Welcome to FlyerTalk, Sage_Matt.

There have been a couple discussions about this topic previously, including these two that seem particularly relevant:

• http://www.flyertalk.com/forum/trave...=online+backup
• http://www.flyertalk.com/forum/trave...=online+backup

As mentioned in those threads, you need to be aware of restore issues just as much as backup.

I'm going to close this thread and ask that you continue one of those discussions instead as appropriate.

Thanks!
