All administrators in relation to backups are divided into two groups: those who have not yet set up a system for working with backups and those who already do regular data saving.

Currently, there is always the possibility of some unforeseen factor in a complex modern information system. Today, it can be a careless user action, a hacking attempt, incorrect operation of software updates, an administrator error or a hardware malfunction. And the result of the influence of such factors is the loss of important information that can accumulate for quite a few years.

To reliably prevent the consequences of such unpleasant situations, an information backup system is used.

• data backup
• CDP backup organization

Of course, most modern $1 Web Hosting control panels have special data backup tools. As a rule, a copy can be saved in a separate directory on the hoster's server, copied to your own local computer, or transferred via FTP to another server for long-term storage. However, such tools are not very comfortable to use, they require additional disk space for storing archives. And in the case of using another FTP server, you will need actions for its organization and full support. The main advantage of CDP technology is ease of use. Information is backed up here on a daily basis without any user involvement. To restore the system, the user has access to copies for each of the seven days that have passed, as well as copies for the last two months.

These copies are recovery points. In any of these available recovery points, the user can view all the files, restore or copy any of them. The $1 Hosting has a clear and simple interface. All backup copies of data are stored today on a separate server.

How to back up data using CDP technology

Data backup

A special CDP agent application is enabled on the server that works with the information to be backed up. It runs under the control of another special computer - a CDP server, which stores all backups, and also manages the CDP client.

During the very first access of the CDP server, the CDP agent creates a table where it stores data status information on the hard drive. The entire HDD volume is divided into special logical blocks. Their contents are transferred to the CDP server for storage. The very process of transferring a copy of information is called replication. After the end of the first replication, the CDP agent again monitors the general state of the data blocks. He quickly marks in the table the blocks in which changes have been made since replication. When the CDP server is subsequently accessed, the agent betrays only those blocks that have a mark. Don’t forget about Cheap Reseller Hosting at all.

Backup is much faster

This approach allows you to make backups much faster and save disk space for storing information. Copies of the data are created once a day, and during this time interval, basically, a fairly small amount of data changes. Only the first data replication is stored completely on the CDP server. All other replications contain modified blocks, but in place of blocks without any changes there are special links to all previous replications.
