2.5 Description of the actions
Archive and backup files larger than 4GB
If a backup is to be restored with "sc restore" - consisting of several archive files - only the
first file of the backup must be specified in the FILENAME parameter. Once the end of the
file has been reached, other parts will be searched automatically.
Decisive when determining the continuation files is the format of the file name which was
transferred during calling, i.e. when calling "sc restore /tmp/backup.01of02.tgz", and after
reaching the end of "/tmp/backup.01of02.tgz" the search is on for the next file
"/tmp/backup.02of02.tgz". When calling "sc restore /tmp/backup.1of2.tgz", file
"/tmp/backup.2of2.tgz is expected correspondingly as a second part of the backup.
Options
If no further options are specified, the archive should represent a full backup and this should
be restored in full. The status of all files is therefore the same after the "restore" as it was at
the time of the backup.

restart option can also be useful with -update. If user-defined system files are changed
when loading an archive, a restart or reinitialization is necessary. In such cases, "sc
restore" outputs a message to that effect at the end of the operation. The -restart option
causes the required action to be performed automatically.
