Back up an ApsaraDB RDS for MariaDB instance - ApsaraDB RDS

You cannot manually back up your ApsaraDB RDS for MariaDB instance. You can configure a backup policy that allows ApsaraDB RDS to automatically back up the RDS instance.

Usage notes

Backup files occupy backup storage. Each RDS instance is allocated a free quota on backup storage. If the amount of backup storage that you use exceeds the free quota, you are charged for the excess backup storage that you use. We recommend that you specify a backup cycle based on your business requirements to maximize the usage of the free quota. For more information about the free quota on backup storage, see View the free quota for backup storage of an ApsaraDB RDS for MariaDB instance.
We recommend that you familiarize yourself with the billing methods and billable items. For more information, see Billable items, billing methods, and pricing.
For more information about the billing rules of the backup storage usage, see ApsaraDB RDS pricing.
Do not execute DDL statements during a backup operation. If DDL statements are executed during a backup operation, the relevant tables are locked and the backup operation fails.
We recommend that you back up your RDS instance during off-peak hours.
If your RDS instance has a large amount of data, a backup may require a long period of time to complete.
Backup files are retained for a specified period of time. Before the specified retention period elapses, we recommend that you download the backup files to your computer.

Backup description


Database engine	Data backup	Log backup
MariaDB	Snapshot backup is supported. Physical backup and logical backup are not supported.	Log files occupy the storage capacity of the RDS instance. If the size of a log file exceeds 500 MB or the period of time during which log data is being written to a log file exceeds 6 hours, a new log file is generated. The original log file is asynchronously uploaded. You can use the Upload Binlogs feature to upload log files to an Object Storage Service (OSS) bucket. This does not affect the data restoration of the RDS instance, and log files no longer occupy the storage capacity of the RDS instance. Note The OSS bucket in which the log files are stored is inaccessible.
