Method, system and device for acquiring directionally published microblog messages are disclosed. A first client acquires an instruction for reading a microblog message from a first user, wherein the instruction comprises a keyword of the first user; the first client extracts directionally published microblog messages matching with the keyword of the first user from an outbox of a second user, wherein the second user is followed the first user and has a directional publishing authority; and the first terminal displays the extracted directionally published microblog messages to the first user. Through the solutions provided the present disclosure, a first user only needs to access an outbox of a second user for acquiring a microblog message, and thus the first user does not need to delete the microblog message. The operation of the first user is simplified, and thereby the user experience will be improved.

A method and a system for data migration are described, the method for data migration including: slicing data in an original system to obtain a data slice; importing the data slice into a new system; and redoing, in the new system, respective data corresponding to at least one pre-recorded write request according to a sequence number order of the at least one pre-recorded write request, wherein the at least one pre-recorded write request above is to simultaneously write to both the original system and the new system. In the method and the system, data in an original system can be seamlessly imported to a new system without forbidding writes to the original system, and the data in the new system can be recovered to the latest by a redo technique. Without any awareness of users, the data migration can be achieved in the background.

A data synchronization method is provided. The data synchronization method includes providing a first server with a master flag and a write flag for a data block; providing a second server; and importing a snapshot of the data block to the second server. The method further includes configuring a synchronizing flag for the data block on the second server; synchronizing, by a synchronizing component, data of the data block on the first server to the second server; and removing the write flag of the data block on the first server when the data block is to be migrated out of the first server. The method also includes synchronizing, by the synchronizing component, latest data of the data block on the first server to the second server; removing the master flag of the data block on the first server and removing the synchronizing flag of the data block on the second server after data of the data block on the second server and the data of the data block on the first server are completely synchronized; and configuring a master flag and a write flag for the data block on the second server.
