Is there a software product/module (open-source or commercial) that can provide incremental backups from Rackspace Cloud Files to Amazon Glacier?
We are looking for something that will provide the following functionality (or achieve the same result, i.e. a cost-effective backup plan for files stored in Rackspace Cloud Files):
- Work out which files have been added to or modified in a Rackspace Cloud account (since the last backup).
- Create a ZIP (or similar) of these files and store them in Amazon Glacier.
- Keep a record of which files are in which ZIPs.
- Ideally, restore either a single file or all files from Glacier back into Rackspace.
