1. A computer-implemented method performed by one or more processors for backing up files, the method comprising the following operations:
initiating a backup operation of a plurality of related files; determining a first file in the plurality of related files was modified prior to executing the backup operation on the first file; executing the backup operation on the modified first file to generate a backed-up file of the modified first file; determining the backed-up file of the modified first file includes data inconsistent with data in a backed-up file of a second file in the plurality of related files, wherein the determination includes comparing data in the backed-up file of the modified first file with related data in the backed-up file of the second file; and replacing the backed-up file of the modified first file with a version of the first file that existed prior to the modified first file.
