eratosthenes vs restic
A side-by-side editorial comparison of eratosthenes and restic — release velocity, themes, recent moves, and the top alternatives to consider.
eratosthenes vs restic: at a glance
What is eratosthenes?
eratosthenes spends 0.1.0 hardening inputs rather than adding chronology methods.
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
What is restic?
A backup tool whose roadmap is correctness, release after release
restic ships roughly two releases a year, and the changelogs are almost entirely fixes ordered by importance. The 0.19 line (June and July 2026) continues that pattern: mount safety, SFTP behavior on Windows servers, exclude handling, and exit-code semantics. New capability appears rarely and narrowly, usually as backend credential support rather than new commands.

◆ Current state
eratosthenes does Bayesian estimation of archaeological chronologies from relative sequences, absolute constraints and artifact assemblages. The 0.0.9 line built out the inference diagnostics — traceplots, histograms, batch-means MCSE reporting, displacement estimation — and then consolidated artifact probability-density estimation into a single gibbs_ad_type(). The 0.1.0 tag turns outward instead, adding validators for every user-supplied structure and replacing seq_check() with a more informative seq_diag().
◆ Where it's heading
The package is moving from research code to something a non-author can run. Consolidating estimation behind one function, then wrapping every input class in a validator, are the two steps that make failures legible instead of cryptic, and the diagnostics added earlier serve the same end for the sampler itself. Nothing in the window changes the underlying model; the work is all about making it usable and its output checkable.
◆ Prediction
With inputs validated and diagnostics in place, the next release is more likely to extend the constraint or assemblage modelling than to keep reworking the interface, though the feed's three sparse tags give little to read a cadence from.

A backup tool whose roadmap is correctness, release after release
◆ Current state
restic ships roughly two releases a year, and the changelogs are almost entirely fixes ordered by importance. The 0.19 line (June and July 2026) continues that pattern: mount safety, SFTP behavior on Windows servers, exclude handling, and exit-code semantics. New capability appears rarely and narrowly, usually as backend credential support rather than new commands.
◆ Where it's heading
The concentration of work is on the platforms where a backup tool is hardest to get right — Windows ACL inheritance and VSS metadata, macOS resource forks and FUSE mounts, SFTP and rclone backends under background execution. Running alongside that is a steady push toward being scriptable: distinct exit codes for missing source paths, snapshot removal failures and SIGINT, JSON output extended across more commands, and errors on invalid environment variables instead of silent defaults.
◆ Prediction
The next release will most likely be another 0.19.x patch of platform-specific fixes, since every minor in this window has been followed by one within a month or two.
