Cisco ISE and Catalyst Center are critical for any network - having backups that are easy to restore when disaster strikes is key: Backup Assure is the answer. ![Backup Assure - A Disaster Recovery Case Study](https://blog.iptel.com.au/hs-fs/hubfs/Blogs/Backup%20Assure%20-%20A%20Disaster%20Recovery%20Case%20Study/Backup%20Assure%20-%20A%20Disaster%20Recovery%20Case%20Study.gif?width=737&height=395&name=Backup%20Assure%20-%20A%20Disaster%20Recovery%20Case%20Study.gif) Recommending a backup solution is more than just a technical decision, it's a choice that can define a customer's business continuity strategy for years. Last week, one of our customers faced the ultimate test of that choice. And the backup solution we recommended saved them $20,000-60,000 in downtime costs.

One of our customers experienced a recent catastrophic VMware infrastructure failure. Not a single VM corruption. Not a minor outage. Total platform failure. Multiple virtual machines corrupted and wouldn't boot. Recovery tools failed. The team scrambled to convert VMware virtual disks to Hyper-V format, attempting to salvage critical infrastructure on different platforms. Critical services down: - **Cisco ISE Cluster:** No Wi-Fi authentication. No secure network access. Employees locked out. - **Catalyst Center:**  No network visibility. No management capability. No automation. Production halted and every minute counted. The backup challenge: Their Backup Assure appliance was also running on VMware. When they tried to boot it on Hyper-V, it wouldn't start - wrong drivers, wrong platform. This is where most backup solutions become part of the problem instead of the solution - let's take a look at how we recovered this catastrophic event.

What happened next validated every reason we recommend this product: **Hour 1: Immediate Response** - Called Backup Assure support - Connected with senior engineer immediately (no ticket queue, no escalation delays) - Engineer understood the environment, the disaster, and the urgency - Fresh Hyper-V version of Backup Assure deployed within minutes Hour 2: Guided Migration - Backup Assure engineer walked our customer's team through converting backup - repositories from VMware to Hyper-V format - Step-by-step guidance on attaching converted data to new platform - Real-time troubleshooting as they worked Hour 3: Validation - Used Backup Assure's built-in validation tools - Confirmed every backup intact despite infrastructure disaster - No corruption. No data loss. - Knew with certainty they could restore before attempting it Hour 4: Full Restoration - ISE cluster restored from validated backups - Catalyst Center restored and functional - Wi-Fi authentication back online - Network management capability restored - Production resumed Total time from disaster to full recovery: 4 hours. Our customer's Hyper-V administrator said it multiple times during the support call: "We never would have worked this out without you."

But the real value goes beyond dollars: - No explaining to leadership why backups were corrupt - No panic searching for scattered backup files - No career-limiting "we can't recover" conversation - Confidence during crisis - Network disaster recovery assurance ASSOCIATED BLOGS: - [Backup Assure](https://blog.iptel.com.au/backup-assure-for-key-cisco-platforms) - [Cisco Catalyst Center Assurance](https://blog.iptel.com.au/blog/cisco-dna-center-assurance) - [5 Ways Catalyst Center Solves your Challenges](https://info.iptel.com.au/cisco-dna) --- ## Backup Assure: A Disaster Recovery Case Study: Summary In this blog, we have let you have the insight into a major failure. These can be truly heart stopping events for any network administrator and the difference between inconvenience and losing your job might well be the ability to return your network to service quickly! Any company running a network needs to have a strategy for how to support that network and keep it operational. Backing up and restoring key servers and devices is a major component - and on this you have to trust your vendor.
