Embodiment Construction

[0040] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0041] Such as figure 1 As shown, the server side synchronizes the virtual disk to the client side.

[0042] 1. The server notifies the client of the name of the disk to be synchronized this time, the size of each synchronized data block (len) and the method of calculating the checksum (default md5);

[0043] 2. The server reads a data block from the starting position of the virtual disk, and the server sends the starting position of the data to the client;

[0044] 3. Calculate the checksum on the server side;

[0045] 4. The client reads the data according to the starting position and length;

[0046] 5. The client calculates the checksum;

[0047] 6. The client sends the checksum to the server;

[0048] 7. The server side compares the local checksum with the client data checksum;

[0049] If the result is the same, go back to step 1 and continu...

Abstract

The present invention discloses a virtual offline desktop block device storage synchronization method. The method comprises the following steps: a synchronizing side reading virtual disk data, and sending a starting position and length information of the data to a synchronized side; the synchronizing side calculating a check sum; the synchronized side reading the virtual disk data according to the received starting position of the data, and calculating the check sum; and the synchronized side sending the calculated check sum to the synchronizing side, and the synchronizing side comparing a self-calculated check sum with the received check sum, if the check sums are different, sending the disk data, if the check sums are the same, taking no action, and if the synchronized side receives the disk data, writing the data into a local virtual disk. In the present invention, a block-by-comparison method is adopted, a next data block cannot be processed before completion of comparison and synchronization of the current data block, and once a failure occurs, a problem can be more quickly positioned in an operation on the data block compared with comparing multiple data blocks by the method, thereby further investigating a cause of the problem.

Description

technical field [0001] The invention relates to a storage synchronization method for a virtualized offline desktop block device. Background technique [0002] Desktop virtualization is to virtualize the terminal system (also called desktop) of a computer to achieve the security and flexibility of desktop use. Our personal desktop system can be accessed through the network at any place and any time through any device. [0003] Desktop virtualization relies on server virtualization. Server virtualization is performed on servers in the data center to generate a large number of independent desktop operating systems (virtual machines or virtual desktops) and send them to terminal devices according to a proprietary virtual desktop protocol. The user terminal logs in to the virtual host through Ethernet, and only needs to remember the user name, password and gateway information, and can access its own desktop system through the network anytime and anywhere, thereby realizing singl...
