7. Select the Use Backup Replication Set check box to use the target’s copy of the replication set
database for the restoration. If this check box is not marked, you will be accessing the
replication set information from the source.
8. Select the Restore Replication Set check box to restore the target’s copy of the replication set
database to the source during the restoration process.
9. Select the restoration conditionals that you want to use.

Overwrite existing data during restore — This option restores all existing files by
overwriting them. Any files that do not exist on the source are written also. If this option is
disabled, only files that do not exist on the source will be restored.

Only if backup copy’s date is more—This option restores only those files that are newer on
the target than on the source. The entire file is overwritten with this option.

Use Checksum comparison to send minimal blocks of data—Specify if you want the
restoration process to use a block checksum comparison to determine which blocks are
different. If this option is enabled, only those blocks (not the entire files) that are different will
be restored to the source.
10. If you want to configure orphan files, click the Orphans tab. The same orphan options are
available for a restoration connection as a standard connection. See Configuring and
removing orphan files on page 10-5 for more details.
11. Click Restore to begin the restoration.
NOTE: If you are using a database application, do not use the newer option unless you
know for certain you need it. With database applications, it is critical that all files,
not just some of them that might be newer, get mirrored.
