backupsh

Backupsh is a cross-platform backup management tool designed to orchestrate and automate data protection tasks across diverse environments, including local machines, servers, and cloud storage. It uses a declarative configuration file to describe backup sets, their sources, destinations, schedules, and retention policies, enabling administrators to define protection rules in a single place.

The tool provides a command-line interface and an optional agent or daemon component that executes backup jobs. Core concepts include backup sets, storage backends through plugins, and pre- and post-backup hooks. Backends cover local paths, network shares, SSH-accessed hosts, and cloud storage providers via plugins for S3-compatible services and major cloud platforms. Transfers and storage can be secured with encryption and authenticated access, while data integrity is supported through checksums and verification steps.

Key features include support for full and incremental backups, configurable retention and pruning policies, optional compression, and encryption in transit and at rest where supported by backends. Dry-run capability, detailed logging, and notifications aid monitoring and auditing. Scheduling can integrate with system cron or timers, or use an internal scheduler if provided. The configuration file typically defines multiple backup sets, each with sources, destinations, schedules, retention rules, and any pre/post actions.

Usage generally involves defining backup sets in the configuration, then invoking the tool to run on demand or on a schedule, with status and results reported via logs or dashboards. As a modular, community-driven project, backupsh relies on plugins for various backends, which can influence feature availability and maturity across environments.
