![]() You can use Spotlight to preview an item to see if it's the one you want, and navigate back and forth through a folder's history. From there you can restore the file or delete it from the backup, if you wish. So, for example, if you have deleted or changed an item, you can go back to the last backup and locate it from the point before you changed it or, from the point before that, for as many backups as you have. ![]() #BACKUP SCHEDULER FOR TIME MACHINE MAC#By entering Time Machine's 'history' view, your Mac can display snapshots of every file and folder at every point it has been backed up. Time Machine would be merely a good solution if this was the whole story, but the reason it's special is that it lets you recover data in a really intuitive way. It also means you can rest assured that every new or modified file is being backed up, without you having to know what or where those files are. The great advantage of incremental backups is that they use far less space than just copying everything every time. It's able to determine this information thanks to some complex low-level technology using something called 'fsevents', though all most users need to know about this is that it works invisibly in the background. It works by initially making a byte-forbyte copy of your system to a secondary or external hard drive, including not just all your data and applications but also the system itself.Įvery subsequent backup that you perform or that is done automatically is incremental, meaning Time Machine only backs up files that have been added or modified since the last backup. You'll find Time Machine in your Mac's System Preferences if you're running OS X 10.5 or 10.6, with a large, friendly on/off button to activate or deactivate it. There are no complicated options, no fiddling and best of all, it works automatically. It was a typically Apple-like approach to nudging users towards a certain way of working – in this case, backing up. ![]() With OS X 10.5, Apple introduced Time Machine, an outwardly simple and straightforward backup tool tightly integrated into the system. ![]()
