Introduction:
The client is a confidential, mid-to-large audit and compliance organization that provides statutory audits, forensic audits, and regulatory assurance services to enterprises across multiple industries.
To comply with long-term retention and regulatory requirements, the organization stores historical audit working papers, financial records, and compliance evidence on LTO tape backups using Tivoli Storage Manager (BA Client) in a secure on-premises environment.
Due to confidentiality obligations and client data sensitivity, the organization follows strict internal data governance policies that prohibit sending data to third-party recovery labs
Business Challenge:
During a scheduled regulatory audit and historical data verification exercise, the organization identified issues with multiple LTO backup sets that could not be accessed through standard restore procedures.
While the LTO tapes themselves were physically intact, the backup data written by enterprise backup software could not be restored due to:
- Corruption in backup catalogs
- Incompatible or unavailable backup software versions
- Errors in the backup data structure
It was determined that the issue was not a broken or physically damaged LTO tape, but an inability to interpret and extract data from the proprietary backup format stored on the tape.
Key challenges included:
- Audit deadlines with potential regulatory penalties
- Dependency on legacy or unavailable backup software
- Inability to send tapes to third-party labs due to confidentiality requirements
- Need for an in-house solution capable of parsing backup software data structures directly from LTO tapes
“ Statement from the customer:
Stellar® Data Recovery for Tape allowed us to recover highly sensitive audit data internally without compromising confidentiality. The solution played a critical role in meeting regulatory timelines while maintaining full control over client information.””
”
Solution:
The organization deployed Stellar® Data Recovery for Tape to recover data directly from the LTO backup sets without relying on the original backup application.
Rather than attempting to repair a physically broken tape or relying on the original backup application, the software was used to read and extract data from backup sets stored on LTO tapes, even when standard restore operations failed.
Stellar® Data Recovery for Tape was installed within the organization’s secure IT environment and connected to existing LTO tape drives. This enabled the internal team to:
- Read backup data directly from LTO tapes
- Parse complex backup formats created by backup applications
- Extract audit and compliance data without the original backup software
- Perform recovery entirely offline, maintaining full data confidentiality
Results:
Using Stellar® Data Recovery for Tape, the organization successfully extracted critical audit and compliance records from LTO backup sets that could not be restored using conventional methods.
Key outcomes included:
- Successful recovery of audit working papers and compliance evidence from backup software data
- Elimination of dependency on legacy or unavailable backup applications
- Zero data exposure by performing recovery entirely in-house
- Timely completion of regulatory audit requirements without penalties or delays
Conclusion:
Stellar® Data Recovery for Tape proved to be a reliable and secure solution for recovering audit-critical data from damaged LTO tapes in a highly regulated and confidentiality-driven environment.
By enabling in-house recovery, the organization preserved data sovereignty, met compliance obligations, and ensured business continuity—without the risks associated with external recovery services.
