I made quite a search through all the engines I know on several languages but haven't actually found the exact "done-by-someone-already" solution. I wan't to BU a system by FS with .tar and --exclude's(thats why not xcat or dd) and then make a bootable .iso to expand on different machine which would partition the disc automatically or would promt for it. + mbr of course, maybe just by dd. Or either that would just be a regular boot-only .iso and I would slipp the .tar from external device or by network. Any idea of how to and how better to would be appreciated, in case someone done anything similar.

I would check into SysResCD. Specifically, adding your own data to it (your backups), and using "autorun scripts" written in shell that would restore/create an MBR and un-tar your backups.

Look at this section of the website:

http://www.sysresccd.org/Sysresccd-m...SystemRescueCd

It talks of disaster recovery on a remote server. Much of the discussion is about PXE booting which it sounds like you don't need, but the general discussion parts about the recovery process are relevant.

Yea, this is not exactly what I want. It is all about the PXE. And, not going into details, I want it to work exactly the ways I mention: all-in-one installer from .tar with FS or standart bootable .iso + me slipping it the .tar but then I don't really know how to manage paritioning and mbr on the hdd/sdd of the new systems, I am going to unpack it to.

I'll bump once, in hope to get 1-2 more tips.

sadly what you are looking for i have never seen. the closest to something like you are looking for involves creating a kickstart image. this will not be a backup of a continuous system, but think of it like a ghost image from pointA, but nothing more.

i dont think that will solve the problem the way you are looking for. sorry, but its as close as I can come up with.

in the past I have just typically performed backups on the system files that are unique to the server and the data/application(s) files for restoration. i have used both encrypted tar as well as just straight rsync, depending on the backup medium and storage capacity. the restoration this way is not horrid, but does require a fresh OS install or at least a similar OS already installed before you can perform the restoration from the backup media.
