Backup Security and Compliance with Bareos
Bareos is open-source backup and recovery software with features for protecting backup data, controlling administrative access and verifying data integrity. It supports TLS-encrypted communication, client-side encryption and signing, checksums, role-based access control, retention policies, WORM media and offline tape.
These capabilities can support technical and organizational measures related to GDPR, NIS2, DORA and internal data-protection policies.
Protecting Data in Transit and at Rest
TLS Transport Encryption: Communication between Bareos components can be protected using TLS encryption, helping secure backup data while it is transferred across the network.
Client-Side Encryption and Signing: File data can be encrypted and digitally signed by the Bareos File Daemon before it is transferred to the storage system. During recovery, signatures can be checked to detect modifications.
Checksums and Verification: Bareos supports file signatures, checksums and verification jobs to identify changes or corruption in backup data. Regular restore tests help confirm that data can be recovered when needed.
Access Control and Secure Storage
Controlled Administrative Access: Authentication, access control lists and console profiles can restrict which commands and Bareos resources are available to individual users.
Retention Management: Separate retention settings can be defined for files, jobs and backup volumes. These settings help manage how long backup records and stored data remain available.
WORM and Offline Tape: Bareos supports WORM tape media. Removable tape can also be stored offline or separately from production systems as part of a ransomware-resistant backup strategy.transparency and reduces dependence on undocumented proprietary backup formats.
Open and Transparent Architecture
Public Source Code: Bareos is licensed under the AGPLv3, and its source code is publicly available for review, testing and integration.
PostgreSQL Backup Catalog: Bareos uses PostgreSQL to store metadata about backup jobs, files, clients, volumes and storage locations. This information supports administration, search and recovery.
Documented Storage Format: The storage format used by the Bareos Storage Daemon is publicly documented. This provides transparency and reduces dependence on undocumented proprietary backup formats.
Certifications and Compliance
Data Protection and Integrity: Encryption, digital signatures, checksums, verification jobs and restore testing can support measures for protecting the confidentiality and integrity of backup data.
Access and Retention Controls: Restricted administrative access, configurable retention and separated storage can support internal security policies and regulatory requirements.
Documented Backup Operations: The Bareos catalog and job logs provide records of backup, verification and restore activities that can support operational reviews and documentation.
