Back up and restore management in ubuntu

Type of backups:
1)Back up of user data/specific folders
2)Back up of softwares installed on system
3)Back up of whole operating system as a Live disk

1)Back up of user data/specific folders

We know that in Linux, there is home folder under this there are some sub-folders like Pictures,Downloads,Documents,Music...This folders contain user data so we can back up this folders using following software in Ubuntu.

  • Deja-dup backup tool
     • Support for local or remote backup locations, including Amazon S3
     • Securely encrypts and compresses your data
     • Incrementally backs up, letting you restore from any particular backup
     • Schedules regular backups
     • Integrates well into your GNOME desktop

2)Back up of softwares in Ubuntu

Ways of installation of software in Ubuntu
  • Download and install softwares from Ubuntu software center

  • Using terminal with 'sudo apt-get install [s_name]

  • Using synaptic package manager.

Install aptoncd software from

Use terminal to install this software by running this command.
$ sudo apt-get install aptoncd

This software is used to make .iso file of updates/resperonities/softwares/dependencies of ubuntu which you have downloaded from internet OR installed using terminal OR installed using synaptic package manager OR installed using Ubuntu software center via INTERNET.

2.Now,whenever you install updates/resperonities/softwares/dependencies of ubuntu ....Before you shut down your computer JUST run APTonCD from System->Administration->APTonCD...than

2.(A).click on 'Create' than you will see the list of packages which you have downloaded from internet. You can add .deb packages by click on ‘Add’..

2.(B).Now click on 'Burn' ..Then select ur medium and select destination folder where .iso file will be saved....than unmark metapackage option and do not change other option and click on 'Apply'.

2.(C)Now,.iso file will be saved and APTonCD will ask for burning this .iso file to CD/DVD
.say ‘NO/CANCLE' if you dont want waste CD/DVD for it . It means your back up will be saved locally on your pc.

6. Now,Copy all .deb files to specific folder from Package folder of Mounted .iso file.

7. Unmount that .iso file.

8. Whenever your ubuntu crashed, after reinstalling ubuntu,,,Paste that folder which contain all .deb files to Desktop.
Now....Run Terminal and type
$ cd Desktop
~/Desktop$ cd [folder name]
now...type 'sudo dpkg -i *.deb' without quoets....

Here * is wild card which runs files having .deb extension...

Complete.Your all .deb files will be installed.


3)Back up of whole operating system as a Live disk

We are talking about backup of whole operating system at particular point including installed softwares,wallpapers,settings,preferences,etc as a Live disk.

This type of back up is very helpful when you are making any customized ubuntu distribution.
This can be done using one tool named as 'Remastersys'.

  • How to install 'Remastersys' tool in ubuntu ?
    Open Menu->System->Administration->Synaptic package manager and search for Remastersys and install it.

  • How to make a live disk of current installed system?

In order to learn how you can use remastersys, run
sudo remastersys
remastersys Syntax
sudo remastersys backup|clean|dist [cdfs|iso] [filename.iso]
remastersys Examples
1) to make a livecd/dvd backup of your system
sudo remastersys backup
2) to make a livecd/dvd backup and call the iso custom.iso
sudo remastersys backup custom.iso
3) to clean up temporary files of remastersys
sudo remastersys clean
4) to make a distributable livecd/dvd of your system
sudo remastersys dist
5) to make a distributable livecd/dvd filesystem only
sudo remastersys dist cdfs
6) to make a distributable iso named custom.iso but only if the cdfs is already present
sudo remastersys dist iso custom.iso
cdfs and iso options should only be used if you wish to modify something on the cd before the iso is created. An example of this would be to modify the isolinux portion of the livecd/dvd
Creating An ISO Image
To create an iso image of your installation, simply run
sudo remastersys dist
This will create an iso image called customdist.iso in the /home/remastersys directory. The dist option makes that your personal folder (e.g. /home/username) will not be included in the iso image. You might have to insert your Ubuntu installation CD during the process.
This is how the end of the process looks:

Check the size and if it is larger than 700MB you will need to burn it to a dvd
796M /home/remastersys/customdist.iso
Clean Up
After you’ve burnt the iso image onto a CD/DVD, you can run
sudo remastersys clean
to remove all temporary file created during the iso generation as well as the /home/remastersys directory.

Windows XP tricks

Creating Shutdown Icon or One Click Shutdown:

Navigate to your desktop. On the desktop, right-click and go to New, then to Shortcut (in other words, create a new shortcut). You should now see a pop-up window instructing you to enter a command line path.
Use this path in "Type Location of the Item"
SHUTDOWN -s -t 01
If the C: drive is not your local hard drive, then replace "C" with the correct letter of the hard drive. Click the "Next" button. Name the shortcut and click the "Finish" button. Now whenever you want to shut down, just click on this shortcut and you're done.

