What is containerd?

containerd is walking checkpoint/restore back across every branch it still supports.

Five branches remain in active service and they move as one. The August 12 pair — 2.2.7 and 2.3.4, cut three minutes apart — disables checkpoint restore in CreateContainer by default behind an experimental config flag and formally deprecates it, the same removal the 2.4 beta already made outright. CRIU codepaths now stay dark unless CRIU is installed, and CRI gains non-UTF-8 binary environment variable support.

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.

containerd vs pgBackRest: editorial side-by-side

C5.0

containerd is walking checkpoint/restore back across every branch it still supports.

◆ Current state

Five branches remain in active service and they move as one. The August 12 pair — 2.2.7 and 2.3.4, cut three minutes apart — disables checkpoint restore in CreateContainer by default behind an experimental config flag and formally deprecates it, the same removal the 2.4 beta already made outright. CRIU codepaths now stay dark unless CRIU is installed, and CRI gains non-UTF-8 binary environment variable support.

◆ Where it's heading

The project is retiring a feature by degrees rather than at a version boundary: removed in the 2.4 pre-release, defaulted off and deprecated in the maintained lines, with an opt-in escape hatch for anyone who depended on it. That pattern — decide on the development line, then propagate the same decision as a default change everywhere else — is how containerd is handling anything with a security or correctness argument behind it.

◆ Prediction

Expect the deprecation to complete in a later 2.4 or 2.5 release with the configuration option removed entirely, and expect the next coordinated patch batch to land on all five branches within the same hour, as every batch this quarter has.

P5.0

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.
