Hello!
Recently I found out that it should be OK for me hardware-wise to clone the hard disk which contains my servers in it. It's Ubuntu 16.04 (Desktop edition) The second part of my question (the first one I asked in previous thread) is about OS. Linux that is... As far as I know (and I'm no expert in the field)... if I make an image of the whole disk bit by bit (Clonezilla), then I shouldn't worry about making any adjustments in OS's config files. Provided that both drives are identical, of course! So it's just kinda "Plug-n-play" thing. Would be ready "out of the box", just to clone and that's it. Same disk as far as OS is concerned. But I just wanna make sure... I'll attach two pictures of disks with all the info about them.

grigory,

I can certainly recommend Clonezilla to clone your drive:

" image of the whole disk bit by bit (Clonezilla)" Actually it will try to use file by file if it has support for the filesystem by default.

The drives you show seem to have different sizes. It is easier to go from smaller to larger in most cases.


There are many ways to make and test a backup plan. Any backup is better than none.

What is different? They're both 250GB in size...

Doh, read it wronger.

What are your plans for this clone ?. To have it as a "drop-in" replacement in case the current disk fails ?.
If so, then yes it should work as planned. However what happens if this failure occurs 6 (or 12) months down the road ?. Your backup system will be waaaay out of date - especially important for a server.

Might need more thought.