Making Google the Default Search Engine in Internet Explorer

Open registry editor by going to Start then Run and entering regedit and navigate to following three keys separately and change it as shown below:

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main]
"Search Page"=""
"Search Bar"=""
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\SearchURL]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Search]
"SearchAssistant"="" .

Modify autoplay for different types of CD

Windows XP includes the ability to perform different actions depending on the type of CD you insert into the drive. For example, you could set your system to always respond to CDs containing MP3 files by opening Windows Media Player.

To edit the Autoplay properties: Open 'my computer'. Right click on the drive you wish to set and select 'properties.' Choose the autoplay tab. Use the dropdown box to see the various recognized types of CD and choose appropriate actions for them.

Renaming The Recycle Bin icon:

To change the name of the Recycle Bin desktop icon, click Start then goto Run, write Regedit and press Enter. It opens Registry Editor. Now in Registry Editor go to:

and change the name "Recycle Bin" to whatever you want (don't type any quotes)

Locking the desktop

If you are leaving your computer for a while and do not wish to turn it off, but want to assure that no-one else can use the computer while you are away, locking the desktop is the best option.

By pressing WINDOWSKEY+L, you password protect your system just as if you had logged out or restarted the computer. The advantage is that any programs or processes that were running when you locked the desktop will stay open and running in the background, ready for you to resume work or play.

Removing Shared Documents folder From My Computer

Open registry editor by going to Start then Run and entering regedit. Once in registry, navigate to key

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Explorer \ My Computer \ NameSpace \ DelegateFolders

You must see a sub-key named {59031a47-3f72-44a7-89c5-5595fe6b30ee}. If you delete this key, you have effectively removed the my shared documents folder.

Force windows XP to reboot upon crashing

This registry edit will cause your system to reboot itself automatically upon crashing. This can be useful if you have a reason for keeping your system on 24/7:



Edit the 'AutoReboot' value to '1'

Ubuntu - 16 Cool Tips for Learning Ubuntu

1. Get lightning fast and clever at the command line
You can use keyboard shortcuts and other command line tricks to make entering commands easier and faster. You might already know about the ‘tab’ key which completes partial commands and even file and directory names.

Here are some other keyboard shortcuts you can use within terminal:

Ctrl-aMove to the start of the line.Ctrl-eMove to the end of the line.Alt-] xMoves the cursor forward to the next occurrence of x.Alt-Ctrl-] xMoves the cursor backwards to the previous occurrence of x.Ctrl-uDelete from the cursor to the beginning of the line.Ctrl-kDelete from the cursor to the end of the line.Ctrl-wDelete from the cursor to the start of the word.Ctrl-yPastes text from the clipboard.Ctrl-lClear the screen leaving the current line at the top of the screen.Ctrl-x Ctrl-uUndo the last changes. Ctrl-_Alt-rUndo all changes to the line.Alt-Ctrl-eExpand command line.Ctrl-rIncremental reverse search of history.Alt-pNon-incremental reverse search of history.!!Execute last command in history!abcExecute last command in history beginning with abc!nExecute nth command in history^abc^xyzReplace first occurrence of abc with xyz in last command and execute itAlso don’t forget to check out 4 websites where you can learn cool command line tricks

2. Launch Ubuntu Linux Applications with keyboard
There are two ways you can achieve this:

  • Use applications like Launchy or Gnome-Do that make it easier to launch applications by typing a few characters of the application’s name.

  • Or you can summon gconf editor (Alt+F2 then type gconf-editor and hit enter), and navigate to apps > metacity > global_keybindings, double click on any of the run_command_N and type in the keyboard shortcut you want to assign to an application then make a mental note of the number N. Then go to apps > metacity > keybinding_commands and double click on command_N (N being the number you used above) and type in the command you want to run. As an example if you wanted to run Firefox you would type in firefox.

Also check out these Ubuntu keyboard shortcuts you might not know about.

3. Start from wherever you left off

You can make Ubuntu remember the applications you had open when you last logged out, so that when you log back in again you’ll find all those applications running and you can resume right from where you left off.

To achieve this go to System > Preferences > Startup Applications, then go to the options tab and check "Automatically remember running applications when logging out"

4. Create a Separate Ubuntu Linux Home Partition

New versions of Ubuntu arrive every 6 months. Although you can upgrade to the latest version via the update manager, sometimes the upgrade doesn’t work as expected so some users like to do a fresh clean install.

The disadvantage with that of course is that you lose data you had in your home directory. To overcome this you can create a separate Home partition when you are installing Ubuntu, size it according to your requirements and then when you decide to install Ubuntu the next time, simply specify this partition as the Home partition (by choosing /home as the mount point).

All your files and data on the Home partition will be preserved even after a fresh install.

5. Update and Install Ubuntu Linux Software Without Internet Connection

There are lots of way to do this, the easiest of all is to use APTonCD. APTonCD allows you to create CDs and DVD’s containing all the packages you want, which you can then use to install software on computers without an internet connection.

