Time Machine Backup and Restore Experience

Sometime back, I read Scott Hanselman’s post on how meticulous he is about it backup strategy. That kind of meticulousness ensures you don’t ever lose any data whatsoever and you downtime in case of disaster is a minimum. Well, today I realized that Backups can help you with upgrades as well. So I am going to share how my backup strategy helped me upgrade my Hard disk without any Software Reinstall. A little bit of background first (or you can jump straight to the Upgrade).

Your System Environment

I do most of my development work on Windows 7 but I run all of them on VMWare VMs running on my MacBook Pro (OSX Snow Leopard). All the VMs are stored on another external 500Gb GoFlex drive. So easiest backup strategy for a VM is to simply copy the VMWare’s VM file periodically and you are done.

That strategy didn’t work very well when my Visual Studio got corrupted. I didn’t have anything to roll back to, so I had to create a new VM all together.

Take VM Snapshots

Moral from the corrupt Visual Studio story was to use the VM Snapshot functionality. That’s what I did when I created my new VM. Took a snapshot at significant steps of the installation process, like OS Install, Service Pack Install, Visual Studio Install, SQL Server Install etc.

Now I haven’t had a chance to test this backup strategy, yet, but I am hoping if my Visual Studio ever get’s corrupted, one of those snapshots will come to rescue.

Why not use Restore Points

I like to keep my VMs small about 60Gigs each, creating restore points would mean adding more diskspace to each VM. Also Restore point is too integral a part of Windows to help if some of the windows components got corrupted. Instead Windows Backup may be a better idea.

Use Source control, even for your personal code

I am a big believer in source control and I host most of my personal code on Bitbucket. So whether OSX or Windows 7 all my code is up in the cloud. You can refer to my  article on how to use Mercurial on Bitbucket. That way anytime OS has to be abandoned, only loss in source is the part that’s not backed up in cloud.

Time Machine on OSX

Now though my development work is on Windows 7 rest of the stuff is on OSX, so Office, Outlook, XCode etc. all run on the host system OSX. Obviously I have a significant investment in software here. I use Apple’s built in Time Machine software and a Seagate GoFlex 500GB USB2 external drive to do Daily backups. The Time Machine setup is pretty sparse and I use a third party app called Time Machine Editor to set it to a Daily scheduled backup instead of the default hourly backup that Time Machine sets out to do if enabled.

Selecting things to ‘exclude’ in Time Machine

Go to System Preferences –> Time Machine and select ‘Options…’ It will give you a list where you can add folders and drives that you don’t wish to be backed up. My external drives are excluded. So by default I backup everything else.

With this backup strategy in place I make sure Time Machine runs successfully every morning.

The Upgrade

I have been itching to upgrade my internal hard drive to 1TB so that I could host my VMs on the internal drive instead of having them run off an external drive. Was tempted to get an SSD but the high cost and failure rates so far have been a major deterrence. So instead of buying a 128GB SSD for ~$150 I bought myself a WD (WD10TPVT) 1TB for < $130 from good ol’ Amazon. This model is thicker than at 12.5 mm as opposed to the 9.5 mm for the stock drive. But it fits well in my late 2009 MacBook Pro. Your mileage may vary.

The hard drive replacement process is pretty much by the book (refer to the manual that came with your Mac), nothing there. I swapped out the 250 Gig stock Hard Drive with the new one.

Next was the restore part.

– I started the machine and inserted the OSX CD

– The installation process kicks off. Initially the OS won’t ‘see’ your new hard drive, because it’s not formatted. So use the Disk Utility to format and partition it. Then you can continue installing OSX (Snow Leopard in my case).

– The point at which it asks for user name give an account name that’s different from the one you used in your old installation. This comes in handy when running the Migration Wizard.

– Let OS install complete. Boot up and check for Software Updates. Let the Updates finish. Reboot if required.

– Now log on and go to Applications –> Utilities –> Migration Assistant.

– Select the Mac Hard Drive in the first page and go to next

– Select the Time Machine hard drive in the second page. Click next.

– Select all the backed up components including users and Click continue. It takes a little bit of time at this point. Once it is done it will ask what you want to do with the user that was backed up. In my case I had made the mistake of giving the same username and my old installation and as a result the second option ‘Replace’ was disabled. I had to back out, create another admin account, log in as that account, initiate restore then then ‘Replace’ that account from the backed up account. If you selected a different account name at the time of the fresh install, no worries, just continue. That’s it, sit back and let the restore complete. For 152GB odd of apps etc it took me about 2 hours to restore. But once it’s done almost everything is back to where it was.

What didn’t come through

It has been only a few hours since I completed by backup and I noticed the following:

1. I lost all my shortcuts on the Dock. They never got restored

2. Twitter app didn’t start on it’s own. And when it started it had lost all the accounts I was logged in for. I had to re-login every account again.

3. Office is asking for Product Key again. After I provided it, Outlook wants to ‘Rebuild’ the database index.

UPDATE 1 (March 24, 2012):

4. XCode recovery was also not complete. There is a very important tool that get’s installed with the XCode suite. It’s a command line util called ‘purge’. This util forces OSX to garbage collect Inactive memory. Without purge I can’t be as ‘agile’ I want to be with my VMs because either VMWare or OSX doesn’t release the memory of a recently shutdown VM. So either I run purge or reboot. Without which if I try to load a new VM it will crash completely!

What did come through

1. VMWare Fusion 4 works great. I am typing this on a VM that was created in the previous installation.

2. iTunes seems to have it’s clueless indexes of my music correct.

