If "sc save" is used directly on the control, and the subsystems are running, this can lead to
inconsistencies between saved files because they could still change during the backup
process. Therefore, in this case "sc save" exits with the message that subsystems are still
running. If you want to create a backup anyway, you can use the -force option. The message
to the subsystems is still output; however, the backup operation still continues.
If "sc save" is started from the service system, assuredly no subsystems of the control are
running and "-force" is not necessary.
Archiving and backup files larger than 4 GB
If the backup is written to an FAT32 target file system, which does not permit any file size
greater than 4 GB, the backup is divided into several files, each of which is smaller than this
threshold value.
In the target file name that is specified when "sc save" is called, in this case, details of which
part of a backup is involved and the total number of associated files are provided: Calling "sc
save /tmp/backup.tgz" thus generates, for example, the "/tmp/backup.01of02.tgz" and "/tmp/
backup.02of02.tgz" files.
2.5.16 save-nvram (data backup)
Description
Syntax:
Alternative names:
Authorization level:
Using command "sc set-nvram", the content is saved to a non-volatile memory (non-volatile
memory). Depending on the machine type and equipping, such an NVRAM is provided in the
integrated drive, in the PLC and as TCO-EEPROM.
Using options -drive, -plc and -tco, individual NVRAM types can also be explicitly selected for
backup. Backing up all existing types is the default setting.
The content is written to files called "nvram-TYP.bin"; whereby, TYP is replaced by "drive",
"plc", .... The files are created in the current directory if no directory is specified.
