Abstract

This invention discloses a method to manage the multiple target data backup for mobile devices and to restore the latest backup data at the time of disaster. The timestamp is inserted among the write commands to identify the latest backup image from all the remote storage when restoring data. Reference count and other mechanism is introduced to do message queue management. This invention can provide the maximum data redundancy by copying data to different targets and ensure the minimum recovery point objective.

A method to manage multiple target backup for mobile device


1. BACKGROUND OF THE INVENTION

Along with the enterprise level usage of smart phones, more and more requirement emerges for the data protection and backup for mobile devices. Prompt data backup is essential to protect customer data against smart phone damage or other disaster situation. The current solution is to backup the data to cloud, personal computer or other storage server separately. One kind of configuration is to establish only one backup target. For this situation, if both the mobile device and the only target are broken, the data is unavailable. The other configuration is to configure more than one target, but the backup for each target runs separately. That impacts the efficiency of the backup. And it is hard to know which one is the latest image when the restoration is launched. A method is required to manage the data backup to multiple targets.

In the scenario that a user is using a smart phone to finish the daily job, the above situation is met. The user's input to the smart phone needs to be copied to the laptop via Wireless Fidelity immediately. And at the same time, the input is also copied to the storage server of the department for backup. And for the best data protection, the input is also archived in the private cloud of the company. In the future, this kind of disaster recovery solution for the mobile device will be more and more important. And the mechanism to support this configuration is necessary.


2. RELATED WORK/PRIOR ART

(1) Only backup the data to one target storage. It can only provide one backup. If both the mobile device and the backup are down, the data is lost.

(2) Backup the data to different target storage separately without management and coordination. It's hard to find the latest image to restore after the disaster occurs.


3. SUMMARY OF THE INVENTION

This invention discloses a method to manage the multiple target data backup for mobile devices and to restore the latest backup data at the time of disaster. The timestamp is inserted among the write commands to identify the latest backup image from all the remote storage when restoring data. Reference count and other mechanism is introduced to do message queue management.

Compared with current solution to backup to one target, this invention can provide the maximum data redundancy by keeping data to different targets. That can cover the situation of mobile device damage and one remote storage down. Compared with current solution to backup to different target separately, this invention can provide an easy way to resto...
