Backup technologies that are used on the server

Every day it becomes clearer that to provide backup information on the server is the need number one for any business. And it is good that restoring the entire archive of events, documents and programs is real with proper selection of backup methods.

Different methods of backup and storage are used to copy information from digital media. These are backup and data redundancy. They are different, but sometimes they can be applied at the same time.

Data redundancy allows in the event of a failure to recover files immediately after a failure. The principle of operation is that if you lose access to a file, it is replaced with its copy. This helps to avoid downtime in the work of the site or application and allows the server administrator to return the system to its original operating state.

The optimal strategy for ensuring data integrity and uninterrupted operation of user resources is the combination of backup technologies and data redundancy. If a single host fails, the machine will continue to work without failures, since the migration mechanism will work, and thanks to the backup technology all files will be restored from the hard disk.

Automated backup solutions

Special comprehensive backup solutions make the procedure easy and do not require active participation and multi-level configuration from administrators.

BackupPC

The solution is used for both Windows and Linux, installed on a dedicated server or VPS, which acts as a backup server. This server then loads the user files. All necessary packages are installed on a single server, and you only need to configure disk access via the protocol or via SSH. On Smile Server virtual servers, you can deploy BackupPC SSH keys when deploying without using additional software.

Bacula

A versatile and technically sophisticated host backup program based on the client-server model. In it, each backup task is set as a separate job. This approach allows you to perform fine-tuning, connect several clients to the same storage, change copying schemes and expand functions with the help of additional modules.

Duplicity

This is a real alternative to all existing backup tools. The main difference of this software solution is the use of GPG encryption while storing information, which increases the security of data storage. The main advantage when using GPG encryption for backup is that data is not stored as plain text. Only the owner of the encryption key can access them.
