We are implementing database shadowing. How does it help us ensure we can recover from a data loss on our primary systems?

It sends transaction logs to a remote location, but not the files themselves. We can rebuild the transactions from the logs.
It makes an exact real time copy at another location, this can be another local disk or preferred remote to another type of media.
It takes a full backup of our database once a week to tape.
It uses a remote backups service that sends backup files electronically offsite at a certain interval or when the files change.
