Time Machine wireless backup

[cheef]

Hello fellow Apple peeps. I have a query, and I'm wondering whether any of you have spotted the answer whilst on your internet travels.

I have an iMac in "Room A", with a 2TB external disk connected via firewire 800. My iMac backs up to this disk quite nicely via Time Machine using the standard Backups.backupdb folder structure. The iMac is connected to a gigabit wired network.

Also in Room A, I have a Mac mini which is also connected to the same wired network, and backs up to the 2TB disk connected to the iMac over the LAN. This uses the <mac_name>.sparsebundle format.

In Room B, which is on another floor and doesn't have a wired network facility, is a second Mac mini. This mini is connected to my network via a 5GHz wireless network.

I want the mini from Room B to back up to the same 2TB disk (connected to iMac) using Time Machine, over the wireless network.


Achievable?


Thanks in advance.

Thanks for the replies, folks.

PardonTheWait:

Can you expand?


Skyboat:

If I connect to the 2TB disk (on the iMac) from the mini in Room B, it'll show up as a connected server no problem. I use the Time Machine preferences to select the disk, which it does, but when I try to do a backup I get this error...

... so it doesn't look as plain sailing as I first thought - unless you mean there is something different I should be doing?


sbi5ar:

Can't have another external disk in Room B I'm afraid, it's in a bed room and I don't want any further noise. As 'silent' as the mini is, there's still a small 'hum' and I don't want to add to that. Your "wirelessly and wired" statement has triggered something that I'm going to try.

Remove the mini from Room B and connect it to the router. Select the backup disk via the iMac and let it backup, to first create that sparsebundle. I'm hoping that when taken back into Room B and connected via wireless, it'll see the previously created sparsebundle and backup the increments to it over wifi.

Worth a shot, anyway.


Thanks for the suggestions thus far.
