A method of backing up a file comprises synchronizing a first file to be backed up and a second file which is a copy of the first file to contain the same contents; monitoring a file close process of the first file in a read/write mode, and when the file close process is detected, locking the first file and stopping synchronization of the first file and the second file, and unlocking the first file thereafter; creating a third file which is a copy of the second file; and resuming the synchronization of the first file and the second file.
