Replicating File Systems

Replication Concepts

Source File System

The file system whose data you want to replicate to another infrastructure at regular intervals. Folder and file structure, snapshots, metadata, and permissions settings are replicated to the target file system. File system resource-specific data such as file locks, encryption keys, and tags are not replicated.

Target File System

The destination for replicated data from the source file system. Replicated data in the target file system has the same folder and file structure, snapshots, metadata, and permissions settings as the source file system. Only a file system that has never been exported can be used as a target file system.

Replication Resource

The control component of the replication process. It contains all of the necessary configuration information for the replication. The replication resource is attached to the source file system. The replication resource retrieves the delta of data between two snapshots of the source file system and sends that delta to the associated replication target resource. The replication target resource retrieves the delta and applies it to the target file system. Tags applied to a replication resource are copied to the replication target resource.

Replication Target Resource

The replication target resource is attached to the target file system and receives a replication snapshot from the replication resource and applies the data to the target file system. The replication target is automatically created when you create a replication resource, and any tags applied to the replication resource are copied to the target.

Replication Snapshot

The replication snapshot captures incremental changes in the source file system since the last snapshot. The snapshot data is transmitted from the replication resource to the replication target, which applies it to the target file system. The most recent two replication snapshots are retained.

Replication Interval

The frequency with which the replication operation is performed, in minutes.

Delta Cycle / Delta Status

A delta cycle is a complete replication operation.

Delta status values are the following:

• Idle: The replication is not capturing or applying data.

• Transferring: The replication is both capturing and committing snapshot data.

• Failed: The replication operation failed.
