Getting started ~~~~~~~~~~~~~~~ The :ref:`10 minute quick-start guides ` give you a first impression. Main Features ~~~~~~~~~~~~~ * **Filesystem replication** * [x] Pull & Push mode * [x] Multiple :ref:`transport modes `: TCP, TCP + TLS client auth, SSH * Advanced replication features * [x] Automatic retries for temporary network errors * [x] Automatic resumable send & receive * [x] Automatic ZFS holds during send & receive * [x] Automatic bookmark \& hold management for guaranteed incremental send & recv * [x] Encrypted raw send & receive to untrusted receivers (OpenZFS native encryption) * [ ] Compressed send & receive * **Automatic snapshot management** * [x] Periodic :ref:`filesystem snapshots ` * [x] Support for :ref:`pre- and post-snapshot hooks ` with builtins for MySQL & Postgres * [x] Flexible :ref:`pruning rule system ` * [x] Age-based fading (grandfathering scheme) * [x] Bookmarks to avoid divergence between sender and receiver * **Sophisticated Monitoring & Logging** * [x] Live progress reporting via `zrepl status` :ref:`subcommand ` * [x] Comprehensive, structured :ref:`logging ` * ``human``, ``logfmt`` and ``json`` formatting * stdout, syslog and TCP (+TLS client auth) outlets * [x] Prometheus :ref:`monitoring ` endpoint * **Maintainable implementation in Go** * [x] Cross platform * [x] Dynamic feature checking * [x] Type safe & testable code .. ATTENTION:: zrepl as well as this documentation is still under active development. There is no stability guarantee on the RPC protocol or configuration format, but we do our best to document breaking changes in the :ref:`changelog`. Contributing ~~~~~~~~~~~~ We are happy about any help we can get! * :ref:`Financial Support ` * Explore the codebase * These docs live in the ``docs/`` subdirectory * Document any non-obvious / confusing / plain broken behavior you encounter when setting up zrepl for the first time * Check the *Issues* and *Projects* sections for things to do. The `good first issues `_ and `docs `_ are suitable starting points. .. admonition:: Development Workflow :class: note The `GitHub repository `_ is where all development happens. Make sure to read the `Developer Documentation section `_ and open new issues or pull requests there.
