MyBase for MySQL supports automatic and manual backups so that you can recover historical data when needed.
Backup features
MyBase provides full (data) backups and incremental (log) backups.
-
Data backup: Backs up data and generates a backup set. You can restore data to the point in time when the backup set was created.
-
Log backup: Also called incremental backup. When log backup is enabled, binary logs are uploaded to create log backups. By combining data backups and log backups, you can recover data to any point in time within a specified time range.
For example, if an instance has a data backup set from 00:00:01 on January 1, 2021, and subsequent log backups are available, you can recover data to any point in time, down to the second, after 00:00:01 on January 1, 2021.
Backup storage location
Data backups and log backups are stored in Alibaba Cloud backup storage. They do not occupy the storage space of the instance.
Backups are stored in the same region as the MyBase instance.
You cannot access the backup storage directly. To download a backup, see Download backups.
Backup costs
Backups for MyBase instances are currently free of charge. You will be notified in advance before any fees are charged.
Impact of backups
-
For High-availability Edition instances, backups run on the secondary instance and do not consume CPU resources or affect the performance of the primary instance.
NoteIn rare cases, if the secondary instance is unavailable, the backup runs on the primary instance.
-
For standalone instances that use a single-node architecture, backups affect instance performance.
