l
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.
l
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.
l
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.
k. If you want to configure orphan files, click the Orphans tab. The
for a restoration connection as a standard
connection.
l. If your original source was using Replicate NT Security by Name, you must
enable that option on the target before you start the restoration. The option is
available on the target’s Server Properties on the Source tab.
m. Click Restore to begin the restoration. You can identify a restoration
connection because it is enclosed in parenthesis ( ) and it has _Restore
appended to the end of the replication set name. The initial restoration is
complete when the Mirror Status is Idle. After the Mirror Status is Idle, the
connection will continue replicating any on-going data changes from the
target to the source.
Note: During the restoration, only the data is restored back to the source.
Shares are not created on the source during the restoration. Shares
that were created on the target during failover will need to be created
manually on the source.
