Fiber vs pgBackRest
A side-by-side editorial comparison of Fiber and pgBackRest — release velocity, themes, recent moves, and the top alternatives to consider.
Fiber vs pgBackRest: at a glance
What is Fiber?
Fiber v3 has sat in release candidate for months while v2 gets one-line patches
The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.
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.

Fiber

Fiber v3 has sat in release candidate for months while v2 gets one-line patches
◆ Current state
The feed carries two lines that barely touch. Fiber v2 receives narrow maintenance releases — a lock cleanup, an X-Real-IP backport, an HTML escaping fix, a CVE patch — most containing a single merged PR. The v3 line, last visible here at rc.3, is where the actual work is: native net/http and fasthttp handler support, Express-style request and response handlers, HostClient and LBClient in the client package.
◆ Where it's heading
v3 is the answer to Fiber's longest-standing objection, that building on fasthttp cuts a project off from the net/http middleware ecosystem. Making both handler styles native reframes Fiber as compatible rather than separate. But rc.3 dates to late 2025 and nothing newer has landed in this feed, while v2 patches keep arriving through August — a long release candidate stretch that leaves users choosing between a stable branch in pure maintenance and a v3 that has not been declared final.
◆ Prediction
The next meaningful entry is either a v3.0.0 final or a further RC; until one lands, expect the v2 line to continue receiving single-PR backports and security patches.
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.
