The Challenge:

A metropolitan US school district containing 165 schools was shut down by a Ryuk ransomware attack that affected its entire network. The attack was detected and interrupted, but a large portion of their systems had already been impacted. The client needed to recover important data from their storage system that contained 61TB of Commvault backups.

The Solution:

Ontrack utilized its proprietary Remote Data Recovery software and services to diagnose their environment and found that multiple volumes had been reinitialized and overwritten, requiring a difficult and time-intensive process that might not result in a full recovery.

Rather than working on the primary server environment, the client also had a secondary Commvault backup that resided on 268 LTO4 tapes that would take them a month to index in-house due to their Commvault server being reinitialized.

With Ontrack's 24-hour emergency service, our tape engineers were able to catalog and index the tapes within 3 days. After review, numerous tapes were selected for restoration which contained their most vital systems, and the school district was able to restore limited operations within a week.
