How and with what can you make a full backup of the system (Debian) so that you can quickly deploy it elsewhere?

Question

linux

Due to the fact that fault tolerance is never 100%, I would like to know from experienced people how best to implement a subject?
Now mysql and downloaded files are backed up on S3, but it will take me about 2-3 hours to deploy them on a new server, including installing the necessary software.
As an option, I’m considering Puppet or a banal script on fabric, but it will take quite a lot of time + I don’t remember exactly what was installed.
Is there a way to store a full system dump and recover from it in 10-10 minutes?
And accordingly how to configure DNS for this?

Answer 1

If Amazon or something similar, then create your own AMI and attach EBS with data to it.
If you have access to the server, then Clonezilla.
You can create your own iso with the necessary packages in Suse Studio (or by hand).
To set highly individual settings on top of the image, you can also roll the script.

Answer 2

And what prevents to archive the entire partition with the system and throw it on another server from where it can be deployed if necessary? At one time, I had just such backups on Klodo and they deployed back without any problems. (although they were deployed to the same virtual machine and I can’t say how such a backup will behave when changing the hardware configuration)

Answer 3

I use the dump/restore utility. Although I was asked to think that this technology does not care about integrity at the time of performing atomic operations.

Answer 4

See duplicity. You can make a full dump of the partition + knows how to incrementally and upload it to s3 itself
