f. The Restore To and Restore From paths will automatically be populated
when the replication set is selected. The restore to path is the directory that is
the common parent directory for all of the directories in the replication set. If
the replication set crosses volumes, then there will be a separate path for
each volume. The restore from path is the path on the target server where the
replicated files are located.
Note:
Restoring across a NAT router requires the ports to be the same as the
original connection. If the ports have been modified (manually or
reinstalled), you must set the port numbers to the same values as the last
valid source/target connection.
g. 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.
h. 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.
i. Select the restoration conditionals that you want to use.
● Overwrite existing files 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 is more recent—This option restores only those
files that are newer on the target than on the source. The entire file is
overwritten with this option.
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.
● Use block checksum comparison/delta block transfer—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.
j. 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.
