media as it exists on your media disks at that moment in time. Ongoing media
access alters these references, so to recover your media you need to routinely
backup your Media File System, as explained in the next point.
• Media File System backup — Refer to “Backing up the media file system” on
page 63 . This creates a file that contains all the references to the media currently
on the media disks. It contains all the database records that define your clips and
all the file system metadata that organizes the data on the media disks.
You should back up the Media File System whenever you do service work on your
iVDR, especially when it involves restoring from a software recovery disk image
or using the Storage Utility. You should also back up the Media File system on a
regular basis to allow partial recovery of your media in case of a major fault, such
as a system drive failure. However, keep in mind that any clips that are new or have
been modified since your last Media File System backup can not be recovered.
• Configuration backup — Refer to the M-Series User Manual for instructions on
using Configuration Manager to save a configuration file. This is a file in XML
format that contains all the current configuration settings as managed by
Configuration Manager. This file can be loaded into Configuration Manager and
saved to the database as a means to restore all settings at once. The default
configuration file is part of the software recovery disk image.
• Media backup — There is no built-in mechanism in the iVDR for backing up the
media itself. The media files in total can become very large, so if you need to back
up your media you should establish a mechanism that is suited to your facility and
its resources. You can stream media to another iVDR or Profile XP Media Platform
or export media files to a network server or removable media, i.e. USB drive, DVD,
etc.. Refer to the M-Series User Manual for instructions.
It is recommended that you place backup files (not media backup) on the second
partition on the iVDR system drive. That way they are readily available for your
service work. You can further enhance the security of these files by copying them to
a location outside the iVDR, such as to a network drive, CD-RW media, or DVD-RW
media.
Replacing an iVDR
To correct some system faults Grass Valley Support sends you a replacement iVDR.
The replacement iVDR is shipped with no media drives so that you can re-use the
media drives from the faulty iVDR. In some cases you can even keep the media that
is stored on the drives intact so that it can be saved and used on the replacement iVDR.
Read the explanations at the beginning of the following procedures and use the
appropriate procedure for replacing your iVDR.
Replacing an iVDR with saved media
If you want to save media and configurations, read the following explanation and
procedure. If you do not need to save the media and configurations currently on the
faulty iVDR, work though
“Replacing an iVDR without saved media” on page 49 .
