About the recovery disk image process
On the K2 Media Server, there are three partitions on the system drive to support
backup and recovery strategies as follows:
• The C: drive is for the Windows operating system and applications.
• The D: drive is for the media file system (SNFS) and database. This allows you to
restore the Windows operating system on the C: drive, yet keep the files on the D:
drive intact. You can also restore the D: drive itself, however your backup and
recovery strategy is different for non-redundant and redundant systems, as follows:
• On non-redundant servers the media file system program, metadata, and journal
files are on the D: drive. Also the media database program is on the D: drive.
Therefore if you ever have a D: drive fault and you need to recover the data files
(metadata, journal, and database), you can only restore them to the “snap-shot”
contained in the most recent disk image you created. When you do this you
restore the program files as well.
• For redundant K2 SANs, the media file system program is on the D: drive, but
the metadata and journal files are stored on the shared RAID storage. Also the
media database program is on the D: drive, but the database data files are stored
on the shared RAID storage. Therefore, if you ever have a D: drive fault, you
can restore the media file system and database programs from a recovery disk
image, and then access the data files (metadata, journal, database) from the
shared RAID storage.
• The E: drive is for storing a system image of the other partitions. From the E: drive
you can restore images to the C: and D: drives.
When you receive a K2 Media Server from the factory, the machine has a generic
image on the E: drive. This image is not specific to the individual machine. It is
generic for all machines of that type.
You receive a recovery CD with your K2 Media Server. This recovery CD does not
contain a disk image. Rather, the recovery CD is bootable and contains the Acronis
True Image software necessary to create and restore a disk image. You also receive a
similar recovery CD for K2 Media Clients, but it is specifically for the desktop
Windows operating system (Windows XP), rather than for the server Windows
