Buy a new PC and it will ship with a large hard drive. The obvious choice is to split this in to multiple partitions so that you have a drive for your important media files. These can be audio tracks you’ve purchased online and are given a once-only right to download and store on your machine. It’s only right that you’d want to keep a regular backup of these files.
A wise choice would be Acronis True Image (now called "True Image by Acronis). This is backup and restore software that will enable you to select a drive or drive partition and then select an output for your backup. If it’s a small partition, you could easily backup online. Alternatively, a blank DVD or external hard drive. As Acronis True Image supports incremental backup, every time you run another backup of the same source, in the future, only updated or altered files will be backed up. With the new one-click backup, it means you can setup your source/destination and other settings, then click one button for the backup to start.
True Image offers far more than drive backup. Try&Decide enables you to create self-contained area on your drive so you can test new software without it affecting your PC. You can then install and test the new software and immediately remove, without having to uninstall. If you ever need to install a larger hard drive, use the Clone Disk function to move across the content from your existing drive.
Cleansing tools are included from the old Acronis DriveCleanser tool, which used to be a standalone application. These tools will shred files and documents so they can’t be retrieved and also enable you to safely erase the contents of your drive, in case you need to sell on your PC or ditch an old drive.
The latest True Image 2013 by Acronis ships with file synchronisation, so you can keep data in sync, between multiple computers (desktop and laptop) and another brand new user-interface, which is much improved over the previous revision.
Note that this is the iOS version.
