Hello, Long time reader first time poster here and I need some advice. I travel a lot worldwide and just purchased a Cisco ASA 5505 firewall to setup at my house so I can VPN in to retrieve data. I'm looking for some sort of NAS solution in which I can VPN in and access the drive and do my time machine backups on. I want to ensure that I have RAID 1 as a solution or if it's one drive at least be able to backup the other via an external USB/Firewire method. Quick ASCII Diagram: Multiple Remote User --> VPN back into home --> NAS/Server for file storage and time machine backups (preferable to also have the option of having folders with access to own personal folders on the NAS device). Must be accessible via ethernet. I was looking at the Guardian Maximus but I'm not sure if that will get the job done. I was also wondering if I can add an external Hard Drive via USB and clone/copy the contents of time capsule itself on there? Thanks for your time and help.
