When Time Machine was released with Mac OS X 10.5 (Leopard) back in October 2007, it was one of the highlights of the new release. Apple was the first company to offer a fully-functioning, built in backup utility into their operating system and in true Mac-style, they pumped it full of eye candy. Well, only Apple could take a simple system utility and transform it into a work of art.
Although Time Machine is good for recovering files if anything does happen to your Mac, it is a bit basic in its functionality. You do not have the option to schedule backups depending on when you want them – when your external hard disk drive is plugged in (or the device you are backing up to), Time Machine will simply sync any changed files and folders hourly.
For the average user, this won’t cause too much of a problem, but for someone who uses their Mac for high-end software or gaming, the backup can slow down the performance of your Mac. Time Machine also isn’t a true backup option per se, as it does not create disk images (unlike other programs), where you can restore your Mac in the case of a drastic failure.
This is where ChronoSync comes in. At $40, it is quite a pricey alternative to Time Machine (which is bundled in with Mac OS X 10.5 and above) and some might question paying this amount for a piece of software which is pretty much identical to something they get for free anyway. I decided though to download the 30-day trial version of ChronoSync to give it a test run and to see whether it is really a viable (or better) alternative to Time Machine.
Disk Utility is an excellent OS X utility for managing hard drives and removable storage. If you’ve ever installed OS X, wiped a hard drive clean, or needed to re-format a USB stick, there’s a good chance that you’ll be familiar with the app. Whilst managing disk images is undoubtedly Disk Utility’s forté, it can also be used to good effect for creating images.
This how-to will walk you through how simple this process is. We’ll illustrate how to create a simple disk image for storing files, a few of the uses that images can have, and also investigate how images can be encrypted to keep your files secure.
