Configuring Exchange connection settings

This setting identifies the Target IP Address that the Double-Take Availability data will be transmitted through. You should only change this setting if you want to select a different route for Double-Take Availability traffic. On a machine with more than one NIC, this increases the flexibility of configuring Double-Take Availability activity. For example, you can separate regular network traffic and Double-Take Availability traffic on a machine. The default ports will be used.

In a cluster, the route should be set to the name of the Exchange virtual server (EVS) dependent IP address.

The Protected Storage Groups area displays the storage groups, mailbox, and public folder stores.

Select the Exchange storage groups that you want to protect. By selecting individual storage groups to protect, you can reduce the amount of data being replicated and filter out storage groups that do not need to be protected or failed over. Only the users associated with the selected storage groups will be failed over. By default, all storage groups are selected for an Exchange source.

The replication set that the Application Manager generates will include the directories and files needed to protect the selected storage groups. It is recommended that you protect all storage groups.

Note:

If you do not select all storage groups, you should make sure that other backups are available from which to recover the storage groups that are not failed over. Double-Take Software recommends that you place all query-based distribution groups in a single organization container and give the target server full control rights to the container and all child objects. Database files with a plus sign (+) in the name cause Application Manager to fail. You must rename the storage group and files to remove the plus sign.

You can also select non-application specific data under the Volumes folder.

Note:

If Override Generated Rules is selected on the Advanced tab, this control will be disabled.

To refresh the tree view to show new source directories or files that may have been added or removed, select the logical node, then click the Refresh button. If a node in the volumes branch is selected, then the items under that node will be refreshed.

The following options specify what files you want sent from the source to the target during a mirror.

• Full—Copies all of the directories and files in the replication set to the target machine. If a mirror has already been completed, another full mirror will overwrite the data on the target.
• Checksum—(Default) This option performs a checksum comparison calculation. A checksum calculation is a formula applied to blocks of data to determine if the binary make-up of the block is identical. If the checksums on the source and target machine are the same, the block is skipped. If the checksums on the source and target machine are not the same, the block on the source is sent to the target. With this option, the entire file is not overwritten; only the block that is received from the source is overwritten.

Note:

The Mirror type setting also applies to the restoration connection.

This setting enables compression of data that is transmitted from the source to the target. Significant improvements in bandwidth utilization have been seen in Wide Area Network (WAN) configurations or in any case where network bandwidth is a constraint.

Compression may be used in Local Area Network (LAN) configurations, though it may not provide any significant network improvements.

You can specify compression for different source/target connections, but all connections to the same target will have the same compression settings.

By default, compression is disabled. To enable it, select Enable Compression, then set the level from minimum to maximum compression.
