backup via the UNIX client with a language compliant backup application. Mixing
languages (example: having a Japanese UNIX server and a Chinese backup
application) will lead to data corruption. If you do not have language compliant
backup applications, do not back up using UNIX.
Backing Up Using Unicode-Enabled MacOS Clients
Macintosh text encoding UTF8 is supported by MacOS 10.1.4 AFP 3 and later. For
Unicode to function properly, your version of MacOS must fully support AFP 3.
It is important to back up via the MacOS client with a language compliant backup
application. Mixing languages (example: having Russian files on a server, then
using a German backup application) will lead to data corruption.
Unicode and Expansion Arrays
This section outlines how Snap Server expansion arrays interact with Unicode.
Unicode Converted Expansion Arrays
When an expansion array is converted to Unicode, it stays converted to Unicode.
This means that a Unicode enabled expansion array is only compatable with head
units that have also been converted to Unicode.
The following is a usage scenario concerning expansion arrays and how they
operate with Unicode enabled servers.
You have a Snap Server and an expansion array such as a SANbloc S50. You
enable
Unicode on both. You cannot then attach the S50 to a non-Unicode-enabled Snap
Server.
The Unicode-enabled expansion unit will not be seen by a non-Unicode
enabled server.
Once an expansion array has been converted to Unicode, it cannot be used with
non-Unicode enabled Snap Servers.
Unicode Converted Head Units
When a Snap Server is converted to Unicode, it stays converted to Unicode. If a non-
Unicode expansion array is attached to a Unicode-converted Snap Server, the
expansion array will be automatically converted to Unicode when it is incorporated
with the Snap Server.
Caution
Converting to Unicode is a one-way operation. There is no undoing the
conversion to Unicode if you change your mind.
