When you migrate to Amazon RDS using a physical backup, it can be much faster than using a logical backup - but it’s not the right option for every use case. If your dataset is larger, you will see even more of a difference. The XtraBackup method was about 60% faster than mysqldump. Some part of that is the normal overhead of creating an RDS instance, which always takes a few minutes.Īlthough my test dataset was small (13.5 GB) compared to most production databases, it was large enough to show a significant difference between physical (Percona XtraBackup) and logical (mysqldump) backups. The mysqldump backup took 22.5 minutes to restore, and Amazon took 10 minutes and 50 seconds to create the RDS instance from the backup. Add the time to copy the backup to S3 (37 seconds), and the two methods are almost identical. Time Comparison The time to back up was close: 8 minutes for Percona XtraBackup, and 7.5 minutes for mysqldump. If the source instance is not in the same VPC as the RDS instance, set up a VPN connection between the two networks in order to protect the replication traffic. I took a backup from the EC2 instance with this command, using gzip to create a compressed backup:Ĭurrently, there is no way to make this connection use SSL. Then I installed the latest percona-xtrabackup-24 (2.3 would also have worked) and the AWS CLI tools. I filled the table with junk data to make the total data size about 13.5 GB. Demonstration – Migrate to Amazon RDS Using Percona Xtrabackupįor this demonstration, I created a Percona Server for MySQL 5.6 instance on EC2 with the sakila sample database and an extra InnoDB table.

If those limitations don’t apply to your use case, read on to learn how to migrate to Amazon RDS using Percona XtraBackup and restoring it into RDS. (You can’t use Percona Xtrabackup’s partial backup feature when migrating to RDS.) You can’t choose which databases and tables to migrate this way - migrate the whole instance.User accounts, functions, and stored procedures are not imported automatically.The total data size is limited to 6 TB.You can’t restore into an existing RDS instance using this method.Earlier and later major versions are not supported at this time. Source and destination databases must be MySQL 5.6.There are many caveats and limitations listed in Amazon’s documentation, but the most important ones are:
