A method, article of manufacture, and apparatus for synchronizing mobile device data in a mobile device network is disclosed. In some embodiments, this includes using a processor to identify server data, first comparing the server data with a first mobile device data, and updating the server data based on the first comparison. In some embodiments, the updated server data may be compared (second comparison) to a second mobile device. The second mobile device may be updated based on the second comparison.

Mobile device network data synchronization

A method for information management comprises intercepting an output from an application; distributing packets according to a routing scheme, wherein the packets are associated with the output, and wherein distributing the packets may occur when the application is associated with a first operating system, and may also occur when the application is associated with a second operating system; and storing the packets.

Versatile information management

A method, article of manufacture, and apparatus for recovering mobile device data is disclosed. In some embodiments, this includes using a processor to access a server with a unique identifier, determining data to be recovered from the server to a target mobile device, transmitting the determined data to the target mobile device, and storing the transmitted data on the target mobile device. The determined data may come from a source mobile device, and the determined data may be recovered to a target mobile device or multiple target mobile devices.

Mobile device data recovery

Searching data is disclosed. A searchable index is used to determine which, if any, data objects comprising a set of backup data are responsive to a search query. For the search query, a search result is generated. The search result includes, in the event a first data object that is responsive to the search query comprises a version of one or more other data objects that are responsive to the search query, data indicating that the first data object comprises a version of said one or more other data objects.

Data object search and retrieval

Information management is disclosed. A file output from an application to an operating system is intercepted before the file output arrives at the operating system. The file output is directed towards protected data. The intercepted file output is analyzed to determine whether a predetermined type of version of the protected data has been created. In the event it is determined that the predetermined type of version of the protected data has been created at least in part because the analyzed intercepted file output includes a modification to the protected data, the protected data automatically backed up, including by storing at least a portion of the file output as a backup version of the protected data. In the event it is determined that the predetermined type of version of the protected data has not been created, the protected data is not backed up.

Backup information management

A method, article of manufacture, and apparatus for sharing data between a plurality of mobile devices is disclosed. In some embodiments, this includes using a processor to associate a first mobile device with a mobile device group, associating a second mobile device with the mobile device group, allowing the second mobile device to access the first mobile device data based on the association of the second mobile device with the mobile device group, and storing the association of the second mobile device with the mobile device group in a storage device.

Mobile device group-based data sharing

A method, article of manufacture, and apparatus for backing up mobile device data is disclosed. In some embodiments, this includes using a processor to identify a mobile device, creating a snapshot of the mobile device, and storing the created snapshot in a server. In some embodiments, the snapshot includes all of the mobile device data. In some embodiments, the snapshot includes a portion of the mobile device data.

Mobile device snapshot backup

A method, article of manufacture, and apparatus for optimizing resource use in a mobile device network is disclosed. In some embodiments, this includes using a processor to store mobile device data on a server, creating server metadata based on the stored mobile device data, storing the server metadata in a mobile device cache, and using the mobile device to access the server metadata stored in the mobile device cache.

Cache-based mobile device network resource optimization

A method for information management comprises monitoring output from an application to an operating system, wherein the output is monitored substantially continuously; determining if a policy applies to data associated with the output; and executing the policy if the policy applies.

Information management

A method, article of manufacture, and apparatus for protecting mobile device data is disclosed. In some embodiments, this includes determining mobile device data to be stored on a server, accessing the server with a unique identifier, transmitting the determined mobile device to the server, and storing the transmitted mobile device on the server. Accessing the server with a unique identifier may include providing verification to the server, such as a password. Transmitting the determined mobile device data may include transmitting the determined mobile device data through a wireless connection.

Mobile device data protection

Changes are tracked by tracking a change request which when performed by a disk driver changes a portion of disk storage. The change request is allowed to pass to the disk driver to be performed by the disk driver. Information associated with the change request is stored in an operating system's persistent storage. A differential backup is performed using the information associated with the change request stored in the operating system's persistent storage after a system, which includes the disk driver and the disk storage, has shut down and restarted.

Write interceptor for tracking changes to a disk image

A technique for quiescing a file system is described. The technique includes holding a change request, flushing the file system, and releasing the change request. Flushing may include sending a flush request, determining whether a cache associated with the file system is flushed, and in the event that the cache is not flushed, resending the flush request and determining whether the cache is flushed.

File system quiescing driver

In one embodiment, a method for information management comprises monitoring output from an application, wherein the output is monitored substantially continuously; determining if the output is associated with a predetermined type of version; and saving data associated with the output if the output is associated with the predetermined type of version.

According to some embodiments, a technique for tracking changes to a disk image is disclosed. The technique comprises tracking a change request associated with a disk block; allowing the change request to pass to a disk driver; and associating the change request with an operating system's persistent storage.
