[Discuss] full disk backups

[Timothy Lyons]

I assumed some level of competence in setting up  storage (local or cloud) with at-rest encryption - while also encrypting the backup.

Secure: Restic uses cryptography to guarantee confidentiality and integrity of your data. The location where the backup data is stored is assumed to be an untrusted environment (e.g. a shared space where others like system administrators are able to access your backups). Restic is built to secure your data<https://restic.readthedocs.io/en/latest/100_references.html#design> against such attackers, by encrypting it with AES-256 in counter mode and authenticating it using Poly1305-AES.

My requirements dictated a mobility-enabled solution.  Cloud fits that bill perfectly - for me.  But, I've also spent the last 6-years securing large-scale enterprise-cloud in one form or another. 😉  It's all about what works for the user.

Kindest Regards,

Sorry... but... the terms "backup", "secure" and "cloud" do not belong
in the same sentence. If it's in a public cloud then it can be
compromised by a third party bad actor. Witness the Code Spaces breach.
Not saying you shouldn't use public cloud storage; saying you should be
cautious in your trust of it.

On the subject of Clonezilla: it's not a backup tool. It's an imaging
tool. It can be used as part of a backup system: the physical volume
analogue to copying a virtual machine's vdisk files to other storage.
Using it this way is cumbersome on Linux systems where realistically
the only thing that needs a low-level copy is the boot block of the
boot device and that only once. It would be more useful on a dual-boot
Windows/Linux machine using Clonezilla command line to clone the
Windows system volumes.
