Behavior of the file systems on the episodic replication destination target
Destination file systems are mounted as read-write. Read-only access is allowed, but you are not expected to modify the destination file system content. While episodic replication occurs, destination file systems may not be in a consistent state. To provide consistent images of the destination file systems at different stages of the episodic replication, the episodic replication service creates and manages Storage Checkpoints of each destination file system.
The episodic replication service creates a new destination Storage Checkpoint:
Before the first session (before a full-sync)
After every successful episodic replication session (after every incremental sync)
Storage Checkpoints are automatically mounted under the .checkpoint
directory inside the target file system, for example:
/vx/target_mount/.checkpoint/ckpt_name
Where target_mount is the name of the target file system and ckpt_name is the name of the Storage Checkpoint.
You can use the Storage> snapshot list command to view these Storage Checkpoints and you can use Access Appliance commands to export any of these Storage Checkpoints for read-only purposes. The episodic replication Storage Checkpoint names are prefixed with vxfsrepl_ and also contain the Storage Checkpoint creation time.
