Executive summary

Virtual environment backup uses hypervisor APIs for agentless, application-consistent backups without installing agents on each VM. Container backup requires different approaches than VM backup.

Overview

Agentless backup uses hypervisor APIs (VMware vSphere API for Data Protection, Microsoft VSS) to create application-consistent snapshots. Changed Block Tracking (CBT) enables efficient incremental backups.

Key Concepts

Agentless backup: Uses hypervisor APIs without installing agents. Application-consistent backup: Quiesces applications before snapshot. CBT: Tracks changed disk blocks for efficient incremental backup.

Best Practices

Use agentless backup for VMware and Hyper-V. Enable application-consistent backup for databases. Use CBT for efficient incremental backups. Test VM recovery regularly.

Key Considerations

Agentless backup requires sufficient storage for VM snapshots. Application-consistent backup requires VSS writers to be functioning. Container backup requires backing up persistent volumes separately.
