Backup/Restore – Restore
When restoring the job files from an archive, the
archived files will replace the existing files of the current
job.
Warning: If you do not want to lose any new data that
was collected after the archive being restored was
created, you should first backup the current job to a new
archive before restoring an older archive.
< Back : will return to the previous screen.
Restore : will restore the backed up job from the
selected archive. The current job is then deleted and
replaced by the backup job.
