ANECDOTE

Retail Edge Ransomware Example

  • A global retail customer operated over 500 edge locations, each running Kubernetes locally for store operations.
  • They faced a ransomware attack spreading through clusters, showing challenges unique to edge environments like resource limits and intermittent connectivity.
ADVICE

Use Specialized Backup Tools

  • Use backup platforms designed for Kubernetes and edge, like Veeam's Casten and CNCF's Canister framework.
  • Automate backup and restore with custom YAML blueprints that handle application specifics.
ADVICE

Backup Frequency and Incrementals

  • Prioritize backing up stateful applications frequently with incremental backups to save resources.
  • Incremental backups reduce storage needs and speed up backup windows, ideal for bandwidth-limited edge locations.
