We have about 15 OS X desktop machines - mainly iMacs, some MacBooks and Mac Pros. Each user has a local account on the machine, and a portable USB disk for a Time Machine backup.
I want to coordinate the backups to a central NAS, and I'm thinking about something like the Synology DS2411+ (I know there are only 12 bays; we may need 2 of them!), allocating one disk each for each client machine.
Our network hardware is gigabit capable, and all clients connect at 1000baseT. I'm concerned about the network utilisation. I know the initial full backup will take a long time, but I'm prepared to do that one machine at a time overnight. But what about when multiple clients do their incremental TM backups at the same time? What kind of impact could that have on the network?
Is this a feasible network based solution? Are there alternatives?
