Gmail doesn't have to go down globally for our email access to be cut off—our internet could go down, or our account could even be disabled. Whatever the case, it's a good idea to have a backup plan just in case the worst should happen.
They've got us covered with a number of methods for backing up our Gmail, starting with the really obvious solution of just using Thunderbird to back up our email with POP access, but we can backup our email with Fetchmail on Windows, Getmail on Linux, the standalone Gmail Backup tool, or even use Google Groups to backup your Gmail account.
So, don't think much.. just get urself backed up!!
