DocSyncer

Storage and backup applications are among the most critical in any major corporation. Because missing or corrupted backups tend to show up only when someone needs to use them to recover from some data disaster, there's not much room for error. Lost data equals lost revenue and possibly legal liability, if the lost data are relevant to the financial performance of the company.

DocSyncer

DocSyncer also focuses on file-level backup, but is designed to work with Web-based storage services to back up your critical documents someplace you're much less likely to spill coffee or magnets on them.

DocSyncer specifically works with Google Docs to store as many documents as will fit in your Google Docs account – usually 10 GB. It offers version control and remote viewing and backup of documents from any of your machines via Google Docs' Mobile access.
