I'm a PhD student so back-ups are important. Office just crashed and corrupted a document I was working on. Luckily I was able to retrieve it from a temp file. This got me thinking about backup solutions. I do a nightly backup with Acronis but this won't help if a file I'm working on gets corrupted after working on it for a few hours. I want something that backs up all documents on my desktop but not other files I'm currently working on like videos and apps. Is this possible with current solutions or do I need to put them into a folder to be backed up? I could see this working better if I had multiple desk tops.
