About backing up your documents safely.
As far as Atlantis is concerned, you could choose a removable media (e.g. a thumb drive) as the Atlantis “Backup Folder”. In this way, you’d probably run less risk to lose documents after a system crash.
You could also use an online backup service that would keep your Atlantis document folders in sync with your “cloud” storage space. For example, SugarSync (http://www.sugarsync.com/) gives you 5GB of free online backup storage. Here is from the site (https://www.sugarsync.com/products/backup.html):
HTH.Continuous automatic file backup
SugarSync's online backup service works quietly in the background without interfering with your productivity. Rest easy with the confidence that any files you change or add to the folders you have selected for syncing will be synced and backed up automatically to your secure Personal Cloud. You just "set it and forget it."
Restore all your data
Your computers may come and go, but your photos, videos, and movies cannot be replaced. SugarSync keeps all your personal data safe from computer crashes. It's simple to restore your files and folders to a new computer.
File version control and recovery
Easily view and restore previous versions of your files. SugarSync keeps the previous five versions of all your document in case you need to reference or recover them in the future. Only the most recent version of each of your files counts towards your storage limit.
Web file archive
SugarSync's Web Archive is a simple way to take advantage of cloud storage. The Web Archive is a location for backing up and storing files online with no syncing or updates. Everything you store in SugarSync's Web Archive is accessible from the web and your mobile devices.
