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.

The Advanced tab includes advanced configuration options.
Replication set rules
A replication set defines what directories/files are to be protected by Storage Mirroring. By default,
Application Manager selects all of the necessary directories/files to protect SharePoint based on your
source server configuration. These include the SharePoint application data and transaction logs,
tempdb files, and SharePoint error logs. By default, the Application Manager-generated replication
set will be named
SharePointdag01_<source server name>_<target server name>
.
You should only modify the replication set rules if there are additional directories/files specific to your
configuration that must also be protected with SharePoint. Modifying the default configuration for
replication set rules may affect whether data can be successfully replicated. Do not modify the
replication set unless you are very familiar with Storage Mirroring and SharePoint.
To change the replication set rules:
1. Select the Override Generated Rules checkbox.
2. To add a replication set rule, click Add. The Add Repset Rule dialog box will appear.
NOTE: When this box is selected, the Protected Databases control on the Connection tab will
be disabled. For more information, see Protected Databases on page 7-14.
