The need to protect personal data for a long time, no one doubts. Thus, a joint survey by Gartner 15% of the computers are broken within the first year, and 22% - for the first five years of use. What this means for the user? Let's start with the fact that the failure of the computer always unpleasant - modern man is becoming increasingly difficult to do without his trusty assistant - PC. However, if you can easily fix a broken computer or buy a new one, then restore the lost data is not easy. According to the same statistics agency Gartner, most burned hard drives can not be reversed, and that means that all your data - documents, photos, music, movies and more - will be lost, it is necessary only to your winchester fail. But upset about it is not necessary, as it is not necessary to sit on their hands. Neither one nor the other will not help you recover the data or prevent their loss. But what really helps, because it is a reliable backup program. If you have no idea what is backed up, you should read through the article to the end, to be completely sure what kind of program you need, and that it should be able to do. So, the backup program is a system utility that allows you to create backup copies stored on your computer data. Backups serve as a guarantee that in the event of equipment failure your data will remain safe and sound. Typically, such a program works as follows. You choose what data would want to protect, and the program will copy them to your preferred location. This can be a CD or a remote FTP server. The latter option is preferable as a backup involves off-site storage of backup data. Simply put - out put, take a closer look.
Here, you may wonder why you can not copy manually?
You can manually copy the data, but compared to the manual copying of professional backup (from the English back up - to protect, cover) the program has a lot of advantages, each of which is worth more detail. Copying scheduled backup main advantage of the program compared with manual copying is the ability to Scheduled Backup. This means that a user-specified time, the program automatically starts to copy the data.
For example, you want to copy the data every Friday at 6:00 pm. To do this, you just specify the day and time. All the program does the rest by itself. Background copy the backup program runs in the background as a service Windows. This means that the whole process of copying is invisible to the user and does not distract him from his work, and the program uses minimum system resources and does not slow down your computer.
Choosing a copy There are three basic types of backup:
full, incremental and differential. Full copies in full copying the data is copied entirely whether or not the files are updated in between copying. incremental backup incremental backup involves copying only those files that have changed since the last backup session, as well as new files. Files that remain unchanged are not copied. differential backup differential backup is understood under the copies of all the information changed since the first backup session. A differential backup is different from incremental in that the data is copied, changed since the first session of the copy and not the latter. Choosing a software helps you find the most suitable ratio between the speed of copying and saving storage space for backup. Backup with timestamps Another advantage of the program backup is that it allows you to save multiple versions of the same file with timestamps, so that the user has been able to recover any file in the form in which it was at a certain time. The user specifies the number of copies of the same file to save.

Compression and Encryption In addition, a professional backup software allows automatic data into the archive to save space, and also has the ability to encrypt data to prevent unauthorized access. recording to more one definite advantage backup software is that it can record the backup data to any media. That is, in its functional program has tools burning optical discs such as CD, DVD, HD DVD, Blu-Ray. Also the program can write backup data to network drives, FTP servers, removable media, etc.
Together these features allow you to completely automate the process of backing up data on your computer, so that no one byte of information was not lost! Summarizing, we can say that the backup software - is the most optimal solution to protect data from loss. Of course, one may consider the purchase of a luxury of such a program, but do not forget that the loss of valuable information you can turn into an even greater luxury, both in monetary and emotional terms.
