Snapshots are one method of data protection, but it’s not a substitute for backups, said Krista Macomber, a senior analyst at Evaluator Group. It’s important not to conflate the two because backups, which can be isolated from the production environment, provide a better means to recover from ransomware.
“Backups are the insurance policy that can allow a customer to recover if they’re attacked by ransomware,” Macomber said.
The container backup market is still too nascent to pinpoint how customers generally prefer to protect their Kubernetes environments, Macomber said. However, Kubernetes workloads require persistent storage, which is becoming just as important to back up as any on-premises or virtualized workload. This means customers will likely want to follow the same practices that worked in the past and apply them to Kubernetes protection, such as adhering to the 3-2-1 rule, Macomber said.
