Replication configuration

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

File system replication—This option has been replaced by a new filter driver. You may be instructed to use this legacy driver by technical support. It uses a Double-Take Availability file system mount point to capture data changes at the byte level. 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.

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.
