If encountered, but could not prevent, you will not be laughing.

When to do a backup?

Returning to the subject of Proverbs and sayings, it should again be reminded of the futility of the use of mineral water in that moment, when your kidneys don't work anymore… simply put, to keep all their working documents necessary to constantly! Even if you do not keep on your computer is something incredibly important that is configured and working without glitches OS – is in itself important information.

So before you decide to try out some interesting software, it is advisable to do a backup of your system or important files that affect its performance.

Easy to guess that before the complete reinstallation of the OS, it is desirable to transfer all your collection of movies and music on a spare hard disk. Setup is now working almost flawlessly, but to be safe in such a matter never hurts.

Where to save the backup?

There are two main ways to securely save your data from damage or total loss: on physical media, or in “cloud”. Consider all the methods in detail, point out their strengths and weaknesses.

Record to the external drive

As the capacity of external drives today can exceed several TB, you can easily write on the disk not only some important files, but even with a huge archive of photos and videos. The advantage of this method is not only huge storage capacity, but also its mobility. The only serious drawback is the possibility of losing data due to strong mechanical impacts to the disk. To avoid this, purchase a more robust case.

Flash drive

If you only want to keep some system files, for this purpose, it is enough for the flash drive. They are cheap, every year, their capacity is only growing, no problems with the drivers and the mechanical reliability on top. Moreover, even getting in the water often does not harm the files that are there recorded.

The Drawback is that the flash drive quite often fail, and some utilities that could have warned of the likelihood of such events, is not there. This is especially true of cheap Chinese models. Write speed is very low, and the data storage time is also limited.

Putting the flash drive in a drawer for six months, you may well find that there's nothing there. Especially it affects the storage of a large volume, still have not learned how to effectively deal with the leakage of the charge.

CDs

Despite the anachronism of this kind of media, in some cases they are simply irreplaceable. Of course, we do not encourage you to use a CD-blanks 700 MB, DVD-9, with a capacity of almost 9 GB, can be a good way out. Keep in mind that burned discs should be protected from extremes of temperature, sunlight and mechanical defects.

If we talk about acceptable reliability and capacity, it is best proven that is DVD. CD extremely reliable and durable, but 700 MB in these times is ridiculous. Blu-ray disc is very large (30GB or more), but drives for writing and reading are not in every computer. In addition, they are very sensitive to surface damage.

“Cloud”

This theme in recent years has been simply incredibly popular. So what is backup in “cloud”? It – copying all necessary files on the servers of third party companies specializing inproviding some free space for a fee or free of charge.

The Most famous “clouds” are services from Dropbox, Google Drive and Yandex Disc. For example, in Google Drive completely free of charge as much as 15 GB of free space, which is enough for most home users.

How to backup Windows?

If you ever had the dubious fortune to work with Windows 98/Me, then remember their “aduceti”. More precisely, the system was quite good, but at the slightest trouble in compatibility with some programs and devices were able to go into a deep ‘syncope’, and had a chance to end up reinstalling the OS.

Fortunately, the new versions of Microsoft provided a built-in backup mechanism. In Vista/7/8 it was in quite decent condition. Consider backup Windows 7. To make it simple.

Click “start”, look for the item “control Panel”. In the dialog box, find the “Backup and restore”. Click the left mouse button and in the dialog that appears, select “create a system image”.

Again will open the window where you can choose from three ways to save images: on the hard disk, CD/DVD, network. Check the box next to the preferred item, and then click “OK”. If the Internet connection is poor, try to save the image in the network could fail.

Of Course, all the same can be done using third-party tools copy. The best known are the products from Acronis, Norton Ghost. In the home also will be more than enough, the functionality of specialized software from Nero. Their disadvantage is that all these utilities are paid.

Of Course, if you need increased reliability, it is better to pay. But home users will even be enough of standard means of vindovs.

Mobile devices

All of the above in varying degrees, certainly familiar to anyone who worked on the computer for any long period of time. But what do the owners of today's popular tablets and smartphones?

