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 the media database (SQL).
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 (Levels 2 and 3) the media file system program,
metadata, and journal files are on the D: drive. Also the media database program
and data files are 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 Storage Systems (Levels 2R and 3R), 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 and data files are on the
D: drive, but the data files are replicated to the redundant server. 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 restore the data files
(metadata, journal, database) from their protected locations elsewhere.
• 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
