Database Backup offers the full backup, incremental backup, and data recovery features to meet the needs of different scenarios.

Real-time backup with minimal RPO

The database is the most valuable asset of a company, which means it is essential to maintain database backups. DBS allows you to perform database backups weekly, daily, or hourly, based on the importance of your data. When a fault occurs with your database, you may lose periods of critical data if you perform weekly, daily, or hourly backups. This is unacceptable for game and financial companies.

To minimize the data loss when faults occur, DBS offers real-time backup, which allows you to restore your database to a precise point in time.

Table recovery

Full backup is the most common data backup solution. If you have mistakenly deleted a table in your database, you need to restore the whole database to find the deleted table. This traditional solution is time-consuming and leads to a prolonged failure recovery time.

To quickly recover from database failures, DBS allows you to restore individual tables to meet your specific needs.

Long-term data archiving

Long-term data storage is often needed to meet compliance requirements. The traditional solution is to store data on disks or magnetic tapes. However, when a hardware failure occurs, the reliability of the backup may not be assured. If data recovery fails while performing a critical task and you do not have a backup, you will lose all of your data. As the amount of data to be backed up increases, data management will also become more challenging.

DBS provides a complete lifecycle management solution for data backups. You can select different storage types based on the frequency of data access. DBS automatically transfers backup sets to different storage locations and deletes expired backups based on your settings.

Cold backup sites

A complete database disaster recovery solution requires local database backups, and backups in remote locations. In traditional solutions, backup sets are saved in redundant disks or servers, which can be easily damaged in the event of natural disasters, such as earthquakes or typhoons. To store backups in remote locations, you first need to build multiple backup sites in different regions. This requires very large investments.

DBS offers the Pay-As-You-Go billing method, and supports RDS instances and databases deployed in on-premise data centers, ECS instances, and third-party cloud environments. DBS keeps your database backups in Alibaba Cloud OSS.

Apart from cold backup sites, you can also use DTS to build hot backup sites. When a fault occurs at the business center, all traffic to your service is directed to the local data center or backup site.


  • Cold backup site: Requires relatively low costs. Stores data in Alibaba Cloud OSS. The data recovery time is within several hours.
  • Hot backup site: Requires high costs. Stores data in databases. The data recovery time is within several minutes.
