Does a Time Machine drive need to be always on with a Mac?<article>
<section class="page">
<p>Time Machine is designed to back up your selected volumes every hour, writing any changes you’ve made into a new snapshot that captures only the differences between the previous backup. (Apple software, like Pages and Numbers, and a lot of third-party software create a version every time you save, providing backups within apps much more frequently than hourly.)</p><p>But some readers wonder what happens if they don’t keep their Time Machine drives powered up all the time. Apple designed Time Machine to be resilient, so it doesn’t skip a beat if one or more of the destination volumes you use for backups isn’t always available.</p><p>The ideal situation is that any drive you use is always plugged in and thus backups always happen while it’s on. This is particularly useful—maybe critical—if your Mac acts as a networked Time Machine destination for other computers on the network, as they may be backing up at times you’re not using your Mac—if a partner is working late or one of your kids is writing their term paper at 2 a.m.</p><p class="jumpTag"><a href="/article/3586115/does-a-time-machine-drive-need-to-be-always-on-with-a-mac.html#jump">To read this article in full, please click here[/url]</p></section></article>
