I would also consider a relational database (such as mysql or postgres) for your data warehousing. These products (particularly postgres) are designed with data integrity first-and-foremost. Data formats can change over time, but the data can be easily extracted from the database to match the needs at hand. Data generated at different times can be easily mined and combined as needed. The data backup process is fairly straightforward. R already integrates with several relational database systems, so an integrated solution can be defined if one so desires. Look at RMySQL, Rdbi, and RdbiPgSQL for how to integrate R with MySQL and Postgres.
