qBt Migrate

This tool changes the root paths of existing torrents in qBittorrent. It can also convert slashes when migrating between Windows and Linux/Mac.

Usage

Install from PyPi using pip, or jump to Examples for Docker

pip install qbt_migrate

Run the script and follow prompts or use CLI arguments with command qbt_migrate

usage: qbt_migrate [-h] [-e EXISTING_PATH] [-n NEW_PATH] [-r] [-t {Windows,Linux,Mac}] [-b BT_BACKUP_PATH] [-s] [-l {DEBUG,INFO}]

optional arguments:
  -h, --help            show this help message and exit
  -e EXISTING_PATH, --existing-path EXISTING_PATH
                        Existing root of path to look for.
  -n NEW_PATH, --new-path NEW_PATH
                        New root path to replace existing root path with.
  -r, --regex           Existing and New paths are regex patterns with capture groups.
  -t {Windows,Linux,Mac}, --target-os {Windows,Linux,Mac}
                        Target OS (converts slashes). Default will auto-detect if conversion is needed based on existing vs new.
  -b BT_BACKUP_PATH, --bt-backup-path BT_BACKUP_PATH
                        BT_backup Path Override.
  -s, --skip-bad-files  Skips bad .fastresume files instead of exiting. Default behavior is to exit.
  -l {DEBUG,INFO}, --log-level {DEBUG,INFO}
                        Log Level, Default is INFO.

By default, everything happens in the BT_backup directory defined by the OS the script is running on. Override BT_backup path if needed.

Default BT_backup paths:

• Windows: %LOCALAPPDATA%/qBittorrent/BT_backup
• Linux/Mac: $HOME/.local/share/data/qBittorrent/BT_backup

A backup zip archive is automatically created in the BT_backup directory.

Examples

Assuming all of our torrents are in X:\Torrents when coming from Windows, or /torrents when coming from Linux/Mac

NOTE: When running qbt_migrate on a Linux/Mac machine, Windows paths will require double \. Ex. C:\\Users\\user\\Downloads\\Torrents

NOTE: Take note of trailing slash replacement when changing from Windows <-> Linux. -e X:\ -n /torrents will result in /torrentsxxxxx, not /torrents/xxxxx. The correct pattern for this would be -e X: -n /torrents or -e X:\ -n /torrents/.

qbt_migrate -e X:\ -n Z:\ -t Windows  # Windows to Windows (Drive letter change)
qbt_migrate -e X:\Torrents -n X:\NewDir\Torrents -t Windows  # Windows to Windows (Directory Change)
qbt_migrate -e X:\Torrents -n Z:\NewDir\Torrents -t Windows  # Windows to Windows (Drive letter change with directory change)
qbt_migrate -e X: -n /torrents -t Linux  # Windows to Linux/Mac (converts slashes)  # When running on Linux machine \\ is needed for Windows Paths  # Note Trailing Slash
qbt_migrate -e X:\Torrents -n /torrents -t Linux  # Windows to Linux/Mac (converts slashes)  # When running on Linux machine \\ is needed for Windows Paths
qbt_migrate -e X:\\Torrents -n /torrents -t Linux  # Windows to Linux/Mac (converts slashes)  # When running on Linux machine \\ is needed for Windows Paths

qbt_migrate -e /torrents -n /new/path/for/torrents  # Changes torrent root path on Linux/Mac
qbt_migrate -e /torrents -n Z:\Torrents -t Windows  # Linux/Mac to Windows (converts slashes)
qbt_migrate -e /torrents -n Z:\\Torrents -t Windows  # Linux/Mac to Windows (converts slashes)  # When running on Linux machine \\ is needed for Windows Paths

# Adavanced Usage with RegEx
# Example would replace /some/test/with/a/path with /test/matched/path
qbt_migrate -r -e /some/(\w+)/.*$ -n \1/path -t Linux  # Matches using regex patterns and replaces using capture groups.
qbt_migrate --regex -e /some/(\w+)/.*$ -n \1/matched/path -t Linux  # Matches using regex patterns and replaces using capture groups.

Docker

You can also run this tool with Docker if you don't have Python, or don't want to install the package to your system directly. The BT_backup path is automatically overridden to /tmp/BT_backup, so mount your BT_backup there.

NOTE: When running qbt_migrate Docker image on a Linux/Mac machine, Windows paths will require double \. Ex. C:\\Users\\user\\Downloads\\Torrents

The Docker image has all functionality as the pip install, following the same arguments/patterns listed in the above examples.

For example, mounting in the default BT_backup path on a Windows machine running Docker

docker run -v %LOCALAPPDATA%/qBittorrent/BT_backup:/tmp/BT_backup jslay88/qbt_migrate -e X:\ -n Z:\  # Windows to Windows (Drive letter change)
docker run -v %LOCALAPPDATA%/qBittorrent/BT_backup:/tmp/BT_backup jslay88/qbt_migrate -e X:\Torrents -n X:\NewDir\Torrents -t Windows  # Windows to Windows (Directory Change)
...

Mounting in the default BT_backup path on a Linux/Mac machine running Docker

docker run -v $HOME/.local/share/data/qBittorrent/BT_backup:/tmp/BT_backup jslay88/qbt_migrate -e X:\ -n Z:\  # Windows to Windows (Drive letter change)
docker run -v $HOME/.local/share/data/qBittorrent/BT_backup:/tmp/BT_backup jslay88/qbt_migrate -e X:\Torrents -n X:\NewDir\Torrents -t Windows  # Windows to Windows (Directory Change)
...

If for some reason you wanted to override BT_backup path from /tmp/BT_backup within the container, simply set environment variable BT_BACKUP_PATH on the container to where you will be mounting in.

The -e for environment variable override must go before the image jslay88/qbt_migrate as the -e after the image is for --existing-path

docker run -v %LOCALAPPDATA%/qBittorrent/BT_backup:/opt/qbt_migrate/fastresume -e BT_BACKUP_PATH=/opt/qbt_migrate/fastresume jslay88/qbt_migrate -e X:\ -n Z:\  # Windows to Windows (Drive letter change)
...

You can also clone this repository, build the image, and run your own built image

docker build . -t qbt_migrate
docker run -v %LOCALAPPDATA%/qBittorrent/BT_backup:/tmp/BT_backup qbt_migrate -e X:\ -n Z:\  # Windows to Windows (Drive letter change)
...
