Emailing yourself important documents that change often is a quick and dirty – yet very effective – form of backup, especially if you’re using a web-based email solution like Gmail or Yahoo! Mail. By regularly emailing herself a copy of the Word document she’d been slaving over for months, my sis would be storing it somewhere off-site (in case of drive failure, theft, fire or flood) and she’d also build up a directory of document versions over time, all in her inbox. Even with my fancy-pants automated backup system, every once in awhile I get to emailing myself documents that I’m changing rapidly throughout the course of a day. You know, just in case.
