5 Ways to Solve Your Disaster Recovery Problem
No matter what problem you're trying to solve in life, you need a path to get there. Solving your disaster recovery (DR) problem is no different, and it pays to keep your problem-solving at a high-level before diving too deep into the weeds.
In this blog, we cover five potential disaster recovery solutions for your business and what steps you need to take to ensure your DR problems are solved.
Don't Skip The Crucial First Step
Before signing any agreements or buying anything, the stakeholders in your business should answer these five questions. After 15+ years of experience in this field, we recommend you ask yourself these questions as the critical first step in solving your DR problems. Getting through them will save you a lot of money and months or even years of frustration down the road:
- Is there a compliance issue you must solve, and does the CEO view this as a must-have?
- What applications and data must be recovered to support your employees and customers?
- How long can you do without these applications and data? How much data can you afford to lose?
- What is the financial risk of your business being without these applications and data?
- Who needs to be involved in this process within my company and do we have the expertise to evaluate the options?
The bigger your business, the more complexities will factor into these questions, but you'll thank yourself later for taking the time to answer them.
5 Disaster Recovery Solutions for Your Business
Once you've nailed down your answers from the first step, you'll be well-equipped to wade through the weeds of problem-solving. It's time to consider these five potential DR solutions through the lens of your business' unique needs:
1. Storage-based solutions are provided by the storage vendors and deployed as modules inside the storage array. This solution offers application consistency, but it functions at the storage layer and requires "like" hardware infrastructure in production and replication. This option is costly in implementation and management.
2. Agent-based solutions install agents onto the host server that is desired to be backed up. It allows for application-level recovery but requires installing an agent on each server. It also means more overhead, less scalability, and increased complexity to manage.
3. Snapshot/backup-based solutions enable a quick restore by “freezing” a live storage system or VM at a moment in time. Because snapshots are typically taken every four hours, four hours of data is lost after roll back. This solution causes high latency and requires large amounts of storage. It does not perform well under high loads or at large scales, which leads to high recovery point objectives (RPOs).
4. Native hypervisor replication solutions are hypervisor-aware but are managed on a per Virtual Machine (VM) or per Host basis. It does not have a central management interface, nor does it have consistency grouping. This makes it difficult to manage and maintain. Plus, it requires manual recovery operation.
5. Hypervisor-based replication solutions function so that each time the virtual machine writes to its virtual disks, the written command is automatically and continuously captured, cloned, and sent to the recovery site with no impact on application performance.
Hypervisor-based replication offers huge benefits without the drawbacks of other solutions and is optimized for virtual environments. It boasts application-level consistency grouping, easy scalability and granularity, recovery at the click of a button, continuous data protection, and more.
