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 an EVS video server,
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 IP drive service will also automatically detect the appearance
of a new IP drive, or XFile disk, or the ejection of a drive.
