Rclone Monitor

What

Recursively monitors a directory for new files and moves them to cloud storage via Rclone.

Why

Accessing cloud storage is very slow compared to local storage. Automation tools like Sonarr do not deal well with slow storage while importing and can be rendered unusable until the import completes. A better method is to stage the files locally and move them to cloud storage using an external tool. This is that external tool.

Requirements

A working Rclone installation and Python 3+ with the watchdog module installed.

Installation

Download or clone this repo. Make rclone-monitor.py accessible somewhere in your PATH, like /usr/local/bin/rclone-monitor.py. Run pip install -r requirements.txt

If you use SystemD, there is an example unit file included. Edit rclone-monitor.service to suite your needs, then copy to /etc/systemd/system/rclone-monitor.service. Run systemctl daemon-reload and systemctl start rclone-monitor.service. You can monitor output by running journalctl -f -u rclone-monitor.service. Once you are satisfied it's working, run systemctl enable rclone-monitor.service so that it starts upon bootup.

Usage

usage: rclone-monitor.py [-h] [-e EXECUTABLE] [-f RCLONE_FLAG] [-l LOGLEVEL] [-p POLLING] [-s] [--debug] src dst

Monitor staging directory and move files to rclone backend

positional arguments:
  src                   Source directory to monitor for new files (i.e. /mnt/staging)
  dst                   Rclone target location (i.e. gdrive:/)

optional arguments:
  -h, --help            show this help message and exit
  -e EXECUTABLE, --executable EXECUTABLE
                        Rclone executable (default: "rclone" in PATH)
  -f RCLONE_FLAG, --rclone-flag RCLONE_FLAG
                        Append global flag to Rclone command (see
                        https://rclone.org/flags/) (list of flags always set:
                        ['progress', 'stats=10s', 'no-traverse', 'user-

                        Chrome/74.0.3729.131 Safari/537.36"'])
  -l LOGLEVEL, --loglevel LOGLEVEL
                        Logging output level (valid options are "DEBUG",
                        "INFO", "WARNING", "ERROR", and "CRITICAL") (default:
                        INFO)
  -p POLLING, --polling POLLING
                        Seconds to wait for more data to be written to file
                        before proceeding with Rclone move (default: 60)
  -s, --scan-existing   Scan for existing files upon startup
  --debug               Show debugging output
