Workflow (Restore via XML File)
1. An external system (which can generate XML files for restoring clips, for
example MediaXChange) sends to XT Access an XML file to request the
restore (copy) of clips from an archiving or backup system to a given XT
server.
2. XT Access processes the XML file:
a. It gets the clip file to restore from the external system.
b. It restores, i.e. copies, the clip on the XT server specified in the
XML file.
Workflow (Restore via Folder Scan)
1. Based on the parameters defined in XT Access, this application scans
specific folders on external backup or archiving systems.
2. When a clip file has been completed written to the scanned folder, XT
Access creates a copy of the clip on the XT server specified in the XT
Access parameters.
The restored clip receives a new UmID and LSM ID:
o Multicam assigns automatically a UmID to the restored clip.
o A start LSM ID is specified in XT Access and incremented as
defined for each new clip that is restored in order to find an empty
location on the XT server.
The restored clip contains the clip metadata.
3. The restored clip is moved from the scanned folder to one of the
following subfolders on the external archiving or backup system:
o \Restore.done\: folder where the files are moved to when they are
successfully restored.
o \Restore.error\: folder where files are moved to when they failed to
restore.
