3.3 NEARLINE MANAGEMENT
XT clips can be sent to the nearline for backup purpose. They are saved on the
nearline as files. Nearline files are on-line when the physical storage where they
reside is still accessible. Nearline files become off-line when the physical storage
is no more accessible, e.g. IP drive (or XF drive) removed from the hardware.
However, off-line nearline files are still listed in the Database Explorer for easy
retrieval purpose.
A clip which only contains a nearline file can be restored to XT, for example for
playout purpose.
Once a nearline directory has been configured in the Remote Installer, the
IPDirector will continuously scan the directory path looking for new files or files
being deleted. The IPDrive service will also automatically detect the appearance
of a new IP drive, or XFile disk, or the ejection of a drive.
3.3.1 F
ILES
T
YPES
All the files appearing on the nearline storage are filtered according to a list of
supported extensions. Depending on the extension, they will or will not be visible
in IPDirector.
Files can be classified among three types:
1. files with a non-supported extension and which are not video files: they
will be ignored and will not be visible in IPDirector.
This could be an EVS XML file without an associated A/V file or this could be a
file with a non-supported extension like a dll, or a text file.
2. A/V files with an extension not supported on the nearline: they will be
visible in the Media Files branch of the tree, but no clip will be created, so
they will not be visible in the Clips branch of the tree for most users.