After all, these devices today houses a lot of extremely important information to lose that you absolutely do not want. As of today, the most widely used is the mobile OS “Android”, let's talk about the gadgets under its control.

So how to backup Android devices? In advance stipulate that the copy we will not banal photos and videos and programs and settings. If to lose it all, then restore all the information will require more than one hour.

First, consider the example of a work of great utility Titanium Backup. With its help you can easily save all files and settings of the mobile OS “Android”. This is extremely important, as the backup of the device is often able to save your personal data and applications settings for online banking. Needless to say, as this may help.

What do I need to backup?

This requires two things:

• Make Root. Of course, occasionally come across smartphones and tablets, which already “rouchovany” by the manufacturer, but in most cases you will have to do it yourself;
• Utility Titanium Backup.

Why need Root?

Why not just copy the important data, without resorting to such tricks? The fact that the OS from Google is “open” only. In fact, it happens so that the user does not have full access to the file system of their device. Moreover, extended rights, even in many programs, and because right do not succeed.

Quick details of Titanium Backup

Now let's talk about the program Titanium Backup. There are free and paid versions, and for ordinary users will be enough opportunities free programs.

A Little about its installation

If I use the program from the memory card, do not forget to set in your device's settings option which permits this. The installation itself does not take much time. After the first run, the tool will ask you for root access. Don't forget to click ‘Resolve”, simultaneously clicking the check box “Remember”.

We Remind that the program features will be enough for removing your device from the system, so carefully read the comments for each menu, do not press all the buttons in a row.

Create a backup

Now we will learn how to backup your Android smartphone or tablet. Once again we remind you: in any case, do not use any option if you do not know about their purpose. So, the utility started. What to do next?

At the top of the program window there is a button «Backup». After clicking it will open a dialog box “Backup”. It should be the point of complete copying of user data, programs and settings. Opposite it there is a button “start” that should be clicked.

A dialog box Appears in which the user can select those programs that wants to keep. Click on the button “Start batch processing applications». Just have to wait until there is backup Android. Timecopy depends on the number of installed programs and the power of your device.

After the process is complete you will again throw out the window, where there will be a full list of all created backups. Look at the symbol on the right side: if there is no exclamation marks, all went well. If they are, then something in the copy process went wrong.

Very often this happens when you incorrectly got Root-rights. We can't give more details about this process, as it varies for each type of smartphones or tablets, but I want to caution against the use of questionable programs “Ruth in just one click”. As a rule, nothing sensible they can do.

What to do in case of data loss?

How to restore a backup, deploying it on the device, if some problem has occurred?

Make it quite easy. Again go to menu “Processing”, click on “Recovery”. Opens a dialog box in which it is better to choose "Restore all data”, so that your phone or tablet back to a fully functional state, which was lost due to some external reasons.

However, sometimes you may need to restore a backup of a single program. To do this, go to the section “Backup”, and then mark it with the check box. After that, press the button “Recovery”, and then some time to wait.

What other backup utilities are available?

A Good alternative to the above described application is a program for backup TWRP Recovery. It is relatively simple and austere interface, but quite decent functionality. In addition, in menu this utility will quickly understand even a not too experienced user.

In the first dialog box, just click on the button Backup and then get into the menu backup. Note the checkmarks next to all of the pertinent items, and then click on the Swipe to Back Up.

Making a backup of the tablet as saving important data, it is best to choose Dropbox (its support is “out of the box) or a computer hard drive. We recommend you to choose the media due to the large size of the resulting image, which simply may not fit on the memory card of the device.

To restore the system from a previously created copy is required in the main program window, click the Restore button. As in the previous case, you can restore the whole system and some programs by clicking on the checkboxes next to their names.

As you can see, creating a backup using this tool, you can not call such a complex action.

Finally, note a remarkable program Helium. As her “progenitor" of the Periodic System, the utility is extremely easy and simple. The interface is completely Russified, so additional hints on its development are required. Before you make a backup of the firmware with it, you will also have to become Root for full access to file system of the device.
