Proper way to backup entire OS with Linux Ubuntu settings?

Question

linux

I have a hard 2 OS, through GRUB I choose which one to use. How to make a full backup of Linux, so that if the hard one flew, you could raise everything with all the settings?

Answer 1

clonezilla.org

Answer 2

Acronis Live is the easiest and fastest way.

Answer 3

Boot from a flash drive and make a binary copy of the OS partition to a file on a separate disk. You can even in graphical mode through Gnome disks.
I use BTRFS, so I take snapshots and backups directly from the running OS, but if you don’t have BTRFS, you will have to tinker a bit to transfer to a new file system.

Answer 4

I usually do, rsyncbut sometimes with a partial transfer (i.e. full backup, partial unpacking) I use tar
Try it, you won't regret it:

$ man rsync
$ man tar

Answer 5

If it's just a full-full backup, then dd. True, the backup will take the size of exactly the entire hard drive and it will be possible to restore only to a device with the same parameters. Well, or mount the image and pull out the data.
If it's a little less than full, then dump/restore
is usually enough to have a homework backup and /etc - well, also /usr/local/etc - for those who are their own installers. But for a quick recovery, it's better to have a complete image.
UPD: The comment indicates how you can compress the resulting image and send it to a remote machine. There is nothing surprising about this method - the standard UNIX mechanism for passing stdout

By analogy. Accordingly, consider only when deploying that the configs are somewhat in other places.
And so I use the stage4 gent to drag one Ubuntu between laptops with 6.06, for example. And sometimes I also carry virtual machines.

Answer 7

We used to have a server on hetzner and they used tartarus there. I also used it there, and once I had to restore the data, everything worked out fine with the system. It is only necessary to save the subd separately.

Answer 8

Are you sure you need a full backup of your home machine? A backup of the home folder is quite enough for me (because the message archives are there, etc.), and just a list of installed packages (more precisely, a list of software that I use at least once a year, and not a list of all packages in general). Now much can be backed up a little more cunningly - synchronization. For example, for Firefox, I have a synchronization server on another machine, and this is essentially a backup of the entire Firefox profile. Mail via IMAP - i.e. letters on the server that is being backed up, plus a local copy of the letters in the mail client is obtained. And if you look like that, many personal data can be somehow backed up like this.

Answer 9

Take a look at fsarchiver. Backup both files and partitions. Of the advantages, the ability to mount archives as vd.
