Replication configuration

There are three types of replication configurations for your source server.

• File system replication—File system replication uses a Double-Take Availability file system mount point to capture data changes at the byte level. It is the most efficient type of replication. It provides a more detailed level of data selection, allowing you to include and exclude files and directories.
• Block device replication—Block device replication uses a loop device to capture data changes at the block level. Data selection is at the volume level. Generally, this replication configuration is ideal for non-file system type data, like raw databases.
• Full-server replication—Full-server replication captures the entire server for replication and protection using file system replication. When selecting this option, Double-Take Availability will automatically configure protection for all volumes. You can deselect any volume except root.

You cannot establish replication protection for the same set of data using more than one type of replication configuration. For example, /mydata cannot be protected by both file system replication and block device replication. However, you can protect two different file sets using two different replication configurations. For example /mydata1 and /mydata2 could be protected by file system replication and block device replication, respectively.
