Mac Tips: Backup (Part 2)

Original image

Last week I covered backing up your Mac with Mozy -- a way to get your most important files backed up online for free. But because the free Mozy solution only stores up to 2 GB of data, you'll need to look elsewhere for a complete backup that covers your music, photos, and so on. You could pay a subscription for the Mozy full service, but this can get expensive over time -- and it can be very slow to upload tons of data over your home internet connection.

For Mac users, the obvious choice for full-drive backup is Time Machine, a new feature in Mac OS X Leopard. The ultimate "set it and forget it" backup, Time Machine uses an external drive (USB or Firewire) to back up your Mac's hard drive. It works in the background, waking up every hour or so to back up any newly changed files. It requires zero user intervention beyond attaching the backup drive. Setup is extremely simple: just plug in a new USB or Firewire drive to your Mac running Leopard, and you'll be asked whether you want to use that drive for Time Machine. Easy! Note: the initial backup will take some may want to make sure your Mac is set not to fall asleep during this backup, so you can be sure to have a complete backup the first time. Later backups only copy what has changed, and usually only take a few minutes. All of the backups happen in the background, so you can continue to use your Mac while the backup is in progress.

To retrieve files from Time Machine, you can enter the crazy 3D Time Machine view (pictured above), where you zoom back in time to find specific files. A timeline on the right shows backups over time, so you can easily zip to a specific date and see what was in a given folder. Personally, I've never used this feature -- it's rare that I actually lose a single file or want to go back to an old version like this. (Though Apple seems to think this is a really zippy demo, so you'll see it in lots of online reviews.) But what I do use is the whole-disk restore feature: you can boot from any Leopard install DVD, plug in a Time Machine backup drive, and use it to restore your Mac's main hard drive. This is extremely useful in case your main drive dies and is replaced with a new one, or you want to clone your drive onto a new Mac.

Apple just released Time Capsule, which is an Airport Extreme wireless router with a built-in Time Machine backup disk (either 500 GB or 1 Terabyte [!]). This further simplifies backup, since you don't even have to plug in a drive -- it's available wirelessly. Also, Time Capsule is handy if you have a lot of Macs in the house and want to back them up to a single, central place without carrying a disk around. So if you need a wireless router AND you want to do Time Machine, check out Time Capsule. But if you just want to get started with Time Machine, an external disk (USB/Firewire) will be cheaper. Generally you want your backup disk to have at least 1.5x-2x more capacity than you're using on your Mac's main drive. Thus, if you're using 60 GB on your laptop's drive, you'll want your Time Machine backup drive to be in the 90-120 GB range, at minimum.

One thing to keep in mind: if your Time Machine backup disk is in the same location as your Mac, you could lose both of them in a disaster. So if your house burns down (let's hope it doesn't), you'd likely lose both your Mac and the backup. If it's possible for you to store the backup disk in some other location (for example, at work, if you bring a laptop back and forth), you'll have a bit more security. This is also why you'll also want to use a solution like Mozy to back up your most critical files online, thus hopefully protected from any disaster that might befall your Mac. By using this two-prong backup strategy, you'll be protected against a wide variety of possible problems.

Thanks for reading about backup! Windows users, please chime in using the comments if you have suggestions for Windows backup solutions. Also if anyone has a request for a future Mac Tip, please leave a note!

Why the Best Time to Book Your Thanksgiving Travel Is Right Now
Original image

You're never going to get a true steal on holiday plane tickets, but if you want to avoid spending your whole salary flying to visit your relatives over Thanksgiving, the time is nigh to start picking seats. That's according to the experts at Condé Nast Traveler, who cite data from Expedia and Skyscanner.

The latter found that it was cheapest to secure Thanksgiving tickets 11 weeks before the holiday. That means that you should have bought your ticket around September 4, but it's not too late; you can still save if you book now. Expedia's data shows that the cheapest time to buy is 61 to 90 days before you leave, so you still have until September 23 to snag a seat on a major airline without paying an obscene premium. (Relatively speaking, of course.)

When major travel holidays aren't involved, data shows that the best time to book a plane ticket is on a Sunday, at least 21 days ahead of your travel. But given that millions of other Americans also want to fly on the exact same days during Thanksgiving and Christmas, the calculus of booking is a bit more high stakes. If you sleep on tickets this month, you could be missing out on hundreds of dollars in savings. In the recent study cited by Condé Nast Traveler, Expedia found that people booking during the 61- to 90-day window saved up to 10 percent off the average ticket price, while last-minute bookers who bought tickets six days or less from their travel day paid up to 20 percent more.

Once you secure those Turkey Day tickets, you've got a new project: Your Christmas flights. By Hopper's estimates, those flights rise in price by $1.50 every day between the end of October and December 15 (after which they get even more expensive). However, playing the waiting game can be beneficial, too. Expedia found that the cheapest time to book Christmas flights was just 14 to 20 days out.

Before you buy, we also recommend checking, which tracks 11,000 different airfares for flights around the holidays to analyze price trends. Because as miserable as holiday travel can be, you don't want to pay any more than you have to.

Try These 1957 Life Hacks Out Around the House

Life hacks existed long before websites like Lifehacker or Buzzfeed (or Mental Floss). In the mid-20th century, the magazine Science and Mechanics published an annual book called 1001 How-to Ideas, a book full of domestic life hacks. As Core77 reports, the YouTuber behind HouseHold Hacker discovered a vintage 1957 edition in his basement, and decided to see if the advice stood the test of time.

And most of the tips did. Here are a few of the best:

  • Have trouble peeling bacon out of the package without tearing it? Roll the package back and forth in your hands before you open it. That will break the adhesion holding the strips together, allowing you to peel them apart easily.
  • You can mount a flashlight on the floor by attaching it to an upside-down funnel with a rubber band.
  • You can move heavy furniture across your floors easily and safely by placing flattened egg cartons under each of the corners.
  • Attach a cheap metal coil to the top of a door hinge to keep a door open. No doorstop needed.
  • Doing a job around the house? Stick your loose nails or screws in a potato or a piece of hard fruit to keep them handy.
  • If your suction cup won’t stick to the wall, rub it with hand soap. The glycerin in the soap will help it hold.
  • Prevent hair from clogging your shower drain by sticking a piece of steel wool inside. When things get gross in there, just remove the steel wool and throw it away, replacing it with a new one.

Check out more of the tips in the video below.
