The organization is a leading IT company in India, which specializes in deployment of cloud solutions for enterprise collaboration, network and cloud security, and disaster recovery.
It was using a Barracuda® Message Archiver (model 1050) - having 66 TB storage capacity - for archiving emails and facilitating email search, retrieval, and export queries.
The Barracuda® Message Archiver (model 1050) was a regular RAID array that comprised of 26 SATA HDDs (Western Digital and Hitachi), each with 3TB storage capacity. It had 34-TB of archived emails, which was critical data apart from the other data stored on it.
A potential problem in some of the HDDs deprecated the RAID array performance, which triggered disk replacement workflow to maintain the necessary redundancy levels. The storage administrator replaced the drives to rebuild the RAID array for reinstating peak performance. The RAID controller didn’t recognize the original configuration but instead showed the replaced drives as foreign configuration. As a result, the process failed and the message archiver couldn't detect the drives or mount the data. This problem persisted even after replacing the existing message archiver and using a new message archiver to read the drives. The Barracuda® archiver indicated a foreign configuration state for these drives.
The failure of Barracuda® Message Archiver (model 1050) turned the entire storage including the 34 TB archived email data files inaccessible. This may further lead to permanent data loss, in case the customer continued to forcefully reconstruct the RAID array again.
Failure of Barracuda® Message Archiver (model 1050) revoked organization-wide access to crucial information that was stored in these archived mailboxes. This was a major setback for the business, as the situation may impact the organization’s sales, business intelligence, and even strategic interests. The company was about to lose massive data assets — including 34 TB of critical archived mailbox data — that were gathered and honed over several years.
