General :: How To Totally Back Up System OS
Jun 24, 2011
Our company had a vendor doing some data transformation work for us that we recently decided to take in house. They were good enough to transfer all their processes to a pc we gave them and it's running great. Only thing is that its a linux OS and I have no idea how to do anything other than what to click on to run programs.
Its OS version 2.6.34.8-68.fc13.i686.PAE. KDE SC version:4.5.5
I know that at the bottom left where there would be a windows button on a Windows PC there is a blue K button. That's ALL I know.
First thing I'd like to know is how to totally back up this system OS and all so that if something happens I can load it onto another PC. I'm pretty panicked because it IS an old pc it's on. Then, I'd like to know what is this exactly and how can I learn what I have here

I have an acer aspire one with Linpus Lite. Copied a document into OO yesterday and got a message OO had crashed. OO window wouldn't close etc. Emails and internet still worked ok. When closing down, emails & internet closed ok. Tried Ctrl, Alt Del to close the crashed OO file - didn't work. Eventually turned machine off at main switch. Today when turning machine on, goes past the screen advertising Acer Aspire one, but then nothing else happens, no icons. Black screen with a cross as a cursor. Cross is a diagonal cross, thicker than an ordinary x. Nothing like I have ever seen before.

slightly embaressing but luckily I had firefox open at the time. I have managed to delete my panel at the bottom of my screen and I'm totally stumped as to how to get it back.I'm pretty new to linux, having dabbled with it in the past.. finding it much better than said mainstream OS *Ahem* .The reason I deleted it by accident was I right clicked on it and deleted panel thinking I'd just added another panel to it. D'oh. My firefox isn't touching the top of the screen either, I think I created a panel up there but I can't see it or anything

OpenSUSE 11.2 x86_64
Kernel 2.6.33-34.1(from Kernel:HEAD repo)
KDE 4.4.1
Did the daily set of updates today, which included the kernel, but that update only had to do with enabling IPV6 on all flavors of the kernel. The update also included updates to the xorg packages from the X11:XOrg repo. However I was prompted that a requirement couldn't be met and one of the options was to downgrade xorg-x11-driver-input to the previous revision (not previous version). I thought that wouldn't matter so I did it.
I reboot and I am able to choose the kernel I want in the grub boot screen, get to the KDM login screen, however, after that the input is totally dead! Mouse and keyboard don't work whatsoever. I have a Logitech Cordless Desktop Wave mouse (LX8) & keyboard so I tried it with a standard PS/2 wired mouse & keyboard but it produced the same exact problem.

This is a IBM T23 (10 years old)pentium3 1.1ghz640mb ram28gb hdd (contianing several bad sectors)intel graphicseverything works out of box (graphics, wireless, etc) on a live cdhowever after installation, upon boot, it displays "Error loading operating system" right after BIOS and before even goes into GRUB and is stuck there.Enter live cd, and choosing boot from harddrive does not solve the problem.Already did the CD check, which shows no problemdid a bit googlingturned out this could be an issue with a dying harddriveand sadly, it is the case, the harddrive on this 10 year old laptop is indeed dying D:However, installing windows xp posed no problem... (altho tons of driver issue, but anyways...)I have a few solutions in mind1). just use a usb stick as the replacement for harddrive2). get a new harddrive (not even sure what to get for this laptop D: )3). find a magical way to fix it :SWould definitely be glad to know a way to load this system on this existing harddrive for nowI was told earlier that there are ways to tell the system to avoid mapping the bad sectors.

I want to start totally from scratch on Linux server I installed the other day. No dual boot, no personal files, etc... on it.
Fdisk -l shows the following:
Disk /dev/sda: 320g
255 heads, 63 sectors/track, 38913 cylanders
units = cylanders of 16065 *512 = 822...bytes
[code]....
All the info I have found has multiple steps, but in my situation is there just 1 easy command to do this? If not, can I just reinstall from CD and it will reformat and let me customize more? If I have to use the several steps to reformat, can you explicitly type out exact commands for me? I am completely new, have to learn all this, and all the referece books/materials kind of scatter the info around.

I have a Linux system running (Debian). It is working perfectly from a remote point of view. I can ssh in it, it has the imap running correctly, and a couple of kvm systems running (I can also ssh to them). Well, it works!
But when I go in front of the keyboard/mouse/screen there's nothing. No way to switch between the consoles with Ctrl+Alt+F# (X is not running on this system). The screen is desperately black. But the screen does not go to sleep mode, it still has its green led on! I guess it means that the graphics card still sends the H and V syncs correctly (VGA connection).
Is there a process that is blocking the display and prevents me from getting the control?
Note: Last time I used the console, it was in console 1. Ctrl+Alt+F1.

I tried the restore disks that I created when I got the laptop, but the problem persists. s there a way to delete this Backtrack from the system and go back to Windows 7?

A friend lent me their Ubuntu book but I can't understand it and could not find anything about the sound suddenly going from the speaker on Monday night. I went to Sony Ericsson's site to check something on my account and loud music suddenly started blaring out so I pressed the Fn button and End which muted it. However, I forgot to take it off before closing down for the night and as of Tuesday morning I have no sound. Would me leaving mute on all night have screwed something up or has it just suddenly gone? I am so upset as I cannot afford to get another laptop as not working and this is my last resort since my original Compaq one died.
I appreciate any "Helpful" solutions. Not in techy but layman's terms please as I won't understand. Also if you do reply, I am in the UK and also don't get notifications so I am not being rude if I can't get back to you quickly. I will be going to bed now.