3. More importantly iPhoto seems to have ALL my images intact (a major part of the 150Gigs)


This was my first experience of ‘restoring from backup’. Looks okay so far. Knowing that my data is pretty much where I had left it, is rather comforting. There are some minor niggles as outlined above, but they are all pretty minor compared to setting up all the software all over again.

So backup my dear friends. It will help in more than one way!

One year with a MacBook Pro (Is the grass really greener…?)

It’s been a little over a year with my (then) prized purchase of a 13” MacBook Pro. You can read the initial impressions here

One year on, time to write down a follow-up on what I love, like and hate about the famed MBP.


  • Looks/Design:
    • Yes the famed industrial design at work. It’s looks are much envied and it’s one of a kind. Love the profile.
    • Glossy Display. The display is a love-hate thing. But I put it in the Love category because I don’t really like the Dell IPS’ hard coat anti-glare layer. So if anti-glare does that to IPS displays I am fine with a glossy finish.
    • Backlight keyboard: Though it’s not unique to the MacBook Pro, the fact that it comes by default is a big plus.
  • In OSX: OS X is every Mac fans’ crème-de-la-crème. The so called world’s most advanced operating system impressed only in a few ways
    • Boot up time and shut down times are super awesome.
    • Power Management is fantastic.
      • The advantage of control over hardware is evident as OSX works very hard to you give you optimal battery life. Though I couldn’t get anywhere near the touted battery life, I did consistently get 3-4 hours of normal use (browsing, pictures etc.)
      • Sleep mode is also very very stable. The only restarts required were when the upgrades required them (or to boot up into Windows 7)
    • The dual monitor support is awesome. Windows 7 still can’t do two monitors right.
    • Photo Library: It’s an awesome picture management software. No comparison with anything in Windows 7 out of box.
    • Performance: Though not mind bogglingly different, but I’ve run multiple XCode instances without too much trouble.


  • Looks/Design:
    • The sharp edges: Good aesthetics or not, the edges hurt. It’s disgraceful. They should be blunted a wee bit so that they don’t bite into your wrists when typing.
    • The (lack of keys in) Keyboard: It’s absolutely horrendous and irritating to not have Page Up/Down, Home/End and Print Screen/Delete buttons. The keyboard reminds me of the first 8086 computer we had. World has moved on, time to stop being a snob and put those keys in there Apple. Yes in a 13” laptop too.
    • Temperature control. It’s really pathetic that the system doesn’t respond to temperature changes till the temperature hits high 80’s (in C not F). Even then it seems reluctant to crank up the fan and allows system to run hot. I have to use smcFanControl to keep temperature in control when watching Flash or Silverlight movies.
    • Apple’s blaming Flash for all ills: It’s simply hypocritical of Apple to blame Flash of being power-hungry when you don’t expose the APIs for flash to use hardware resources through the browser. (This is changing now and both Windows and Mac versions of Flash are getting h/w acc support). Apple’s iTunes is no saint itself and syncing large number of photos with an iPad or iPhone takes the mickeys out of the system with temperature shooting up and battery life getting hosed.
  • In OSX
    • The Finder:
      • It seems archaic when compared to the Explorer in Windows. I find it irritating not to be a able to navigate to a folder by typing out the path directly.
      • No left navigation tree. The concept of one column for every folder you select is, okay, but I don’t like it.
    • Functionality
      • Photo Library: I haven’t figured out how to attach pictures that are imported into my Mac using Photo Library. So if I have to send a mail from Gmail’s webmail interface I can’t. I’ve to do it the other way, select images from Photo Library and then email them using Mail. The fact that a regular user has to ‘figure out’ how to do it is pretty ‘non-user friendly’.
      • Not being able to print your own Calendars using Photo Library feels a little ‘nickel-and-dimey’.

In Conclusion

I didn’t really use the MacBook Pro much till I had my regular software installed (Office for Mac). Even then it wasn’t much used because I just couldn’t devote enough time to iPhone development which was the primary reason for buying a Mac in the first place.

After I boot-camped it and installed Windows 7 I now use it more often. That only reflects the fact that I work on MS technologies and a Windows 7 OS serves me better.

OSX is a nice OS, but has some Apple specific idiosyncrasies, which if Apple were to drop would make it even more user friendly. Overall, the grass isn’t ‘much’ greener on the other side…

Updates [June 14, 2011]

1. I figured out how to navigate to an iPhoto folder to retrieve images directly. Right click on the photo in iPhoto and click ‘Show File’ to open it in Finder. Now you can attach it to any web-mail. Still the flow to get to my own pictures sucks.

2. As Navin commented below there are some shortcuts for the missing keyboard buttons, but I still miss my Alt+Prt Screen (Invaluable when blogging or writing articles), Home and End.

3. Temperature issues have improved vastly. I have the latest updates (Currently running 10.6.7), not sure at what point it improved but now the OS automatically cranks up the fan when I am running VMWare for my development. Still temperature hovers around 70+ without any intervention from smcFanControl, which I am okay with.

4. New irritation has cropped up, the damn thing emits shocks now. I googled it up and it’s supposed to be ‘common’ if you don’t use the three pronged plug. I am using it and I still get shocks. Unlike fanbois in the forums discussing the issue I refuse to say I enjoy them because I don’t. Haven’t narrowed down the exact scenario, but to add insult to the injury of sharp edges now I get shocks from those edges.

The ability to crank two VMs + itself all in 8 Gig memory (I upgraded the memory myself) is impressive. I am using the laptop all but like a server. So yes, annoyances aside, I am fine with the performance of the laptop.
