Release highlights
Backup lifecycle management
PBM now supports backup retention policies based on the grandfather-father-son (GFS) model. Configure retention periods in the lifecycle section, then apply the policy with pbm cleanup --lifecycle. For a deep dive into this feature, see the documentation
[Experimental feature] Parallel uploads to Google Cloud Storage
- Parallel uploads rely on an experimental feature of the Google Cloud Storage Go client. The upstream project does not recommend this feature for production use, and its API can change in future releases.
- For upstream limitations, see Parallel uploads in the Google Cloud Storage Go client
PBM can upload parts of a backup to GCS concurrently and compose them into the final backup object. Parallel uploads may improve throughput for large objects, depending on the available bandwidth and host resources. For more insights into this feature, see the documentation.
Extended platform support
PBM 2.16.0 adds support for these platforms:
- Debian 13 (Trixie)
- Red Hat Enterprise Linux 10
Upgrade considerations
S3 debug logging
PBM now validates storage.s3.debugLogLevels for Amazon Simple Storage Service (Amazon S3) and S3-compatible storage. If the configuration contains an unsupported value, PBM cannot initialize the storage and reports an error. For detailed information about these options, refer to the documentation
Service management on Red Hat platforms
Red Hat packages no longer include SysV init scripts. If your automation uses these scripts to manage pbm-agent, update it to use systemd before upgrading.
Deprecated HMAC client for GCS
Removed the HMAC-based client for Google Cloud Storage. PBM no longer recognizes HMAC configuration options for GCS. Before upgrading to PBM 2.16.0, reconfigure GCS storage to use the native JSON client and service account credentials.
