Barman vs Fiber
A side-by-side editorial comparison of Barman and Fiber — release velocity, themes, recent moves, and the top alternatives to consider.
Barman vs Fiber: at a glance
What is Barman?
Barman 3.20.1 closes a CVE that let a writable catalog delete unrelated snapshots.
Barman 3.20.1 fixes CVE-2026-93853: Barman trusted snapshot IDs from the backup catalog, so anyone able to overwrite backup.info could make it delete unrelated cloud snapshots with Barman's own credentials. It now checks snapshot names against provider metadata before deleting. 3.20.0 in August raised the Python floor to 3.12 and added SSE-C encryption, parallel GCS uploads and S3 Outposts support.
What is Fiber?
Fiber marks its v2 module deprecated in favour of v3
Fiber's v2 line has been on narrow maintenance for months: lock cleanup, an X-Real-IP backport, HTML escaping, a CVE patch. v2.52.16 formally marks the fiber/v2 module as deprecated in favour of v3 and fixes CORS wildcard origins that accepted empty subdomain labels. The v3 line, last visible in this feed at rc.3, carries native net/http and fasthttp handler support and Express-style handlers.

Barman
0.0DEVOPS
Barman 3.20.1 closes a CVE that let a writable catalog delete unrelated snapshots.
◆ Current state
Barman 3.20.1 fixes CVE-2026-93853: Barman trusted snapshot IDs from the backup catalog, so anyone able to overwrite backup.info could make it delete unrelated cloud snapshots with Barman's own credentials. It now checks snapshot names against provider metadata before deleting. 3.20.0 in August raised the Python floor to 3.12 and added SSE-C encryption, parallel GCS uploads and S3 Outposts support.
◆ Where it's heading
After closing the cloud backup-and-restore loop in 3.18 and 3.19, Barman is hardening it for regulated, least-privilege setups: customer-supplied keys, data kept on Outposts, and now a fix aimed exactly at deployments where the uploading identity has fewer rights than Barman. Releases come roughly every two to three months.
◆ Prediction
A 3.21.0 feature release is the likely next step on the usual cadence, probably continuing cloud storage and retention safety work.
Fiber
2.5DEVOPS
Fiber marks its v2 module deprecated in favour of v3
◆ Current state
Fiber's v2 line has been on narrow maintenance for months: lock cleanup, an X-Real-IP backport, HTML escaping, a CVE patch. v2.52.16 formally marks the fiber/v2 module as deprecated in favour of v3 and fixes CORS wildcard origins that accepted empty subdomain labels. The v3 line, last visible in this feed at rc.3, carries native net/http and fasthttp handler support and Express-style handlers.
◆ Where it's heading
The deprecation notice tells v2 users to plan their move. With v2 patches shrinking to one or two pull requests, active development sits entirely on v3.
◆ Prediction
Further v2 releases are likely to be security fixes only; the feed does not show v3's current state past rc.3.
