The XFile is equipped with 2 removable media, working as mirrored drives:
each clip is automatically saved as 2 separate files on these drives. This
provides a security copy in case of drive failure, and also gives the
possibility to send these 2 drives to 2 different locations/studios after the
show. Each removable media has a capacity of 500GB or 32 hours of
footage at standard bit-rate. More XFile stations can be inserted on the
network if more archive copies are required.
The XFile can also be used as a security backup of the network: should
one server lose its footage for any reason (accidental delete for instance),
clips can be restored from the XFile to any other server (XT6U, XT4U or
AirBox) on the network.
All Super-motion clips, created on any networked LSM-XT, are stored by
XFile amongst the normal files. The 75 fps nature of such material is
maintained during archiving and is restored in a single pass without
alteration. Therefore, restored Super-motion clips can be re-used as
Super-motion footage (playback at 33%) or as a standard material
(variable speed) just as if they where captured from the super-motion
camera just now.
The combination of XT4U, XT6U, AirBox and XFile, all interconnected on
XNet, forms the basic architecture required to move from a mostly tape-
based production to a disk-based environment.
