Information backupBack It is the sector of a chair that allows to support the back or, in a symbolic sense, that which provides support, shelter or support. A information, meanwhile, is a knowledge or a to know.

The notion of Information backup It refers to guard that is made of certain data. The concept is often used in relation to digital data (which are hosted on the hard drive of a computer or computer), although it can also be linked to the physical document protection.

There are various methods for backing up information. One possibility is to copy the digital data to different physical formats: a DVD, a CD, a pendrive (also know as pen drive), a memory card, etc. The Information protection can also be developed by uploading the information to a online service: in this case, what is done is copying the documents to a server and protecting access to the documents through a password.

In general, information backup is a practice of people with a certain degree of experience and knowledge in the field of computer science; programmers and graphic designers, for example, often have a habit of saving Backups of their work on the computer and on the cloud (A space on a remote computer that can be accessed through various services, many of them free, to obtain more space than our own local disk provides).

It is important to note that backing up information is not as simple as creating more than one copy of our files. First of all, one of the most common data loss problems is hard drive failure; let’s not forget that this half Storage is very delicate and has a relatively short useful life, since it is made up of mechanical parts that wear out much more than flash memory (which uses a technology based on electrical impulses, so it has no moving parts). That said, we must not minimize the importance of choosing a reliable medium to store our most precious documents.

Information backupIn addition to assess the durability of the disc, we should think about creating several versions of each project; this technique, called versioned, is widely used in software development companies, and offers multiple advantages, ranging from the possibility of returning to any point of a project if we want to change direction, to overcoming an eventual physical problem on the disk that affects a version. Backups should therefore complement the practice of creating a new version of our documents every time we make a major change.

The backup of information that is reflected on paper can be carried out by making a photocopy of the same. It is important to note that, for greater security, you can choose to make a physical and digital backup simultaneously: for example, a printed document can be photocopied (to obtain several copies of it) and digitized (through a scanner). Once the information has its digital backup, this new document can be protected through the aforementioned systems: hosting it in a storage service in Internet, copying it into a DVD, etc.

Photocopies and digitization using a scanner are often used to keep invoices and purchase documents that are essential for claims and warranty requestsas the paper may deteriorate, tear, or be lost. In addition, in many cases the ink fades over time, and that is why the commercial stores themselves recommend this mode of information backup for the benefit of their customers.

Backing up your information is important to protect valuable data from a possible virus or of attack by a cybercriminal, if we focus on the information stored in a computer.
