Advice on making a full snapshot/backup of a running Linux system (Debian)

Hi all,

I’m looking for advice re making a full snapshot/backup of a running Linux system (Debian).

In an ideal world, should an issue occur, I would like to be able to load a live USB with the backup, boot and write from that.

Timeshift seems to be an option but I’m wondering how the above would work in my case. A few questions.

1. My disk is fully encrypted with LUKS. Would this pose a problem?

2. I would like to write my backups to a veracrypt container. Would this pose any issue? I’m not sure how I would boot from a live USB in this case I could not decrypt the USB.

Essentially I’d like a step-by-step guide to backing up my full system (including all files in home) in such a way that I can easily roll back should the worst happen. Do any of you know of such a guide or can perhaps offer some help?
