VSS Writer Diagnostic & Repair Guide
For VSS writer failures behind Commvault, Veeam or Windows Server Backup errors. Paste raw vssadmin output to see which writers failed, with read-only checks first and clearly labelled repair steps for each writer’s service.
Cloud Restore Time & Cost Calculator
How long a large restore from S3, Glacier, Azure Archive, Wasabi, B2 or an on-premises appliance takes, what it costs in retrieval, request and egress fees, and whether it meets your RTO.
Backup Readiness Score
20 questions, about 6 minutes. Get an A to F grade for how recoverable your backups are against the 3-2-1-1-0 rule, with a prioritised fix list.
Support Bundle & Log Sanitizer
Replace secrets, emails, usernames, IP addresses, hostnames, WWNs and IQNs with consistent placeholders before you share logs with vendors or AI tools. Review the output before sharing.
Linux df vs. du Discrepancy Decoder
Find where disk space went when df -h is 100% full but du -sh cannot find the files: deleted-but-open files, data hidden under mount points, reserved blocks or inodes.
VMware Snapshot Consolidation Planner
Estimate snapshot merge time, check datastore free space, flag snapshots outside VMware best practice, and get a read-only-first PowerCLI runbook before deleting production snapshots.

PROFESSIONAL SERVICES
Technical Consulting & Incident RCA
Direct senior engineering engagement for critical outages, complex backup remediation, and infrastructure reliability.
Complex Incident RCA
In-depth forensic log correlation and root-cause determination for persistent, recurring, or multi-vendor infrastructure failures.
- ✓ Multi-source log correlation
- ✓ Verifiable finding (not guesses)
- ✓ Executive & technical report
Backup Architecture Audit
Comprehensive assessment of Commvault, Veeam, or Cohesity environments against ransomware immutability and real recovery RTO/RPO SLAs.
- ✓ 3-2-1-1-0 compliance verification
- ✓ Deduplication & capacity analysis
- ✓ Air-gap & immutability review
Runbooks & Automation
Convert chaotic manual firefighting into predictable, automated operations with documented runbooks and idempotent Ansible/PowerShell scripts.
- ✓ Repeatable verification steps
- ✓ Safe rollback procedures
- ✓ Automated pre/post health checks
Evidence-Based Incident Investigation Engine
A new platform for infrastructure incident investigation: from vendor support bundles to unified timelines and verifiable root cause analysis.
