We are implementing database shadowing, how does it help us ensure we can recover from a data loss on our primary systems?
A: It sends transaction logs to a remote location, but not the files themselves. We can rebuild the transactions from the logs.
B: It uses a remote backups service that sends backup files electronically offsite at a certain interval or when the files change.
C: It makes an exact real time copy at another location, this can be another local disk or preferred remote to another type of media.
D: It takes a full backup of our database once a week to tape.
