One more on disaster recovery.
ReHi to all. this is as much in response to a newbie user's concern about "not finding a Linux disaster recovery app."
Preamble:
I am attaching it here as JJJCr was the original poster here, and so, using that to try and keep all the posts as intact as possible.
Since this was for a newbie user, I think it is of importance to address the approach he/she will need to adopt to find what they need effectively.
Generally, my experience tells us all that so very often our worst enemy is our own impatience, yet that also is all to exposed to being opportinized - caveat emtor in respect of an eternal catch-22, yet be not daunted as it can be regulated ongoing, ardour and all, on which I am about to elaborate...
====================================
[QUOTE=JJJCR;5022089]for the reference of others who might encounter same issue.
i manage to get my GUI back by typing: Xorg -configure
a new file was generated on this location /root/xorg.conf.new
I copied xorg.conf.new to /etc/X11/ and replace xorg.conf (note X in X11 is capital)
after replacing the xorg.conf my GUI was okay.
But I have an issue on the fstab, don't know how to edit.[/QUOTE]

Linux disaster Recovery Strategies:
====================
There is no "one click fits all" answer for this, however disaster recovery software does exist, along with many defensive strategies to contend with disasters.
Simply put and warned: "Rome was not built in a day!"
That said, one sees the problems associated with facing one's challenges in many reality-challenged manners!
On the other hand, that is no licence for anyone to opportunise any challenge, problem or failing of another, especially when so doing proves deleterious (or generally detrimental to the common good.)
Defusing that issue is one thing the internet can do so very well in every subject imagineable, but all is out there, so caveat emtor.
Now for the "packages":
"REAR" or relax and recover is one of many that you might find in the repos for your distro, however there are surely many more repose at your disposal than just the ones that came with the original installation, and that may well prove where these enhanced software tools turn up.
Another tactic I use (albeit much more hardware intensive) is to use a combination of USB3 RAID boxes and one or more NAS boxes and or NAS servers, such as openmediavault. the latter is based on Debian, but still works on an old triple boot machine as a big and scaleable NAS box, so to speak.
While all this might sound a tad scary, "faint heart never won fair lady", albeit centuries old, also apples here ad hoc. Hence faced with a challenge, or challenge itself, out own impatience is often our worst enemy, yet as with all of "the good, the bad and the ugly", anything can be opportunized at any juncture, so, once again, caveat emtor - as it were the "catch 22 of the fair lady".
For this approach, I use filezilla, but well tweaked and heavily filtered.
Second, I put very little data in the LVM. this is for 2 reasons:
1) Since the machine is likely to be set to dual or triple boot, each OS is installed in its own independent physical hard drive, so that they are kept hardware separated.
2) With Fedora, I expect to install a new version every 6 months, more or less. I would not want to have to reload some 8 Tb. of data into each new LVM every 6 months! That would take far too long from my machine's work time.
Instead, the data is kept in a local set of drives, and backed up in various ways, mostly by the use of Filezilla, which is set to handle 4 transfers at a time and do a lot of garbage filtering at the same time.
also, in that same process, I pre-segregate ongoing, what is for archival so it ends up via another FTP job, going to a separate external drive, ultimately sitting in a Hard drive dock (I call them "toasters"). Once loaded there, the drive can be powered down and put on the shelf, saving its working life.
for longer storage,m I can either burn to disks or preserve the archival drive in a metal box, custom made with a special steel of very high magnetic permeability, constructed to cause the earth's magnetic field to curcumvent the drive in storage.
This is an extreme defense, but sometimes extreme needs do occur.
If I then need to reload from the archives, I can use Filezilla to read the archival drive back in the "Toaster" into the active data drives as needed.
Now, shopping for that new machine, (and a laptop is never to be ones first machine!) I locate the box, power supply and hard drives I will need. If they are available from the merchant that I intend to use to do the installation, I will buy from him. If not, I will buy where I can best get what I want from this items (of course one needs to know what has any hope of working with what,m but for those items it is a lot simpler than in regard to the processor, motherboard and RAM.)
Next, I will bring all this together at the service counter of the merchant or dealer who I want to do the installation and startup. then, we will choose the motherboard, processor and RAM, in person, and his technicians can do the rest. In Montreal, I may have to leave a deposit and they will order in the parts, then assemble and start up, usually taking about a week or so.
I then get a phone call to advise it is ready, go there, pay any unpaid balance and pick it all up.
Note: when I make the order, I make it expressly clear that I expect to pay for the installation service, and effectively am accepting that because it makes them responsible for any malfunctions, D.O.A. (which has a typical 2% chance of occurring) etc. to me this is a simple "insurance policy" upon the existence/availability of which is predicated the intent to purchase itself, up front and fully forthright!
Then, once it is all up and proven running, I can upgrade to fill my whole needs, not having the need to pay for more service than I really need.
If I should ever encounter a merchant who is less than proactively willing to undertake this degree of attendant responsibility, to myself, I say, yet again, "caveat emtor".
Logically, "Let a word to the wise be sufficient!"
Then, with a solid router (suggest Netgear's nighthawk series for domestic use, but for business or bigger situations there are business class devices, but not always seen advertised on the consumer market). (Note, I do not accept any form of compensation or monetisation for my mention of anything of a proprietary nature, so as to maintain my independence and non-beholding fastidious and pristeen.)
