Anybody here using a Raspberry Pi as the "brains" of a Time Machine backup?

I've been fiddling with one over the weekend, the notional plan is to put it on our network and have my Mac and my wife's Mac automatically back up to partitions on a large external drive connected to the Pi. Worked my way through several online guides, but haven't quite cracked the code yet, and was curious if anybody here had gotten that setup working.

I haven't used my Raspberry Pi to do this, but I've done basically the same thing using a NetBSD system. I followed the instructions I found on the Web for setting up a Linux machine to serve as a Time Machine backup. Overall it basically worked about 95% of the time. Every once and a while it would choke and I'd have to manually do repairs either running Disk Utility or in some cases nuking it and restarting.

Finally decided I'd experimented enough and just plugged in an external USB disk to my Mac and that's been running fine as a Time Machine backup for almost a year now.

An upcoming experiment though will be to see if I can use the USB disk as a Time Machine backup when it's attached to my Asus RT-AC3200 router. The router has some logic that allows it to configure the disk as a Time Machine backup which should make it available to all my Macs for backup. It also has logic that allows me to configure my own personal cloud and I want to see if I can do both that and the TM backup at the same time on the same disk farm.

I wonder if I can use my son's Kano computer to do that...

Using a old Mac for server duties. Chronosync from each Mac to the server. Then Crashplan (have to look for new service this year, I guess) for offsite backup from the server.

Also feeds AppleTV from iTunes for music.

And TimeMachine from one drive on server Mac to other driver on server Mac.

No doubt. He's probably already done it.

Wireless or wired?

Would it just be eaiser to just put a large USB or NAS drive off the router/switch?

Theres really no need to partition the drive, TM doesnt care, fwiw.

I don't mean to disappoint, but... The Raspberry Pi isn't, in my opinion, a good choice for use as a NAS or Time Machine backup drive. The network interfaces top out at 100Mb are connected to the USB 2.0 bus, as would be the hard drive. This gives a theoretical max of about 12MB/sec. I've not seen real world benchmarks above around 6MB/sec, though it should be possible.

A simple NAS should easily trounce those numbers.

Whatever you do, look up "Pi-Hole" as a potential use of the Pi.

Well sure, but I already have the 8TB drive, adding the Pi was $30. If all us old deal-mac-ers are anything, it's cheap.

(I'll go wired, and it's good to hear from ya again, Grimmy.)
