the first file, which is sent before information related to the second folder.
