Provided is a method for data backup. The method includes: A, receiving the data type of data in need of backup selected by a user; B, calculating the capacity 1 of data the type of which is the same as the data type, and detecting the user residual capacity 2 of a server end, comparing the capacity 1 with the capacity 2, and if the capacity 1 exceeds the capacity 2, interrupting the backup process, and if it does not exceed said capacity, executing step C; and C, encrypting and uploading the data in need of backup to a database of the server end for backing up, and displaying the backup result after the backup is finished. The present invention can directly back up important data to a server end via a mobile terminal, which can not only occupy less storage space of a local mobile terminal, but can also effectively protect important data from going missing, greatly satisfying the security requirements of users. |
