Run WinZip to decompress the backup archive – it will produce a file with a “.tar”
extension.

Run WinZip again on the file created with the “.tar” file name extension. Use WinZip
to extract the specific file or files you require.
This technique will only work if the backup was not encrypted. Encrypted backup
archives must be restored using the Magnia SG20 software.
Using the second disk drive
The Magnia SG20 can be purchased with either one or two drives. These drives are the
only user serviceable parts in the system. If you purchased a server with a single drive,
you can purchase a second drive from Toshiba at a later time to upgrade your system.
Primary disk drive usage
Your primary disk drive has a size of 15 GB or more (depending on the configuration
purchased). However, not all of this space is usable for general file storage. Several
hundred megabytes are set aside and used for system files and other requirements to
support the various features of the server. The remaining space is available for you to
use as general file storage.
Secondary disk drive usage
A second disk drive can be used in two different ways, depending on your network
needs.
❖
A second disk drive can be configured to contain periodic snapshots of your primary
disk drive.
This snapshot mechanism makes a complete copy of the entire primary disk drive
on a periodic basis. If something goes wrong with your primary disk drive, you can
move the secondary disk drive in to the primary disk drive’s slot, reboot the server,
and the system will resume operation with all files intact as of the last time a
snapshot was taken.
You can specify when you would like to take a snapshot of the system. The process
of copying all files from one disk drive to the other can have an effect on server
NOTE: This process is commonly referred to as mirroring.
However, it should not be confused with RAID mirroring, where all files are
constantly mirrored on a second disk drive, which can significantly affect
performance.
