Which other disk backup solution do you recommend other than Clonezilla?
2 years ago by tiz to c/selfhosted
I’m going to make a backup of 2TB SSD today. I will use clonezilla mainly because that’s all I know. But do you recommend any other ways for any reason?
I want to keep the process simple and easy. And I will likely take backup once a month or so repeatedly. It doesn’t have to be ready all the time. If you need more clarification, ask away.
I did a thing like this but with a ios command that wrote the disk to image and piped it to ssh but then piped it back to a waiting drive. It was great as you could pull the disk and boot right off it. Do you know if that can be done with dd?
Does the data change a lot? Does it need to be a block-based backup (e.g. bootable)? Otherwise, you could go with rsync or restic or borg to only refresh your backup copy with the changed files. This should be far quicker than taking a complete backup of the whole SSD.
You can use Rescuezilla which is basically a GUI fir Clonezilla, but easier to use 😋
My method requires that the drives be plugged in at all times, but it's completely automatic.
I use rsync from a central 'backups' container that pulls folders from other containers and machines. These are organized in
/BACKUPS/(machine/container)_hostname/...
The /BACKUPS/ folder is then pushed to an offsite container I have sitting at a friends place across town.
For example, I backup my home folder on my desktop which looks like this on the backup container
/BACKUPS/Machine_Apollo/home/dork/
This setup is not impervious to bitflips a far as I'm aware (it has never happened). If a bit flip happens upstream, it will be pushed to backups and become irrecoverable.
I recommend it over a full disk backup because I can automate it. I can't automate full disk backups as I can't run dd reliably from a system that is itself already running.
It's mostly just to ensure that I have config files and other stuff I've spent years building be available in the case of a total collapse so I don't have to rebuilt from scratch. In the case of containers, those have snapshots. Anytime I'm working on one, I drop a snapshot first so I can revert if it breaks. That's essentially a full disk backup but it's exclusive to containers.
edit: if your goal is to minimize downtime in case of disk failure, you could just use RAID

Can't you do a snapshot like VSS does on windows and back that up on a running system? I assume with a filesystem that supports snapshots that would be possible.
I’m on a similar boat except I might have less time resource available in the future cause I’m getting a job.
Hopefully I could automate full disk backup because if something like Immich breaks, I can just load up from the backup drive. My family also use the services so… I think it’s great you brought up RAID but I believe when Immich or any software mess things up it’s not recoverable right?

RAID is not a backup, no. It's redundancy. It'll keep your service up and running in the case of a disk failure and allow you to swap in a new disk with no data loss. I don't know how Immich works but I would put it in a container and drop a snapshot anytime I were to update it so if it breaks I can just revert.

It's faster and more efficient than just dd :)
Borg for files. Proxmox snapshots for the VMs.
Veeam endpoint free version is nice because it doesn't require a reboot.
I personally use Borg to do automatic backups.

dd if=/dev/sda0 conv=sync,noerror bs=128K status=progress | gzip -c file.gzYou can add an additional pipe in there if you need to ssh it to another machine if you don't have room on the original.
