Have you backed up your files lately? Articles, book manuscripts, pictures, anything that can’t easily be replaced should be backed up somewhere to safeguard your precious resources. Save regularly and often.
A great way to do save your important files is to use DropBox. I use it regularly because I don’t want to wake up one morning and find that my hard drive is inaccessible, and that I’ve lost days and even weeks and months of precious work.
It’s easy to use and you can get 2GB for free here: https://db.tt/Z2l2DOw8
