Sometimes it feels like an impossible mission: keeping your organizations’ critical services protected-backed up, highly available, and quickly recoverable. This is especially true as business expectations keep rising, more systems are becoming critical, and overall complexity is threatening to derail your existing backup and DR plans. And of course, you already know that there is no “one size fits all” solution for protecting the enterprise: some services can tolerate less downtime and data loss than others, but you still need to match the protection level to the right architecture.
If this topic aligns with a key initiative at your organization, here is your invitation: Join the mission team. Your mission, should you choose to accept it, is to keep your organization’s critical infrastructure safe. Together, we will find the right mix of availability and cost, align recovery capabilities with recovery objectives, and sure, let’s save money and kill complexity while we’re at it.
To help organizations navigate through the architecture selection process, NetApp has put together a model that outlines which different technologies make sense for different investment and protection levels. It includes four basic architectures:
- Backup and recovery in the cloud: According to industry analysts, many enterprises are looking for a way to integrate cloud economics with the existing backup strategies. For many organizations, this is extremely cost effective, since it has data reduction and leverages cloud economics, yet continues to transport data offsite for site resiliency. And it can still provide quick recovery times if recent backups are retained locally. It also eliminates the need for a secondary site, or gives organizations the option of a low-cost tertiary site. Cost: very low. Recovery capabilities: slow/moderate, depending on how old the data is.
- Backup and recovery on-premises: This is the bread and butter of any continuity strategy. For relatively low cost, it offers point in time recovery either from a local site or secondary site. The next generation of backup and recovery on-premises incorporate snaps for rapid restore from any point in time and enhanced application integration for non-disruptive backups. Cost: Low. Recovery capabilities: moderate.
- Disaster recovery with asynchronous replication. These solutions are for critical data sets that demand fast recovery times at sites with geographic distance. The key to keeping recovery points and times short is WAN and storage-efficient transport mechanisms that send only changed data to that secondary site. And by the way, that secondary site could be the public cloud, a service provider, or another internal site. Cost: High. Recovery capabilities: fast
- Site-to-site HA with synchronous replication. For systems that cannot ever go down, in any situation, that require true 24x7x365 operations, site to site HA is the gold standard. Data is synchronously replicated between sites, with local HA within each site, providing always-on, always-available services. Cost: very high. Recovery capabilities: zero downtime, zero data loss
