What is pgBackRest?

pgBackRest 2.60 now stops a restore when a page checksum is bad

pgBackRest 2.60.0, released October 18, changes a default: restore now errors and stops if a restored file has an invalid page checksum, leaving the cluster unable to start until the restore is rerun, and expire refuses to proceed if the oldest retained backup would contain checksum errors. Setting checksum-page-error=n returns to warnings. The release also adds GCS Workload Identity Federation and prefetch for object-store reads. Two weeks earlier 2.59.3 fixed a bug that could generate weak encryption subkeys and salts when system random data failed.

What is Slurm?

Slurm's newest entry is a test case, not a release; 26.05.5 is still current.

Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes. The newest feed item is a testsuite commit checking that step cancels in --stepmgr jobs record the job owner rather than root.

pgBackRest vs Slurm: editorial side-by-side

P5.0

pgBackRest 2.60 now stops a restore when a page checksum is bad

◆ Current state

pgBackRest 2.60.0, released October 18, changes a default: restore now errors and stops if a restored file has an invalid page checksum, leaving the cluster unable to start until the restore is rerun, and expire refuses to proceed if the oldest retained backup would contain checksum errors. Setting checksum-page-error=n returns to warnings. The release also adds GCS Workload Identity Federation and prefetch for object-store reads. Two weeks earlier 2.59.3 fixed a bug that could generate weak encryption subkeys and salts when system random data failed.

◆ Where it's heading

The project is moving from reporting corruption to refusing to continue past it, a stricter stance that fits the root restriction in 2.59.0. Cloud identity continues too, with GCS joining the Azure and S3 work. Underneath, the code generation, documentation tools and test harness have moved from C and Perl to Python, and a documented release schedule and new website show the project formalizing how it runs.

◆ Prediction

Patches tracking PostgreSQL 19 should continue, as 2.59.2 did with 19beta4. Now that restore can fail on checksums, expect follow-up fixes or guidance for clusters where existing backups contain them.

5.0

Slurm's newest entry is a test case, not a release; 26.05.5 is still current.

◆ Current state

Slurm maintains three branches (25.05, 25.11, 26.05). On September 2 it shipped coordinated security releases on all three fixing seven CVEs, including an operator-to-administrator privilege escalation and SQL injection via cluster names. 26.05.5 on October 13 returned to ordinary fixes. The newest feed item is a testsuite commit checking that step cancels in --stepmgr jobs record the job owner rather than root.

◆ Where it's heading

Slurm's cadence is monthly point releases on the 26.05 line with occasional coordinated security drops across all supported branches. The test commit points at accounting accuracy for step-manager jobs as current work.

◆ Prediction

A 26.05.6 point release in November is likely, possibly including the --stepmgr cancel accounting fix the new test covers.
