Backups lose your data, the only question is when. Everyone who uses computers and other devices to store information known about the inevitability experience a crash from time to time. Sometimes data are overwritten by mistake; sometimes the discs break or equipment is damaged (as a flood or blow). The best protection is to arrange a routine backups (backups) to ensure that we will not lose anything too important. Nowadays almost all computers are synchronized with each other and often have copies of the information in several places. Another idea is to use system utilities to schedule the task in a reasonable way: for example, a full backup each month, plus a copy of the changes every week or even every day, depending on how it is used. Important: better on an external drive that, if not soon will. In addition, who is conscious, you just get one disc to another place other than your home or office.
