We interrupt your regularly scheduled programming for the following public service announcement.
BACK UP YOUR DATA!
Go on, I'll wait a few minutes. Come on, just do it. You know you should.
Done? Good. You never know when those computer gremlins will decide to mess with you.
Here's my back-up routine, divided into daily, periodic, and archival routines.
At the end of every day, I copy the documents I've been working with (usually my WIP, an outline, and a "snips" file), onto a thumb drive. I also copy a set of those documents into a file on my desktop called, appropriately enough, "backups."
This gives me three copies of what I'm working on, one external to my computer.
Every so often, I will copy my documents to a second thumb drive. I'll also copy them to an external hard drive. This gives me some "extra" back-up, in case something goes seriously wrong.*
When I've got a decent draft of something (or if I'm feeling especially paranoid about losing work product), I'll email stuff to myself. That way, I've got a copy saved on my ISP's remote server, which I assume they back up periodically, too.
I'll also burn my "final" documents onto a CD or DVD and put it in my safe deposit box at the bank.
And of course, in the event of catastrophic failure, there are always at least five copies of various printed, hardcopy versions I use during the revision process.
As you can see, I think I take the proper precautions to back up my data.
SO ISN'T IT IRONIC THAT I LOST A DAY'S WORTH OF WRITING WHEN I BOTCHED THE DAILY BACK-UP?**
Now back to your regularly scheduled programming.
*I learned stuff like this when I worked at the Department of Redundancy Department.
**I love irony in my writing. In real life, not so much.
