Online backup
Backing up and restoring the CPU configuration
You can back up a CPU configuration using the Web server with the corresponding access
rights. If necessary, you can also restore this configuration at a later time using the Web
server.
You can create as many backups as you want and store a variety of configurations for a
CPU.
NOTICE
Prior to every restoration of the CPU configuration, always first perform an online backup of
the current CPU configuration and save this backup file to a local directory of your PC.
This ensures that you can undo a restoration which failed (e.g. due to a damaged backup
file) or which does not show the desired result.
Note
You can also perform online backup and restoration of the CPU configuration in STEP 7 (see
STEP 7 online help, keyword: "Creating a backup of an S7 CPU").
When backing up using STEP 7, the backup file is saved within the STEP 7 project. With a
backup using the Web server, the backup file is saved to a local directory of your PG/PC
(e.g. "Downloads" directory). Web server backup files cannot be restored via STEP 7, nor
can STEP 7 backup files be restored directly using the web server.
To restore a STEP 7 backup file using the web server, first save the STEP 7 backup file to a
local directory of your programming device/PC (e.g. "Downloads" directory). From there, you
can restore the backup with the Web server.
Note
The "Online backup" function is not available if you access the web server via:
• a virtual IP address
• a communication module (CM)
• a communication processor (CP)
Requirements
● You access the CPU via the secure transmission protocol "HTTPS".
● A valid CA-signed certificate is installed in the Web browser; see section Configuring the
Web server (Page 19).
