When you backup your data (if you are not currently, you should be) you should always place the backup files on a drive other than the source. The reason is simple, if your source drive fails you need to restore the files from another drive.

While you can use an external hard drive or dump the files to a server (if you have one set up), the method I prefer is just storing them on a flash drive. Flash drives are rediculously cheap and have more than enough space to hold your backups. I use (tooting my own horn here) my home grown backup script to collect and compress the files I want to backup. Everything is automated via the task scheduler so it is a true ’set it and forget it’ method.

On a 2 GB flash drive, I am able to keep about 3 months worth of backups… so if I ever need to go back to a previous version I am all set.
