Can I back up multiple Mac OSX systems to a single rsync.net account ?
Yes. You can set up backups on one or more systems, all of which can store them in a single rsync.net account. Most of the time a network of multiple Mac OSX systems is first backed up, locally, to a central server (perhaps a file server or departmental server) then rsync jobs are run from that central file server, backing up all of the data in one transaction. You can, of course, simply run rsync jobs from each individual workstation. Or you can have some combination of clients and servers. It is completely up to you, and we are happy to help you implement a strategy that fits your needs.
