What is a backup/backup? What is a backup for? What are the types of backups? Let's start by defining the backup in a simple way. It is a backup or a backup you make to your files, some decide to make backup copies of their chats, photos, videos, WhatsApp documents.
What is a backup for?
Of course, like many other people, you have important information stored on your PC that you can lose due to an electrical failure and the information has not been recorded, or that the disk on which it is stored is damaged, or a virus or hacker is attacking the your data, you can definitely lose it.
You can run the backup or backup on an external hard drive. These discs are currently storing information with impressive capacity. That is why they are an option to have data always at hand quickly and easily; However, it could happen that a drop occurs and the information is lost because the damage is irreparable.
Or they can be performed in backup automatic, for this there are many software that you can program so that from time to time it automatically stores a certain amount of information for you. We already know why data backup is so important and you can perform a program-free backup or backup to avoid the loss of your valuable personal information.
There are many types of information backups and they can be full or full, differential, mirror, here we will explain the top 5, but there are also synthetic full, reverse incremental, continuous data protection or CDP backups, among others.
Full or complete backup
As some industry experts call it, and literally all the files you have come copy, doing this may take a long time or require a lot of resources on the network or computer; because we are moving large amounts of data, so it's not good to do it that often.
Differentials, backup the files you use most
To illustrate, imagine you have 100 files and want to perform an incremental backup for the first time; Then once the full backup is done, only the files you made changes will be chosen, let's say you only did it with 50, so it will only take those, you can download a program of backup to choose the modified files.
Backup mirror a cosa serve?
It is an exact copy of what it comes from backed up, regardless of whether there are changes or not, or whether a file has been deleted or not. As we said at the beginning, these data backups can be made to hard drives or hard drives, to have them locally.
But when a lot of information is already managed, the backup is kept externally, this is done for protect your data from fires, robberies, some natural disasters or external situations that cannot be managed.
Currently the most common backup of information is i backup online, this storage medium is always connected to the Internet, it is a cloud storage service for backup, where they use a server to protect important documents.
We have seen what that means backup and that there are many ways to do it. And in many cases it is possible to combine more than one option to get the best result. Some people find it appropriate to do a daily backup and then a weekly differential, combined with a full one.
Keep in mind that the space you have is a factor that affects the decision of which method you will use to perform the backup. If you only use your computer for personal things, no problem, you can save your photos or videos on social media without publishing them, have them as a private backup.
Now you just have to evaluate your options because you already know what a backup is and what it is for, or how we learned a backup, plus all kinds of information backups that are available for your convenience.
