The people who are somehow connected with IT, sad joke goes that the users are divided into two types: those who do backups and those who began their (!) To do.If you have never experienced a complete loss of all your important documents or collections of media files, then you do not understand humor.If you come across, but could not prevent, you will also be no laughing matter.
Can you somehow prevent such unpleasant incident?Of course!But first you need to know about what a backup.
General
So called back up important files (including system).As can be understood, it is done for the sake of their protection in the event of the defeat of the operating system with a virus or a critical hardware failure.Backup can be done both manually and with the help of specialized software.
In the first case, you can copy in some lockbox important system files, while utility can save even entire operating system.
And what is the "Backup", if it is translated from the English name?The term is derived from the English word backup, which can be translated as "reserve".However, with the same success it could mean something like "backup" or "backup".Thus, this term refers to the preservation of important information on the side of the media.
way, our ancestors knew that a backup!However, this process, they do not call.Did you know that all the manuscripts were copied?The fact that the ancient enemies of love to burn the library, but because the book store all in one place and one copy would be foolish.Of course, all sorts of money-lenders also mastered the backup, maintaining lists of their debtors in several copies.
when doing backups?
Returning to the subject of proverbs should recall once again the futility of the use of mineral water in the moment when your kidneys do not work ... In short, keep all your working documents must be constantly!Even if you do not keep the computer that something incredibly important, up and running without glitches OS - in itself important information.
So before you decide to try some interesting program, it is advisable to make a backup of your important files, or that affect its performance.
easy to guess that to reinstall your operating system, it is desirable to transfer all the collections of movies and music on a spare hard drive.Program installation work almost perfectly today, but to be safe in this issue never hurts.
where you can save a backup copy?
There are two basic ways to securely store their data on their damage or total loss: the physical medium or in the "cloud."Consider all the ways in more detail, we point out their strengths and weaknesses.
record to an external drive
Since the capacity of external hard drives today can exceed the number of TB, then you can easily record a such a drive is not only some important files but even with a huge archive of photos and videos.The advantage of this method is not only a huge capacity of the media, but his mobility.The only major drawback is the possibility of losing data due to mechanical influences on the disc.To avoid this, the housing becomes more reliable.
Flash Drive
If you want to save only some of the system files, then for this purpose would be enough and the flash drive.They are cheap, with each year of their capacity is only growing, there are no problems with the drivers, and the mechanical reliability of the mark.Moreover, even entering into the water usually does not damage the files that are recorded there.
disadvantage is that flash quite often fail, and some utilities that might warn of the likelihood of such events is not there.This is especially true of cheap Chinese models.Recording speed is very low, and the data retention time is also limited.
Setting the flash drive in a drawer for six months, you may well find that it is nothing.Especially those suffering drives a large volume, which still has not learned how to effectively deal with the leakage of charge.
CDs
Despite the anachronism of this type of media in some cases they are simply irreplaceable.Of course, we do not encourage you to use CD-blanks to 700 MB, but a DVD-9, with a capacity of about 9 GB, can be a good way out.Keep in mind that the discs should be protected from extremes of temperature, sunlight and mechanical defects.
If we talk about an acceptable reliability and capacity, it is best proven it is DVD.Blank CD is extremely reliable and durable, but 700 MB for these days is ridiculous.Blu-ray discs is very roomy (30 GB and above), but the drive for recording and reading are not in every computer.Moreover, they are very sensitive to surface damage.
«Clouds»
this topic in recent years has become a incredibly popular.So what is a backup in the "cloud"?It - copying the necessary files on the servers of third-party companies that specialize in the provision of the space available for a fee or free of charge.
most famous "clouds" are services from Dropbox, Google Drive and Yandex Disc.For example, Google Drive for free give as much as 15 GB of free space, which is quite enough for most home users.
How to create a backup copy of Windows?
If you ever had the dubious fortune to work on Windows 98 / Me, the well remember their "paduchesti."More precisely, the system itself was quite good, but at the slightest foul of compatibility with some programs and devices were able to go into the deep "swoon", which had all the chances to end up reinstalling the operating system.
Fortunately, new versions of Microsoft has provided a built-in backup mechanism.In Vista / 7/8, he was brought up quite decent condition.Consider a backup of Windows 7. Make it easy.
Click on "Start" button, find the point where the "Control Panel."In the dialog box, track down "Backup and recovery."Click the link the left mouse button, and the dialog box, select "Create a system image".
newly opened working window in which you can choose just three ways to save the image on your hard drive, to disc CD / DVD, on a network.Check the box opposite the preferred item, then click on "OK".If the Internet connection is poor, then the attempt to save the image in the network may fail.
Of course, all the same thing can be done using third-party backup utilities.The most famous are the products from Acronis, Norton Ghost.The home is also ample functionality of specialized programs of the package Nero.Their disadvantage is that these utilities are paid.
Of course, if you require high reliability, it is better to pay.But even home users have enough of standard means Vindovs.
Mobile devices
All this in one degree or another for sure is familiar to everyone who worked on the computer though a little long time.But what do the owners of today's popular tablets and smartphones?
After all these devices now kept weight is extremely important information that losing would not be desirable.Since today is the most widely used mobile operating system "Android", talk about the gadgets under its control.

What is the Root?
Why not simply copy important data without resorting to such tricks?The fact that the operating system from Google is an "open" only in words.In fact, the case that the user does not have full access to the file system of your device.Moreover, empowerment is not even in many programs, and therefore no Root-rights do not succeed.
Brief information about Titanium Backup
Now let's talk about the program Titanium Backup.There are paid and free versions, and for ordinary users would be enough opportunities for free software.
little about its installation

create a backup
And now we know how to make a backup of Android smartphone or tablet.Once again: in no case do not engage any option if you do not know exactly about their destination.Thus, the utility started.What to do next?
In the upper part of the working window there is a button "Backups".After clicking it will open a dialog box "Backup."It should be an item on the full backup of user data, programs and settings.On the contrary it has a "Start" button, which you have to press.

Very often it happens when you have received incorrect Root-law.We can not elaborate on this process, as it is different for each type of smartphone or tablet, but we want to warn against the use of questionable programs, "Ruth in a single click."As a general rule, anything sensible, they can not do.
What to do in case of data loss?

However, sometimes you may need recovery backup to a single program.To do this, go to "Backup" and then celebrate his flag.After that you should click on the "Restore" and then wait for some time.
What other backup software exist?
a good alternative to the above application is a backup program for TWRP Recovery.It has a fairly simple and austere interface, but quite decent functionality.In addition, the menu of this utility to quickly understand even not very experienced users.
