The backup It is a duplicate made of the user's most important information, such as personal data, important documents, etc. It serves to securely store all files, without the risk of losing them if they are lost from the original device's storage.
The Backup or backup It allows us to keep our most important files safe in case of document loss, cyberattacks, computer viruses, household accidents, etc.
Thanks to the backup, The user can browse more safely and calmly, knowing that all their essential documents have a duplicate, which will allow them to easily recover them in case they lose the original file.
The backup It's not focused on saving all the files you store on your computer, but it's designed to do backups of those documents and files that are most important and unmissable for you.
The approximate frequency with which you should perform these backups depends on the amount of information you move on the computer. In other words, if you have a high rate of file exchange, you should make these backups more frequently than if you have few important files and don't move them around much.
The backups They can be stored on secondary drives, our own computer, external hard drives, USB flash drives, pen drives, CDs, etc. What we must keep in mind is that if we decide to do the backup It is advisable to perform a second one on our own computer. backup on an external device, so as not to risk losing the files.
Although data recovery programs do exist, they are not completely effective and may not solve the problem, causing the user to lose all their most important files and documents.
It is important that while we do the backups Make sure there are no open documents or files running, as you might be copying files that are currently running or open, and there's a risk of the copy not being successful. This often happens with databases, so it's important that all files are closed and that you're not working on them at that moment.
In order to optimize the copying and storage processes of the backup, various data manipulations are performed.
- Compression; The best method to decrease the storage space required and also reduce the cost.
- Redundancy; When multiple systems store their backups Within the same storage system, there is the possibility of redundancy in the copied data.
- Deduplication; When the backups They are duplicated on a second storage device. Deduplication helps optimize speeds, provide a safe second copy, etc.
- Encryption; the limited capacity of storage media means there is a high risk of loss or theft. Encrypting information can mitigate this problem, although it has the drawback of consuming a lot of CPU time and potentially slowing down copying speeds. Furthermore, compression becomes less effective once data is encrypted.
