I know you’re backing up your hard drive and network data, right? You use Dropbox, Carbonite, MOZY, AmazonS3, or JustCloud. Or maybe you’re a Mac Time Machine junky. Either way, here’s hoping beyond hope you’re doing this regularly.

Of course, now that so many of us are moving stuff to the cloud, we’ve got an increasingly perplexing new issue.

How do we back up all that stuff that sits on someone else’s sever?

Do you remember a while back when a whole bunch of Gmail users woke up and found their email files wiped out? We can argue whether or not that’s a good thing, but I’m guessing there were some really important emails that went missing.

Okay, how about this one – you fire up your WordPress blog and discover that your low cost host has decided to go out of business and take your SQL database (otherwise know as you blog posts) with them. (I suppose this could happen to your really expensive web host too, but you get the idea.)

And one last illustration to strike a little more fear. You fire up Basecamp in hopes of finding that critical contract your client signed and uploaded only to find a blank project folder. (Basecamp is an awesome product and I’m sure this would never happen, but what if it did?)

See, we’ve come to depend on all these tools, services and stuff that we routinely and perhaps a bit naively imagine will always work, sync and be safe.

I believe we all need to start looking into some redundancy in our backing up. You could make a case for having an external drive and Dropbox or Dropbox and Mozy for your regular backups, but the real gap may be in backing up all those services.

Here are couple services that are designed to help you do just that.

Backupify – allows you to create regular backups of all your social media updates, email, calendars, Google docs, and photo sharing sites. They even have a plan that’s made for Google Apps for Domains users.

CloudHQ – If you’re already a Basecamp, Dropbox and Google Docs user you’re going to this CloudHQ was built just for you. This service syncs and backs up all your Basecamp data, backs up most of your cloud data to Dropbox and really enhances collaboration using Google docs with Basecamp syncing.

BackupBuddy – It’s just a really good practice to routinely backup your WordPress blog. BackupBuddy is a plugin that can be set to make automatic backups to S3 or even Dropbox. I use Rackspace for hosting and they have a cloud backup tool as well.

I know this just one more thing to worry about, but once you set it up and automate it, it’s actually one less thing to worry about!
