Four tips for backing up the operating system Active Directory

Backup is important. Without a backup, you cannot recover lost or corrupted files. You should always back up and test the effect. Without testing (restoring files from backup media), it is not possible to know if the backup method is feasible. Every important file in the network should be protected by backup, including the Active Directory domain controller. Just imagine, because a sudden blackout damages all drives of a domain controller, causing you to lose the results of years of work, including the entire design of the corporate network and its structure. Due to the expansion of the network and your company's reliance on the network, it is necessary to have a reliable backup. Desktop backup programs are not suitable for servers, let alone ad domain controllers. The backup method you choose should have sufficient ability to recover data files and Active Directory databases. When choosing a software backup method and the hardware devices you use, consider the following:

Server Mirroring

A real-time backup in which identical data can be created on the backup hardware. It can be done through the RAID1 system or with a full mirror server hardware device. This real-time backup is usually done locally. When the primary system is compromised, you can quickly failover through mirroring, using the backup device.

Electronic links

The backup method is to periodically transfer the changed files offsite. Also known as batch processing. This offsite backup is not real-time and provides a more appropriate way for you to recover ad networks when the primary system is severely compromised.

Remote Log

This real-time offsite backup delivers incremental (changed elements) rather than the entire change of the file. It is a very reliable way to recover ad networks when the primary system is severely compromised.

Database image

The combination of server mirroring and remote logging can create multiple local and offsite backups. This real-time backup can be local or offsite. This method is the most expensive, but when the domain controller is affected by any impact, it is the best choice to recover ad.

Whichever method you choose, you must ensure that your backup media, including tape, fiber, and hard disk drives, have sufficient capacity to meet current and short-term needs. The size of the ad database increases every week, so plan ahead to take full advantage of the storage space in the backup medium. It is also necessary to ensure that the main data resource and the connection line in the backup medium are sufficient to support the transfer of backup data. Real-time backup requires sufficient bandwidth to ensure 100% feasibility and uptime, allowing for the transmission of real-time change information. Backups can sometimes interfere with the capacity of the network. This requires the deployment of a second network with functionality, especially on a 24x7 network with high-level ad interactions.
