Why do two binlog files have similar start and end times?
Both files contain binlogs generated during the backup of the primary and secondary nodes. Each file has a different start time — the files are not consecutive.
Are binlog files compressed?
No. Binlog files are stored without compression.
How are binlog files generated, uploaded, and cleared?
Each stage is triggered independently:
-
Generation: When more than 500 MB of log data is written to a binlog file, ApsaraDB RDS automatically creates a new binlog file.
-
Upload: Binlogs are uploaded to Object Storage Service (OSS) based on local backup settings.
-
Clearing: Local binlog files are cleared after the upload to OSS completes.
