Abstract

Techniques for managing a file system involve in response to receiving, at a first backup device of the file system, a request for replicating data of the file system from the first backup device to a second backup device of the file system, determining a synchronization state between the first backup device and the file system, the second backup device being a backup device located downstream of the first backup device; creating, based on the synchronization state, a target snapshot associated with the file system; and causing the data to be replicated from the first backup device to the second backup device based on the target snapshot. Therefore, the data backup flexibility and accuracy of a file system can be significantly improved and therefore the reliability of the whole system may be enhanced.
