There are some tools I use every day. Dropbox, an online file management service, is one of these. (Fun fact: you can even use it as an ad hoc web server, or even publish attractive and simple websites from it. ) I use it to store vital personal and work files, it synchs those files between my computers and I can also grab them from a secure website. Deleted files can be recovered and you can revert to an earlier version of a file. You can share your files with other Dropbox users. In short, I wouldn't start a new project without it.
The basic account is free of charge and allows 2Gb of space. If you use this referral link, you and I both get an extra 250Mb. Thanks for your consideration.
