Elden Ring SeamlessCoop Backup Manager for Steam Deck

A bash utility for managing backups of Elden Ring SeamlessCoop saves.

Motivation

Managing SeamlessCoop versions on Steam Deck has a few challenges, such as needing to backup and transfer your saves after each upgrade. Backups keep your saves safe in the event of an upgrade failure, while transfers are required to play old saves on new versions of SeamlessCoop (a new compatdata directory is created for each version of SeamlessCoop added to your Steam library).

I got tired of sshing into my deck to manage backups. I even had a few failed upgrades resulting in save file loss. It's possible for files/data to be removed by Steam as part of official Deck updates, creating the need for backups to be stored off the deck as well.

Requirements

This guide assumes you have basic terminal knowledge. Additionally, you will need:

• gum
• direnv
• an ssh-enabled steam deck

This script written and tested using bash on macOS.

Usage

Environment setup

Create a copy of .envrc.sample that you export using direnv:

cp .envrc.sample .envrc

Modify the .envrc based on the directions therein. Once done, lets make the environment variables available to our script:

direnv allow .

Note

Anytime you change your .envrc, you will need to run direnv allow . again.

Finding your compatdata dir

If you're unsure where your saves are stored on your deck, you won't be able to fill your COMPATDATA_ID_<SeamlessCoop version> variable in your .envrc. The backup manager comes with a way to find all Elden Ring directories on your deck, including the compatdata dirs.

TODO

• Create new backups
• Synchronize backups to a local machine
• List all relevant compatdata dirs
• Transfer backups from one version of SeamlessCoop to another
• Generalize script to work with any game on Steam Deck
