Barman vs Bun: at a glance
What is Barman?
Barman's cloud lifecycle is closed; 3.20.0 starts hardening it for regulated storage.
The arc that ran through 3.18.0 (block-level incremental backups written straight to object storage) and 3.19.0 (restoring from that storage with the standard restore command) is complete. 3.20.0 works the edges of it: SSE-C server-side encryption with customer-supplied keys across every barman-cloud command, parallel uploads to Google Cloud Storage, S3 access point ARNs including S3 on Outposts, and EBS snapshots kept on the Outpost rather than the parent region. A new check-archived-wal-range command reports gaps in the WAL archive, and the minimum Python is now 3.12.
What is Bun?
Bun 1.4.4 adds bun fmt, a built-in Prettier-compatible formatter, two weeks after bun check.
Bun now covers formatting as well as type checking: v1.4.4 ships bun fmt, a Prettier-compatible formatter it says is 3-6x faster than oxfmt, and makes bun check 1.4-7.8x faster on large projects. The same release closes 271 issues, migrates Yarn Berry lockfiles, adds install retries with backoff, and cuts Bun.SQL CPU per query by up to 48%.

Barman
2.5DEVOPS
Barman's cloud lifecycle is closed; 3.20.0 starts hardening it for regulated storage.
◆ Current state
The arc that ran through 3.18.0 (block-level incremental backups written straight to object storage) and 3.19.0 (restoring from that storage with the standard restore command) is complete. 3.20.0 works the edges of it: SSE-C server-side encryption with customer-supplied keys across every barman-cloud command, parallel uploads to Google Cloud Storage, S3 access point ARNs including S3 on Outposts, and EBS snapshots kept on the Outpost rather than the parent region. A new check-archived-wal-range command reports gaps in the WAL archive, and the minimum Python is now 3.12.
◆ Where it's heading
With backup and restore both working against object storage, the work has moved to the requirements that decide whether a regulated shop can adopt it — who holds the encryption keys, whether data stays in a given location, and whether the archive can be proven complete. The inactive-server handling that began in 3.17.0 also continues: barman cron now stops WAL receivers left streaming on servers switched to active = false, and command behaviour on those servers has been made consistent, with commands that ingest new data still rejected.
◆ Prediction
The Outposts and SSE-C work points toward more storage-backend and residency coverage rather than new backup mechanics. A 3.20.x patch settling the Python 3.12 floor or the new access-point handling is the more likely near-term release.
Bun
6.3DEVOPS
Bun 1.4.4 adds bun fmt, a built-in Prettier-compatible formatter, two weeks after bun check.
◆ Current state
Bun now covers formatting as well as type checking: v1.4.4 ships bun fmt, a Prettier-compatible formatter it says is 3-6x faster than oxfmt, and makes bun check 1.4-7.8x faster on large projects. The same release closes 271 issues, migrates Yarn Berry lockfiles, adds install retries with backoff, and cuts Bun.SQL CPU per query by up to 48%.
◆ Where it's heading
After the Rust rewrite in July and bun check in v1.4.3, Bun is absorbing the remaining steps of a TypeScript toolchain one release at a time. Package-manager reliability work (Yarn Berry migration, retries, faster hoisted installs) shows it is also going after teams still on other package managers.
◆ Prediction
Expect a linter or lint mode next to round out the check/fmt pair, and more lockfile migrations aimed at pnpm and Yarn users.
