How does the Reliance Family of file systems protect against data corruption?

Reliance Family file systems have a unique transactional architecture where two file system metaroots are maintained (unlike most other file systems which just have one). One metaroot points the known good state of the disk while the other points to the working state. Reliance Family file systems never overwrite live data; they always use free space for disk operations between transaction points. As a result, one state of the disk (known good state) is always reliable, no matter when power failure occurs. Because of this patented design, Reliance family file systems will not allow the typical data corruption caused by software issues on power loss. Note: Reliance Family file systems do not protect against hardware failures.
