I want to sugest power saving changes after installing and handling creation of Time Capsule for Time Machine for my home network ( form my previous article ). I like when it's quiet. And like when disks does not spin, when it's not necessary to do so. So if you usually backup once in some hours and main time (Night and a part of the day) you do not touch a Time Machine... You would probably want to slow down your disks for that time. Fortunately Linux does it very well. And support of it is encoded into Linux core (kernel). You just would need a UI for this possibilities and a bit of knowledge and luck ;) Warning: Operations described farther may be potentially hazardous to your hardware. So now after you are warned ;) let's continue. I guess I will not touch those hazardous functions, but you may, typing wrong letters to this command in Linux shell... So be careful. Better read manuals for farther commands and so on... Anyway what we need is a UI. And...

The real article name might be something like:  Configuring Raspbery Pi to serve like a Time Capsule with Netatalk 3.0 for Mountain Lion.  But it's too long ;) Here I will describe the process of using Raspberry Pi like a Time Machine in my network. To be able to backup your MAC's remotely (Like it would be NAS of some kind). It assumes you have a Raspberry Pi and have installed a Raspbian there and have a ssh connection, or somehow having access to it's console. Refer to my previous article for details . Now that we have a Pi that is ready for action let's animate it. So to make it suit you as a Time Capsule (NAS) for your MAC's you need to do those basic steps: - connect and configure USB hard drive(s) - install support of HFS+ filesystem to be able to use MAC's native filesystem - make mount (auto-mount on boot) of your hard drive - install Avahi and Netatalk demons - configure Netatalk daemon to make it all serve as a Time Machine - configure ...

Here are my first steps. And I hope you will find something useful here, while configuring your Pi... First of all. Mine have been bought on ebay, from resellers. And were delivered a while ago. Main purpose of this purchase war to attach a headless server to my router. I have 2 external HDD's and would like to have torrents, Time Mashine fro my macs and so on. So buying a handheld computer like this would be a bargain for me. As for built in decisions like some kinds of NAT devices and different routers with external HDD features... They are either cost a lot or lack some kinds of desired functionality. So the goal is to make some kind http/api manageable server in my local network with Time Mashine and file storage/backup. Just for fun. And to have only laptop on my work table. SO back to the Pi. If you are buying "device only" configuration, like I did. First of all you'll need some different kind of things many computer fans usual...

Today I'll try to cover my migration experience. I have bought myself an OCZ Technology 128GB Vertex 4 SSD from Amazon. And I also have an external 1 Tb HDD. I'm using it for migration purposes as a backup Time Mashine. So to migrate yourself without reinstalling operating system and so on you need: 1. Compact your data. Usually HDD's, installed in Mac's, are much bigger then SSD's you buying. And to tell you the truth, you probably do not need a 512 Gigabytes SSD at all. Most of data are accessed rarely and do not require speedy storage. So COMPACT them. Move to an external HDD and/or delete. Time to cleanup one word. There are also several places that can be easily deleted without much troubles. They are iTunes backup caches for your iOS devices, like iPhones and iPads. they are usually sotred on your user library path. You can delete them without sorry from either: ~/Library/Application Support/MobileSync/Backup  folder or in your iTunes => Preferen...
