Lost database replica recovery

Occasionally, a replica is lost. This loss is usually due to a hardware failure (for example, disk crash), a software failure (for example, OS-level file system corruption), or a human error. If an unreplicated database is lost, you can restore a recent copy from backup and resume development work. The changes made between the time of the backup and the time of the failure are not recoverable.
Similarly, if you lose a replica, you can restore a recent copy from backup; however, this can result in the following conditions:

Because this procedure involves substantial effort, it is intended for situations where serious damage has occurred. (For example, the disk containing a replica is unusable.)
