Open Babel vs pgBackRest
A side-by-side editorial comparison of Open Babel and pgBackRest — release velocity, themes, recent moves, and the top alternatives to consider.
Open Babel vs pgBackRest: at a glance
What is Open Babel?
Six years quiet, then a feature release and a fuzzing-driven security cleanup.
Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.
What is pgBackRest?
pgBackRest tracks PostgreSQL 19 beta by beta, patching the hangs it finds along the way.
pgBackRest is in the tail of the 2.59 cycle, which brought PostgreSQL 19 support and restricted every command except restore from running as root. The 2.59.1 patch keeps step with PostgreSQL 19beta3 and clears three defects, including a hang that occurred whenever the chunk buffer was smaller than the input buffer. Release cadence remains a few feature releases a year with patches slotted between them.

Six years quiet, then a feature release and a fuzzing-driven security cleanup.
◆ Current state
Open Babel is a chemical file format conversion and cheminformatics toolkit. After 3.1.0 in 2020 the project went effectively dormant, then returned in May 2026 with 3.2.0 — a release combining real 3D geometry work with the results of a sustained fuzzing campaign run through OSS-Fuzz, with reports from Cisco TALOS, Trail of Bits, and ADA Logics. The 3.2.1 follow-up continues that: a CVE in the MMD parser, sscanf validation across several formats, and a stack overflow in the Gaussian and cube readers.
◆ Where it's heading
The project has re-engaged around two things at once — improving initial 3D structure generation, and hardening the format parsers that make Open Babel useful in the first place. Because it reads dozens of chemical file formats, often from untrusted sources, the parser surface is the attack surface, and the release notes now devote as much space to crash fixes as to chemistry. The project says more bug-fix releases are expected through 2026.
◆ Prediction
Expect continued fuzz-driven parser fixes on the 3.2.x line, since the crash reports arrive from external infrastructure rather than a roadmap.
pgBackRest
5.0DEVOPS
pgBackRest tracks PostgreSQL 19 beta by beta, patching the hangs it finds along the way.
◆ Current state
pgBackRest is in the tail of the 2.59 cycle, which brought PostgreSQL 19 support and restricted every command except restore from running as root. The 2.59.1 patch keeps step with PostgreSQL 19beta3 and clears three defects, including a hang that occurred whenever the chunk buffer was smaller than the input buffer. Release cadence remains a few feature releases a year with patches slotted between them.
◆ Where it's heading
Two currents continue. Support for the next PostgreSQL major arrives experimentally a full release before it is needed — 18 in 2.55.0, 19 in 2.59.0, and now tracking 19's betas point by point — so the backup tool is ready before the database ships. The second is a move away from ambient privilege and toward cloud-native identity: managed identities and pod identity in place of stored keys, and the root restriction narrowing what a compromised invocation can reach. The 2.59.1 fixes are the ordinary cost of that pace, including a packaging fault in the GitHub source archives.
◆ Prediction
Expect the beta-tracking patches to continue through PostgreSQL 19's release cycle, with the next feature release arriving after 19 goes final rather than before it.
