[Shrinkarr](https://github.com/Dan6erbond/shrinkarr) is a support tool
for the \*Arr stack, that can automatically delete torrents by size or
completion date once a given free space threshold has been reached.
Users can limit the categories that Shrinkarr is allowed to remove.

While other tools such as
[Prunerr](https://github.com/rpatterson/prunerr) already exist to only
remove torrents that have been upgraded in the \*Arr apps. However,
sometimes the \*Arr apps and download client don't share the same
disk, in which case you might want a simpler approach of deleting
items once a certain free space threshold has been reached.

Once you provide the configuration either as a `.env` file or by
setting environment variables manually, Shrinkarr will go through
qBittorrent's downloads and find either the oldest by completion date
or largest and remove those if the free space threshold has been
reached.

Shrinkarr can be run with Python or Docker:

    # With Python

    # Install dependencies, only needed once
    $ python3 -m pip install -r requirements.txt
    # Run Shrinkarr
    $ python3 -m shrinkarr.main

    # With Docker

    $ docker run shrinkarr:latest

    # With Docker, self-managed CRON, every five minutes

    $ docker run shrinkarr:latest --entrypoint 'cron'

The Docker image hasn't been published yet. So currently users need to
build their own or use the Python script directly.

Sample `.env` file:

    SHRINKARR_QBIT_HOST=https://qbit.example.com/
    SHRINKARR_QBIT_USER=admin
    SHRINKARR_QBIT_PASSWORD=""
    SHRINKARR_MONITOR_PATH=/mnt/media
    SHRINKARR_FREE_SPACE=250GB
    SHRINKARR_ALLOWED_CATEGORIES=tv-sonarr,radarr

Why not use QBit_Manage which lets you set seedtime rules by tracker,
category, and more, and will auto-prune non-hardlinked files by
specified tracker, and do a heck of a lot more?

Honestly because I didn't know it existed and looking at it I can't
really figure out how I can configure it to do what I want but I might
need to give it a more in-depth look. My solution is simple and clean.

Given the name, I thought this would be something like dynamically
shifting downloads to a compressed filesystem to save disk space or
something.

Getting really sick of everyone piggybacking off of the \*arr name for
their little helper scripts that have nothing to do with the Servarr
suite of apps forked from Sonarr.

thanks for sharing! any other extensions/plugins you can think of

This is what I use too. By far the superior solution. Ultimately
anything I have hardlinked I continue to seed because it takes up next
to no space.

Anything not hardlinked gets removed after seed times have been met.

I just use deluge's autoremove plus.

​

I thought this was some cool compression system to keep disk space
available for seeding longer

In my case the categories is how I control it to only remove non-
hardlinked files. Sonarr and Radarr copy things over to the NAS so
those files need to be removed from qBit when the drive starts getting
full. But I get that checking if a file is hardlinked is a very
elegant solution, too.

To be honest I agree. But I also didn't know how else to name it since
Prunerr was already taken, and a short name improves discoverability.

Your completed files folder can be on the nas, seeding from there,
while the files get hardlinked to your libraries.
