A Python tool to handle clean read-only (re-)syncs of
[Seafile](https://www.seafile.com) libraries with the intention to mirror them.
## Overview
If you have Seafile libraries, you may want to back them up in a safe place
automatically.
One option is to snapshot/backup the whole server on which the library is
stored. However, in some situations, this may not be feasible or even not
possible.
This is why this repository offers a different way: you can define one or
multiple Seafile libraries that shall be downloaded to a local directory. These
libraries can belong to the same or a different user, and even on different
Seafile servers!
## Features
* Download/sync defined libraries in customisable intervals
* De-sync libaries immediately after they have been downloaded to avoid sync
errors
* Allow to force-re-sync a library even if its re-sync interval hasn't reached
yet
* Extensive informative and error logging
* Created with automation in mind so you can run it in cronjobs or systemd
triggers
* Deal with the numerous caveats of `seaf-cli` and Seafile in general
## Install
The tool depends on the following applications:
*`Python 3` and its library `yaml`
* [`seafile-cli`](https://help.seafile.com/syncing_client/linux-cli/), available e.g. in [Debian](https://packages.debian.org/bullseye/seafile-cli)
You can execute the tool with `python3 seafile_mirror.py`. The `--help` flag
informs you about the required and available commands.
There is also an [Ansible
role](https://src.mehl.mx/mxmehl/seafile-mirror-ansible) that takes care of
installing the tool, setting up a systemd service, and running it daily.
To keep the Seafile daemon that is required for `seafile-cli` running in the background, check out this [exemplary systemd service](examples/seaf-daemon.service).
## Configuration
Configuration is done in a YAML file called `seafile_mirror.conf.yaml`. You can find an example [here](examples/seafile_mirror.conf.yaml).
If that configuration file resides in the same location as the `seafile_mirror.py` file you are running, you should provide `--configdir ./`.
## Logging and caching
The tool creates `seafile_mirror.log` in addition to the log to the standard
output. With `-v` you can print DEBUG messages that will help you in case of
problems.
It also caches the current status of synced libraries and their latest full
download in the file `.seafile_mirror.db.json`. Do not delete this file unless
you don't mind that the tool will re-sync all libraries in the next run.
