## What it is
A high-performance HTTP server written in Go that implements restic's REST backend API, allowing the restic backup client to store backups remotely via rest: URLs. It supports authentication via htpasswd files, append-only mode, private repositories, and Prometheus metrics.

## Use cases
- self-host a remote backup server for restic
- serve restic repositories over HTTP
- set up append-only backup storage to protect against ransomware
- give multiple users private restic repositories on one server
- expose prometheus metrics for backup server monitoring
- limit repository disk usage with a max size quota

## When to choose
- you use restic and want a dedicated, efficient remote repository server instead of generic SFTP or S3
- you need append-only storage semantics for backup immutability
- you want lightweight self-hosted backup infrastructure with per-user access control

## When to avoid
- you back up to cloud object storage like S3 or B2 directly, which restic already supports
- you need a general-purpose file server rather than a restic-specific backend
- you use a different backup tool that doesn't speak restic's REST backend API
