NCUploader

NCUploader is a modern Python tool for managing file uploads to Nextcloud servers with retention policy management. It provides a seamless way to automate the process of uploading files and directories to Nextcloud while maintaining control over how long they should be retained.

Features

• Upload files and directories to Nextcloud
• Track uploaded files with a local index
• Apply retention policies (e.g., remove files 30 days after upload)
• Simple YAML configuration
• Load credentials from .env file for better security
• Colorized terminal output
• Comprehensive logging
• Command-line interface

Requirements

• Python 3.12+
• Nextcloud server
• nc_py_api library

Installation

# Using uv (recommended)
uv pip install ncuploader

# Using pip
pip install ncuploader

Configuration

NCUploader uses a YAML configuration file to define upload sources, destinations, and retention policies:

# ncuploader.yaml
nextcloud:
  url: "https://your-nextcloud-instance.com"
  username: "your_username"
  password: "your_password"  # Consider using .env file instead

uploads:
  - local_path: "~/path/to/local/file.txt"  # ~ is expanded to your home directory
    remote_path: "/remote/destination/file.txt"
    retention_policy:
      delete_after_upload: "30d"  # Supported formats: Xd (days), Xw (weeks), Xm (months)
  
  - local_path: "~/path/to/local/directory"  # ~ is expanded to your home directory
    remote_path: "/remote/destination/directory"
    retention_policy:
      delete_after_upload: "2w"

Using .env for Credentials

For better security, you can use a .env file to store your credentials:

# .env
NEXTCLOUD_URL=https://your-nextcloud-instance.com
NEXTCLOUD_USERNAME=your_username
NEXTCLOUD_PASSWORD=your_super_secret_password
# NEXTCLOUD_TOKEN=your_super_secret_token  # Alternative to password

Then, your YAML config can omit sensitive information:

# ncuploader.yaml (credentials loaded from .env)
nextcloud:
  # Credentials loaded from .env file
  
uploads:
  - local_path: "~/path/to/local/file.txt"  # ~ is expanded to your home directory
    remote_path: "/remote/destination/file.txt"
    retention_policy:
      delete_after_upload: "30d"

Usage

Command Line

# Upload using the default config file (ncuploader.yaml in current directory)
ncuploader

# Specify a custom config file
ncuploader --config /path/to/config.yaml

# Run in dry-run mode (no actual uploads or deletions)
ncuploader --dry-run

# Show verbose output
ncuploader --verbose

Environment Variables

In addition to using a .env file, you can also use environment variables directly:

export NEXTCLOUD_URL="https://your-nextcloud-instance.com"
export NEXTCLOUD_USERNAME="your_username"
export NEXTCLOUD_PASSWORD="your_password"

How It Works

1. NCUploader reads your YAML configuration file
2. It loads credentials from .env file or environment variables
3. It loads the existing index of previously uploaded files
4. For each path in your configuration:
   • If not in the index: uploads to Nextcloud and adds to the index
   • If already in the index: checks the retention policy and removes if needed
5. The index is updated with the current state
