To my opinion this looks a bit like what I'm looking for.
At the moment I have an Imac that is wireless connected to a 2TB time capsule (TC1).
To this time capsule I have another 2TB time capsule (TC2) connected via a upt wire connection.
At the moment there is a backup made via time machine from the Imac to the time capsule TC1 (the second TC is not used)
I'm not so technical so I hope you understand the configuration.
What do I want to achieve :
copy all my data from the Imac to TC1 so that the information can be accessed by more users.
create an automatic backup from TC1 to TC2 (mirror or raid system) for security.
give access to some users on the network to access TC1 to read and write data.
TC2 only serves as backup from TC1 and no direct access is needed to this disk.
If there is a solution, thanks for explaining it in 'IT kindergarden style' so that I can understand and use the info.
Many thanks in advance.
