Backing Up OS Data
If you want to operate the OS server on a newly installed PC following the software update,
we recommend you back up the OS project of the OS server.
By default, the configuration data and the archive data of the OS are stored in the OS project
of the OS server.
To back up data, compress the project paths in this folder. Save the backup on a suitable
medium.
