Appliance-based implementation of a data protection solution for multiple sites
This implementation of a multi-site IBM Spectrum® Protect data protection solution uses appliance-based data deduplication and replication. A standby server is configured at a second site to recover data if the primary server is unavailable.
This data protection solution provides the following benefits:
- Performance is optimized for backups on high-speed storage area networks (SAN) and for use with IBM Spectrum Protect for SAN, when clients back up directly to SAN-attached virtual tape devices.
- Fast, appliance-based replication frees the server from having to track replication metadata in the server database.
- Bandwidth and storage space are used efficiently because only deduplicated data is replicated between the sites.
- A standby environment provides for disaster recovery, but does not require the amount of resources that are needed for a fully active site.
In this data protection configuration, the server uses hardware appliances to deduplicate and replicate data. The appliance at Site A deduplicates data and then replicates the data to the appliance at Site B for disaster protection. If a failure at Site A occurs, you make the standby server active by restoring the most recent database backup, and by activating the replicated copy of data.
