The Best Cloud Backup Systems For A Site
Backups: why is it important?
Data backup in the cloud is a fundamental element for any business activity, in fact it allows you to easily manage data and information. Backing up data in the cloud means securing all information contained in the servers of your online business and safeguarding them from any possible malfunctions. Capable of causing complete loss of every single file. In addition to storing data and protecting it from possible server failures, storing information in the cloud also means protecting files from possible external attacks or intrusions by cyber criminals who use malware to get in touch with confidential or sensitive information.
What is Backup?
By backing up a certain amount of information and files in the cloud, we mean the creation of a copy of that particular information, which will then be stored on a secondary site or server in such a way that it is protected from any failure of the primary server or from possible cyber attacks. For the data to be completely safe, for obvious reasons, it is essential that the secondary server is located in a geographically distant place from the primary one. Creating two geographically distant servers, as it is easy to understand, means avoiding malfunctions or group failures, catastrophic events that can damage both the primary and secondary servers at the same time, avoiding criminal actions such as theft, preventing virus attacks or malfunctions caused by errors humans. Therefore, by creating two separate and distant server rooms it will therefore be possible to have two distinct copies of the data and essential files, in such a way that these are protected in any of the previously mentioned eventualities. It is obvious that, for the backup to prove useful, it must be performed as frequently as possible, in this way the secondary server will always be updated with the latest data available.
How backup works
The backup procedure is based on the acquisition of data and files which are synchronized with a secondary server. This allows you to have a certain amount of information stored on multiple servers, so you can recover the data in case the primary storage source gets damaged. In a nutshell, even after a malicious event, it is possible to restore the system and the site to the initial stage by quickly recovering every single file and potentially lost or unrecoverable information. The process of recovering and capturing every single deleted or corrupted file is called file recovery.
What data to save thanks to cloud backup
It is essential to use the backup as a useful means of saving and safeguarding the life of the most interesting and important files contained within your online site. Any company must take advantage of the backup as a means of safeguarding sensitive and non-recoverable information, in this way even in the event of a malfunction of the primary archiving system or even after the theft of a certain amount of files, these will be easily recoverable or reconstructable. The backup system autonomously establishes the frequency with which the data must be rewritten and stored in the secondary archiving system. As we have already mentioned above, the faster data is backed up,
Full backup
There are various cloud backup systems, but one of the most used is the complete one. This cloud backup system is generally considered very reliable because it allows you to rewrite, whenever you want, every single file on the primary storage card, thus reducing the risk of data loss. On the other hand, performing a full backup takes a long time and requires a large amount of space in order to constantly duplicate the entire contents of the primary server. There are several corporate cloud services that allow you to perform a complete cloud backup
Incremental cloud backups
The incremental cloud backup system gives the possibility to make a copy of only every single information modified with respect to the previous save or backup. This particular cloud backup system can run right after a full backup, meaning that future backups focus only on the information that has changed since the previous save. The full backup will therefore constantly update itself whenever the primary save is altered or modified in any way. The main problem or limitation of a cloud backup system of this type lies in the time interval that separates one backup from another, in fact this saving methodology requires an extremely long period of time for its completion,
Differential backup
The differential backup is certainly the most convenient to use by companies, in fact this type of saving technique allows you to save every change made since the last full backup. This particular backup system requires more space, but eliminates the problems that can arise in the case of a backup restore. The only and main disadvantage of the differential backup lies in the increasing and progressive increase of the backup size, which leads to a negative alteration of the saving window.
Synthetic and full backup
The full and synthetic backup system is a system variant of the differential backup. Thanks to this saving technique, a complete copy is generated to which the changes made to the Files are then added, once the original backup has been definitively completed. We therefore have a real combination of the differential and incremental backup process.
