Unsupported Third-Party Backup Corruption Risk

Using third-party backup solutions (Veeam, Cohesity, Rubrik) or Protection Domains to back up Pure Storage management VMs can result in corrupted instances with inconsistent data post-recovery, despite appearing functional.

Objects with failures in the last 3 consecutive backups indicate systemic problems beyond transient errors. These require immediate investigation to prevent complete data protection loss.

Uncontrolled storage capacity growth can lead to backup job failures and SLA violations. Monitoring capacity trends enables proactive resource planning before critical thresholds are reached.

Recovery operations limited to small batch sizes (5-15 VMs) dramatically extend RTO during mass restoration scenarios. This creates a recovery bottleneck during disaster recovery or ransomware recovery operations.

Fan or power supply unit failures in cluster nodes reduce redundancy and can cascade into broader system failures. Early detection of abnormal hardware metrics prevents unplanned downtime.

Disaster recovery health checks fail when backup SLA is not met due to replication lag between primary and DR clusters. This creates a gap between expected and actual recovery point objectives.

Network Connectivity Loss Between Cluster and vCenter

System errors in DR plans often stem from network connectivity issues between Cohesity cluster and vCenter. This prevents backup operations and DR plan activation despite correct configuration.

Backup windows configured with shorter cycles than achievable runtime cause persistent SLA violations. This creates false confidence in protection coverage while actual RPO objectives are missed.

Slow or unresponsive cluster services cause system errors in DR plans and backup failures. Service health directly impacts data protection reliability across all workloads.
