Is your system backed up correctly?

Is your system backed up correctly

If you suddenly lost part of your database or website, what would be the damage? If such a loss would considerably affect your business, you must be sure that your backups are done correctly. Not every backup copy is a guarantee of security. Only with the correct configuration of the backup system and its monitoring, losses can be avoided.

The loss of information can occur for many reasons:

  • Technical reasons, such as server failure or some other type of hardware malfunction.
  • Loss of information due to the fault of employees who accidentally (or intentionally) performed an incorrect data operation.
  • Harmful activity of partners or other people who have been temporarily given access to the information.
  • Hacker attacks from outside.

The loss of a bigger or smaller part of important data can happen anytime to anyone. If you have configured backups correctly, this will not cause any harm because the system can be quickly restored.

Consider some of the most important points that must be done:

Determine how often you need to make backups

For some systems, to lose the changes made during the current month would not be a problem, because no important changes are done to the data, while for others, changes made every day are significant. It is necessary to determine the optimal frequency for creating backup copies for each specific case, taking into account the cost of placing backups.

Choose where and how the copies will be stored

Backups must be stored separately from the main system physically (on another server) and logically (that is, an attacker, for example, having hacked the site, should not get access to backup copies as well).

Set up automatic monitoring

It is necessary to configure backup monitoring in order to receive an alert if the system for some reason did not complete the backup at the scheduled time. With properly working monitoring, you can always fix an error before it grows into a problem.

Perform recovery testing

It is necessary to regularly test the ability to restore the system from backups. An extremely unpleasant situation arises when, in case of data loss, it suddenly turns out that, despite the presence of backups, it is still impossible to recover the system. Regular recovery test helps to avoid this situation.
