What Are the Differences Between DR and Backup?

Differences between disaster recovery (DR) and backup are as follows:

DR protects data centers against hardware faults or natural disasters, so it requires a safe distance (intra-city or remote) between the production site and disaster recovery site. Backups are used to restore data in the event of unintended actions, virus attacks, or logic errors. Backups are usually stored in the same data center as the service system.
A DR system protects data but focuses more on protecting service continuity. A data backup system only ensures that data generated at different time points can be restored. Normally, a full backup is performed for the first time, which takes a long period of time. Subsequent backups are all incremental backups and can be done quicker.
Disaster recovery can help you achieve an RPO of a few seconds. Backup allows you to set a backup policy to back up at up to 24 time points in one day, so you can restore data to different backup points.
If a disaster occurs, such as earthquakes, fires, or dat center failure, a disaster recovery system takes only minutes to perform a failover, but a backup system takes hours or even dozens of hours to restore the data.
