Lorean is a simple and user-friendly backup management tool written in Python using Flask.
You can easily create, manage and restore backups which are still human readable and can be easily modified. Technically, you could also call it "over-engineered file copying app".
Warning
This is by no means a well-tested and bulletproof backup system. Always make sure to follow the 3-2-1 backup rule, do not put full trust into this program if the data being backed up is critical and make sure your recovery strategy works.
See LICENSE. This software comes with ABSOLUTELY NO WARRANTY.
Note
This software has been written when I was around 15 years old and may contain severe code quality and usability issues; even though it was mildly improved in mid to late 2025, functionality may still be limited.
Lorean has some advantages compared to just copying and pasting your folders, such as:
Specify paths that are unnecessary to back up (for example, node_modules or similar) which
Lorean will skip over to save tons of time and storage. This can be achieved using regular
expressions, offering you a huge variety of filtering mechanisms at your fingertips.
You can monitor the validity of your backups using the Lorean backup manager; it will warn you about suspicious anomalies and problems regarding your saved files, so you won't easily make things worse when recovering from a backup.
Lorean creates verbose and user-customizable logs that explain what was going on in each backup process, which files have been skipped and what might've gone wrong, so you can lean back and let your backup run in the background, close your browser or whatever you like to do - later, you will find everything noted down in the logs.
Create a folder on your removable drive, add it in the Lorean settings and the rest doesn't have to be your business - Lorean manages everything regarding your file structure under the hood, but if you need it, each backup is still human-readable and can be easily used to copy and paste files from without performing a full recovery.
It isn't a hassle to work with Lorean, it's actually super simple; you start the app, visit the web interface in your browser and enjoy the user-friendly interface.
