![]() ![]() It’s also worth making clear that the software itself has little in the way of cloud support. As we’ve mentioned, O&O DiskImage happily supports backups of specific folders and file types: it’s a little irritating (and baffling) that the exclusion filter isn’t available here, but you can optionally apply compression and encryption to keep your data compact and secure. ![]() It probably makes sense, therefore, to create a second, smaller backup set to protect your most important files. All of this means that a 2TB external drive should be able to accommodate a complete system archive dating back months or even years. ![]() If you need to save even more space, you can configure filters to exclude superfluous files and folders – once you’ve made that initial image, you can build incremental backups onto it, so subsequent updates will be far smaller. We tried backing up a Windows system disk containing 141GB of data, and were impressed to see O&O DiskImage Professional squeeze it into a 72GB image file. Inevitably, full-disk backups take up more space than selective ones, but they’re less weighty than you might imagine, as a lot of the files in a Windows installation are highly compressible. Plus, of course, if you’re hit by a malware attack or an OS failure, you can boot into the O&O recovery environment – the program includes a wizard that will write it to a bootable USB flash drive or ISO file – and roll your entire system back to an earlier state. ![]() Doing it this way ensures that nothing gets inadvertently missed out of your backup set, while finding and recovering files is a breeze, as your backed-up disk image can be mounted and browsed directly within the Windows Explorer. It’s an approach that encourages you to make regular backups of your entire system, and that’s not a bad idea. ![]()