I have a centos5.3 server. I want to configure it as transparent squid proxy server. Internet is connected to eth0(192.168.0.100) and lan is connected to eth1(192.168.200.0/24) and eth1 ip is 192.168.200.1 .
I have configured it as dhcp,squid and its working fine.
Now I want to configure it as a transparent,so that no one has to manually configure in browser.
I just added a line
Code:
http_port 3128 transparent
to make it transparent.
Now while adding nat rules,
Quote:
iptables -t nat -A PREROUTING -i eth1 -p tcp --dport 80 -j REDIRECT --to-port 3128
code....
Internet is totally blocked on eth1. And after stopping the firewall the internet comes.

I have an Acer Aspire 6930g with an nVidia GeForce 9300m GS which has a broken screen. I have been using an external monitor for some time using Linux Mint, without issue.
I initially set this up with great difficulty using the small parts of the screen that would still display an image at the time. Now, however the screen is totally dead, I have since disconnected the laptop monitor in order to not cause issues.
The issue I am currently having is trying to use live distros.
I'll give you example: I boot ubuntu 9.10 32bit and it gets to the initial boot menu. I choose "Try Ubuntu..." It shows the loading screen. Screen goes blank when going to desktop
I tried Ctrl+Alt+F1 to get to a terminal, but the screen stays blank. The same thing happens with both Knoppix and Backtrack 4 as well. The display goes blank upon switching to the desktop.

I start up my laptop, and it works great for about an hour but then it starts to make a loud scratching sound and I know that sound is my HD and after I have to shut it down (by holding the power button), it takes a few tries to get it to boot normally. So I'm pretty sure my HD is the problem, so my question is how can I back up my system (I'm running Ubuntu 10.4)? Just in case something really bad happens. I remember there was a thread sometime ago and a guy there said something about a program that would create a iso of the whole system, and it would back up everything even programs and stuff. So can anyone help me with this? (Btw the search feature is not working for me) Also if you wanna buy me a new HD you can do that too XD.

I just did do a search on this subject but couldn't really find what I was looking for.At the moment I have a perfectly running system and I would like to make a copy / back-up from that so in case somethings happens I can always place it back as if nothings happened.

I have a 2TB USB drive which I use as a backup device - I dump two filesystems onto it, totalling around 1TB. However, doing the dump trashes my F11 system, making it basically unusable, not only during the dump but also afterwards. I have 8GB of RAM, all of which is needed and normally in use, but when dumping, the system starts hogging huge amounts of it as buffer space - up to 1GB of RAM is reported to be allocated. And rather than using free memory for buffer space, it seems to aggressively swap processes out to get it. The system tends to melt down as a result, and just switching virtual desktops can take 5 minutes.
But after the dumps finish, the problems continue - the system is currently trying to keep around 700-800MB free, and continually swapping out processes to do so, even after the buffer space in use has gone back to about 100MB. This seems like strange behaviour for a fairly common type of activity. Presumably a lot of the buffer space is used to store what is being read from the filesystem (which will never be needed again), and some is used to cache the writes to the USB drive which is slower than the internal hard drives.
I have spent a lot of time trying changes to some of the kernel parameters, after reading articles about them. Of all the ones I've tried, setting vm.dirty_ratio to 1 instead of 5 helps a bit, and setting vm.dirty_background_ratio to 5 instead of 20 makes some improvement I think. Setting vm.swappiness to 0 doesn't seem to help at all.
So my question (at last!) is - how can I back up my filesystems without my system dying? In particular, can I limit the space used for buffers somehow, or turn off buffering for the dump process? And why does dumping result in the system artificially keeping huge amounts of space free afterwards, so I have to reboot to make the system usuable again?

A member suggested I install Samba (to be able to print to a Windows computer's printer).
I added Samba clients and support files using Add/Remove Software.
I rebooted, and found that the Printers choice in System/Administration had disappeared.
Could someone please suggest how I can get the Printers choice back? maybe a Terminal command to run the Printers config app so I can add a network printer?

over here on my desktop I have KDE 4.6.4 running, updated from 4.6.0 through all intermediate steps. In the last few days I feel, that it got a bit unstable and I think, I have messed it up again, with doing some stupid things in the repository management. But of course, I donīt remember what I did...
So I am asking myself, if I could reset the system to the state where it came from: KDE 4.6.0, including all the updates from the standard openSUSE repositories.
I would do it as follows:
1. deactivate the additional KDE repositories and X11 from OBS (I needed it for installing xbindkeys)
2. switch packages to the standard repositories, which came with openSUSE, and also switch the packages to Packman
3. run an update, or how it is called, the switch back to 4.6.0
would this work, or would I completly mess the system up?
I then would leave it like it is, with the only additional repoīs: Packman

I'm planning on dual booting my netbook with Windows 7 and UNR.However, given that I don't have a DVD drive to back up my system I was wondering if the "Backup Partition" on my harddrive (which as far as I know, was pre-installed) is the same as these disks.Now another problem lies in what happens if all goes south. Do I lose all three partitions? (Ubuntu, Windows, Backup).I suppose that wouldn't be end of the world. I still have another (main) computer running Vista. Still...
I've dual booted my Vista before and while the main job went withou major incident...I do have a bad history of screwing up one or both partitions.Also, will GRUB still work okay with Windows 7? I'd hate to install UNR and then have the boot loader not let me into one (or both OSes).Without the recovery disks I don't really have a safety net. I do have an external, but it already has stuff on it (my Mac HDD finally gave out, and the ext is a mirror of the HDD as death, which is stuff I do not want to lose). So as a last question (in case you know the answer) will backing up NetBook's HDD using the Windows Backup create a new folder of backup in the external, or use the entire external?
