About Access Appliance episodic replication
The Access Appliance episodic replication solution provides high performance, scalable data replication and is ideal for use as a content distribution solution, and for use to create hot standby copies of important data sets.
Access Appliance episodic replication lets you asynchronously replicate a file system from one node in a source cluster to another node in a destination cluster at regularly timed intervals. This allows for content sharing, replication, and distribution.
The Access Appliance episodic replication functionality allows episodic replication with a minimum timed interval update of 15 minutes and no set maximum. Unlike many replication solutions, Access Appliance episodic replication also allows the destination file system to be online for reads while replication is active.
Major features of Access Appliance episodic replication include:
Online access (read-only) to replicated data.
Immediate read/write access to destination-replicated data in the unlikely event that the source file system goes offline for a sustained period of time.
Load balancing across replication links.
Transport failover of episodic replication service from one node to another.
No limit on the number of episodic replication jobs that are configured, though the number of simultaneous/parallel jobs that can run at any time depends on the amount of memory available.
The Access Appliance episodic replication feature is designed to copy file systems only between Access Appliance clusters.
Note:
The Access Appliance episodic replication feature does not support user modifications to the target file system if episodic replication is configured.
