Drive additional value
Once you've introduced some type of 1DR component and, possibly, a 2DR component, the next step is to drive additional value from your data protection environment by layering in technologies such as CDP, data deduplication, snapshot, compression, etc. The idea is to leverage these technologies to achieve specific recovery, capacity or security objectives. For example, if your objective is to improve RTO and RPO, you could introduce some type of CDP or snapshot capability. If you want to reduce capacity requirements, you could try data deduplication (you should also consider data deduplication during the evaluation process of 1DR technologies), compression and so forth. If your objective is to add a disaster recovery component, you should consider remote mirroring or replication.

Data deduplication, with its ability to reduce the backup capacity footprint by up to 25 times or more, can have a significant impact on both 1DR and 2DR processes. These include:

  • Lower backup-related costs. Simply put, more organizations are likely to implement disk-based products if they're more affordable. In fact, ESG's research shows that the cost of a disk-based solution is the No. 1 reason organizations don't implement these types of products. In the case of 1DR, data deduplication can lower total disk costs significantly; in some cases, to less than that of a similarly sized tape library.
  • Longer retention periods.

  • Organizations can keep data on 1DR technologies longer. Data deduplication frees up lots of disk space, which can be used to protect other data types that are still backed up to tape or to enable longer retention periods for 1DR data.
  • Reduced WAN traffic. Less data to back up means less data to be moved over the WAN during the 2DR process. For some organizations, data deduplication may be the difference between replicating (or not replicating) data for disaster recovery purposes. For those firms already replicating data, it means a significant reduction in WAN traffic and WAN-related costs.
Tape's RTO/RPO can't keep up
Thirty-one percent of organizations say they'll experience significant revenue loss or another adverse business impact within one hour or less of application downtime. When you factor in traditional tape-based backup and recovery processes with RPOs averaging 12 hours or longer, and RTOs ranging from four to 24 hours, it's no wonder organizations are rethinking their data protection strategies.

If you've permanently replaced your tape-based infrastructures with some type of 1DR technology, kudos. If you haven't, now is the time. Start big or start small, it doesn't matter. Just do something. Thinking in terms of 3DR will help you get your feet wet.
