Configuring source data processing options

1. Right-click a server on the left pane of the Replication Console.
2. Select Properties

3. Select the Source tab.

   

4. Specify how the source will process data.
• Replication Packets to 1 Mirror Packet—You can specify the ratio of replication packets to mirror packets that are placed in the source queue. Specify a larger number if you have a busy network that has heavy replication. Also, if you anticipate increased network activity during a mirror, increase this number so that the replication queue does not get too large.
• Replicate NT Security by Name—This is a Windows option only.

• Ignore Delete Operations—This option allows you to keep files on the target machine after they are deleted on the source. When a file is deleted on the source, that delete operation is not sent to the target. (All edits to files on the source are still replicated to the target; only deletions of whole files are ignored.) This option may be useful to give you an opportunity to make a backup of these files in the event they are needed in the future.

  If delete operations are ignored long enough, the potential exists for the target to run out of space. In that case, you can manually delete files from the target to free space.

   

• Maximum Pending Mirror Operations—This option is the maximum number of mirror operations that are queued on the source. The default setting is 1000. If, during mirroring, the mirror queued statistic regularly shows low numbers, for example, less than 50, this value can be increased to allow Double-Take Availability to queue more data for transfer.
• Size of Mirror Packets—This option determines the size of the mirror packets that Double-Take Availability transmits. The default setting is 32768 bytes.

• Use Checksum on All blocks of data during a Difference Mirror—This option allows a file difference mirror to check each block of data, regardless of the file attributes. If this option is not marked, Double-Take Availability will assume files are synchronized if their attributes match.

  Database applications may update files without changing the date, time, or file size. Therefore, if you are using database applications, you should use the Block Checksum All option to ensure proper file comparisons.

   

5. Click OK to save the settings.
