Abstract
The present invention proposes a method for doubly backing up files asynchronously, wherein at least two first network elements share a second network element, both of said first network elements include respectively an active file handling device and a standby file handling device, characterized in that, said active file handling device copies the files to the second network element, if said standby file handling device finds that said active file handling device misses the files, said standby file handling device copies backups of the files to said active file handling device, thus the files stored in said active file handling device and the files stored in said standby file handling device being synchronized.
