How the Restoration Process Works

1. The network administrator resolves the source machine problems and in the process reinstalls Storage Mirroring, if

necessary.

2. The network administrator initiates restoration through one of the Storage Mirroring clients.

3. Storage Mirroring determines which files to restore by using the replication set database backup from the target machine

or the original replication set database on the source machine. This option is defined by the network administrator.

4. Storage Mirroring determines which files from the replication set will be mirrored to the source machine by the

user-specified conditions set up by the network administrator.

5. Storage Mirroring mirrors the data from the target to the source.

6. The source machine returns an acknowledgement to the target when each mirror packet is received.

NOTE: If using the backup database on the target, you have the option of redirecting the restored data to a new

source machine or to a different location on the original source machine.