Note that APTonCD requires you to have an internet connection (or downloaded packages) to create the installed media. However once the media is ready you don’t need an internet connection for any of the machines you want to install the software on. Insert the appropriate CD/DVD and use apt-get as you would normally.

6. Install new fonts, Microsoft fonts and improve font rendering

Ubuntu doesn’t offer many choices when it comes to the fonts. However you can easily install new fonts including those from Microsoft like Arial, Verdana, impact and many more. You can use different sites to find the kind of font you are looking for.

7. Use PPAs, Install latest versions of software

There are a lot of steps that a software has to go through before it becomes part of Ubuntu or becomes available through the Ubuntu repositories. While all those steps lend additional stability, it generally means that you don’t get the latest versions of all the software as soon as they are released.

If you like to stay on the cutting edge, you can search for Personal Package Archives for your favorite software on Launchpad and add those to your installation’s software sources. I briefly touched on PPAs and how to use them here. If that seems like too much work, you can also download the latest deb packages and install them by double clicking (you won’t get automatic updates for the software if you install it this way).

Remember you might get into an occasional trouble or two with the latest versions, but mostly it wouldn’t be catastrophic. You can always hop over to the Ubuntu Forums to get quick help.

8. Be the root

The root account is disabled by default on Ubuntu installations, mainly to prevent you from doing something you didn’t intend to do. However if you "promise to be careful" you can enable root account as follows:

  1. Type sudo passwd root and provide a root password.

  2. Then head on over to System > Administration > Login Window, go to the Security tab and check "Enable local system administrator login"

You should now be able to login as root from the Login prompt. As an alternative you can use "sudo su" to provide your password and get root prompt.

9. Run Windows applications and games

Who wouldn’t like to play Counter Strike on Ubuntu (unless of course you are completely not into it) or perhaps even run Photoshop? Well it is very much possible and here is how to do it.

10. Shorten boot time with profiling

Ubuntu Linux devs have done a great job with the boot time, Jaunty is fast and Karmic is slotted to be even faster. There is however a bit more you can do by profiling your boot. Profiling lets Ubuntu make a list of all the files that are accessed during bootup, it then sorts the files according to how they are stored on your hard disk. So the next time the system is booted, the files would be read faster.

To profile boot you need to follow these steps

  • At the grub menu highlight the kernel you boot most often.

  • Press e for edit.

  • Choose the line starting with kernel and press e again. Now add the word profile to the end of this line. Hit Enter and then press b to boot

Note that while profiling, the system will boot slower this one time, the next time however you should see an improvement. Also keep in mind that all this is machine-dependent and also depends on the arrangement of files on your hard disk, so the difference you see might not be huge, or even nil in some cases.

11. Try out different Ubuntu Linux Desktop Environments and Desktop Managers

If you are looking for something different than the default Gnome interface, you should check out alternative desktop managers that you can use. If it is a complete Desktop Environment you are looking for, KDE4 has come a long way and is now impressively usable and fun. You can do a "sudo apt-get install kubuntu-desktop" to get KDE.

12. Create a media center or a media server

It would be great if you could easily browse and manage your huge collection of music, videos and pictures. Mesmerized by Windows Media Center’s slick interface? Wait till you see what all cool options you have to turn your Ubuntu system into a media center. You can even access your media collection on your phone, PSP or a different computer if you set up a media server on your Ubuntu machine.

13. Share Firefox profile data with Windows

Many people use Windows and Linux on the same machine. If you are one of them, there would have been times you couldn’t find that bookmark you created or password you stored when you were using Firefox from within Windows. Check out how you can share Firefox profile data across operating systems without syncing it over the web (works best if you have the same version of Firefox in both OS’s). For different computers you can of course use Weave.

14. Customize Nautilus to your liking

Nautilus is the default file manager on Ubuntu. While you may be content with what it does, there is lots more you can make it do. You canuse extensions to improve functionality and even add custom functionality to Nautilus

15. Compile your own Kernel

If you can’t find something to keep you busy for the weekend and you have your customization hat on, how about building a kernel to specifically meet your requirements? This is frankly more of a learning experience. Some might say that it enables you to use just the features and drivers you require, but if everything is working fine with the kernel supplied and you don’t have any interest in the Linux kernel, skip ahead this one is not for you.

If however you require some of the experimental features of the kernel, or need it to be compiled in some other special way we say you check out this guide within Ubuntu Documentation.

16. Change Usplash Screen and create a custom splash screen for GRUB

So you didn’t count the last one? Here is another one then. A Usplash screen is Ubuntu text and a logo with a progress bar that you see when you boot up Ubuntu.

If you would like to change that to something more interesting follow these steps. What better way to show your Linux fu than customizing the very first screen that appears? You can create a custom splash screen using one of your photos, GIMP and a little tweaking. Here is the how-to.
