Disk-based implementation of a data protection solution for multiple sites
This disk-based implementation of a data protection solution with Tivoli® Storage Manager uses inline data deduplication and replication at two sites.
This data protection solution provides the following benefits:
- Replication can be configured at both sites so that each server protects data for the other site
- Offsite data storage for each location is simplified
- Bandwidth is used efficiently because only deduplicated data is replicated between the sites
- Clients can automatically fail over to a target replication server if the source replication server is unavailable
In this solution, clients send data to the Tivoli Storage Manager source server, where the data is deduplicated and stored in a directory-container storage pool that is implemented in disk storage. The data is replicated to the storage pool on the target server for each site. This solution is suitable for environments that require disaster protection. If mutual replication is configured, clients at both sites can use failover recovery for continued backups and data recovery from the available server on the other site.
