Method used to back up data on the USG6000
The methods used for backing up configuration content and restoring the configuration are as follows: 1. Back up and restore profiles using the FTP, SFTP, and TFTP servers (recommended). This method is applicable to the situation in which a large number of devices are maintained in a centralized manner. 2. If the device serves as an FTP server, you can configure the FTP server function for configuration backup and restoration without configuring FTP software. Open FTP ports cause certain potential security risks. 3. Back up the profiles on the storage server. The operation is simple and does not require other software. If the data is backed up on the same storage media, the primary and backup profiles may be damaged simultaneously. 4. The configuration data backup and restoration on the web UI is simple. You need to configure the web login in advance.
