why do you require to backup ost files?
Its better to backup the Exchange database, because the *.ost files only have an offline copy of the user's data.
If you delete the *.ost file, it should be automatically recreated by Outlook downloading the Data from the exchange database.
As said.. no one backup OST file. we only backup PST file or exchange database.

You need to create a logoff script and set it to copy the file to a network share.
Here is an example:

@echo off
set backupcmd=xcopy /c /d /e /h /r /y

echo Backing up OST settings...
%backupcmd% "%USERPROFILE%\Local Settings\ Application Data\ Microsoft\ Outlook\*.*" "UNC path to your share"

Here are some help full links:

If you copy .ost file on an other computer, you will not be able to read it in Outlook ! You will need an external product to convert .ost to .pst

Sorry I am not clear.
Only the OWNER of the .ost file can open the .ost file and he needs to be the OWNER of the Exchange mailbox (and to have a current connexion to the AD) http://support.microsoft.com/kb/831058/en-us?fr=1
I never try that, but I already study to open .ost another domain, and we don't succeed (it was a need for a migration)
Of course you can use an external tool to read ost. There are a lot of tools on Internet, backup pst/ost tools, repair pst/ost tools or online services that are able to do the job

The better tool to recover .pst file if Outlook Advanced Repair, so I can recommend Advanced Exchange Recovery to manage .ost file from the same editor
