A Replication Pair is similar in concept to a Subclient which are used by other Agents; it maps a designated set of data on a source computer to a location on a destination computer, for the purpose of monitoring changes on the source and replicating the changes to the destination computer. A single Replication Pair can be configured to replicate all the data on a source computer, or multiple Replication Pairs can be created, allowing more granular control of data.
When creating a Replication Pair, and selecting the source and destination paths for replication, consider the following:
For instance, Replication Set 1 could have a Replication Pair configured as follows:
Replication Set 2 could have a Replication Pair configured as follows:
When selecting a destination folder for a Replication Pair, ensure that the selected path does not contain any data as the existing data will be pruned during Orphan File processing.
The activity of Replication Pairs can be controlled individually, or when acting from the Replication Set level, multiple Replication Pairs are controlled at the same time. Activities related to a Replication Pair include:
For more information about data types that can be replicated, see Supported Data Types.
For step-by-step instructions, see Add or Edit a Replication Pair.
Certain Replication Pair combinations are not possible, or are only possible using different Replication Sets. The following table highlights the most common such cases.
Type of Combination or Conflict | Windows | UNIX | Examples Note that (A), (B), (C) in the examples represent different computers |
