StoreVault Replication
Easy to Manage Offsite Data Protection
StoreVault Replication enables administrators to replicate data from a StoreVault to one or more “destination” StoreVault units. File-based or block-based data can be easily replicated over a WAN to a remote location to protect data in the event of a disaster or to distribute data to remote offices.
StoreVault Replication provides simple, easy-to-manage off-site data protection. It is based on Network Appliance™ SnapMirror® technology and replicates data to one or more StoreVault or NetApp FAS appliances in multiple fashions, including one to one, one to many, many to one, and round robin. Replication is a useful tool for off-site backup, data distribution, or simple round-robin geographic disaster insulation. Source data can be automatically updated to remote StoreVault units while the locally created originals remain in service. Replicated data is periodically updated to remain current and available for applications such as disaster recovery, offloading tape backup, read-only data distribution, testing on nonproduction storage systems, online data migration, and more.
StoreVault Replication software has many bandwidth-saving features that lower the infrastructure cost of data replication and throttling, and disaster recovery. After replication is initialized, only new and changed blocks need to be updated over the network. By replicating only changes, StoreVault Replication significantly reduces network bandwidth requirements. In addition, StoreVault Replication takes checkpoints during data transfers. If a transfer is interrupted, it will restart from the most recent checkpoint. StoreVault Replication also performs intelligent resynchronization, eliminating the need for full transfers when recovering from a broken replica or loss of synchronization.
StoreVault to FAS Replication
StoreVault to FAS Replication enables administrators to replicate data from a StoreVault system to a NetApp FAS system. Both file and block data can be easily replicated over a WAN to a remote location to protect data in the event of disaster or provide a consolidated data repository. StoreVault to FAS Replication is similar to StoreVault to StoreVault replication and is based on Network ApplianceTM SnapMirror® technology. It is a separate license from StoreVault and has specific requirements on the FAS system. See below for details.
| StoreVault Replication Key Features | |
Feature |
Benefit |
Enterprise-Proven Replication Technology |
Uses Network Appliance SnapMirror technology for fast, reliable data replication. |
Ease of Configuration |
Simple scheduler interface allows you to set up replication in minutes. |
Optimized for WAN Environments |
Only changed data is transmitted. Checkpoints and intelligent resynchronization eliminate need for full transfer after update is interrupted. |
Remote Access to Replicated Data |
Accesses read-only copies of replicated data at remote locations for off-site backup or data distribution. |
| Scheduled Asynchronous Updates | Replicas are updated as often as every four hours based on the selected schedule. |
| Flexible Configurations | StoreVault Replication can be added as an option to an existing StoreVault to make it either a source or destination for replication. Supports one-to-one, one-to-many, many-to-one, and round-robin configurations. |
| StoreVault Replication Technical Specifications | |
Hardware Requirements |
Replication licenses must be purchased for both the source and destination StoreVault systems. NOTE: This product does not support replication to NetApp FAS series products. |
Software Requirements |
StoreVault Manager 2.0 or higher, Data ONTAP® SVE 1.1 or higher (StoreVault to FAS replication requires StoreVault Manager 3.0) |
Maximum Number of Destination LUN Replicas |
64 (for StoreVault destination systems); Max number for FAS systems is higher and depends on specific system |
Maximum Number of Destination Shares Replicas |
64 (for StoreVault destination systems); Max number for FAS systems is higher and depends on specific system |
| Maximum Number of Exports Replicas | 64 (for StoreVault destination systems); Max number for FAS systems is higher and depends on specific system |
| Update Frequency (Minimum) | 1 Hour; minimum update period depends on rate of data change |
| Maximum Concurrent Active Sessions |

| Supported Replication Topologies | • One to one. One source is copied to one destination (Figure 1 below). • One to many. One source is copied to many destinations (Figure 2 below). • Many to one. Many sources are copied to one destination (Figure 3 below). • Round-robin or cascaded. One source is copied to one destination, but incorporates multiple StoreVaults. This ensures that a copy always exists in another location. (Figure 4 below). |
