Optmization

Replication is difficult to maintain target consistency when the transmission bandwidth is low depending on the operating environment. In situations where the replication environment is not physically backed up, FSR provides the ability to optimize the transmission load by compressing the transmitted data and simultaneously perform real-time encryption as needed.

It also provides the ability to efficiently use the public network band by arbitrarily limiting the replication transmission band according to the operating situation. For more information, refer to Etc.

Split-brain detection

In case of unintended and unusual situations during replication operations, measures are required to protect data on the source side. Among them, if a primary becomes a secondary (spli-brain) at some point after disconnection, potentially causing data loss, it should be automatically detected and acted upon to block replication, a feature called split-brain detection. For more information about this, see Split-brain in Troubleshooting.

Statistics

It provides statistical information that monitors the operation of replication and provides real-time performance monitoring. For more information, refer to Checking Status

Snapshot

Snapshot

There may be times when failover fails due to a failure during replication operations, or when it is not possible to recover to the replication target due to security issues such as malware infection. In general, you should be prepared to recover in such cases by backing up your data. FSR supports recovery to a specific point in time through the snapshot feature and provides all the interfaces related to snapshot point-in-time recovery, including creating and managing snapshots and adjusting the space in the snapshot storage. For more information on this, see the snapshots section.

Terms

Node

A generic term for devices connected to a network, of which computer nodes are called hosts. Normally, node and host tend to be used without distinction. In this manual, node is used with the same meaning without distinguishing from host.
