SyncToy will painlessly sync files and folders across PCs on a network or even sync between partitions on the same hard drive (attention dual booters!). You can sync music, photos, docs too and SyncToy will copy the new files to a USB or SD card. It can sync any file/folder including your Outlook .pst file to an external drive as well. It’s free, it’s easy and it works. All Windows OSs, x86-x64
I’ve been using this for a couple of years now and have recently been recommended Comodo Backup but I’ve not had time to play around with it too much; however, first impressions are good.
But since switching to windows 7, installing additional backup utilities don’t seem necessary now (though I still do) as the built in backup software has apparently improved significantly.
Maybe Geek could do a review on comodo and/or windows 7 backup?
