Storing your data locally can impose security and availability risks. Major cloud providers have object storage services available to allow you to upload and distribute data across different regions using various retention and restore policies.

Percona XtraBackup delivers the xbcloud binary – an auxiliary tool to allow users to upload backups to different cloud providers directly.

Today we are glad to announce the introduction of the Exponential Backoff feature to xbcloud.

In short, this new feature will allow your backup upload/download to work better with unstable network connections by retrying each chunk and adding an exponential wait time in between retries, increasing the chances of completion in case of an unstable connection or network glitch.

This new functionality is available on today’s release of Percona …

Problem Statement

Having backups of binary logs is fairly normal these days. The more recent binary logs are copied offsite, the better RPO (Recovery Point Objective) can be achieved. I was asked multiple times recently if something could be done to “stream” the binary logs to S3 as close to real-time as possible. Unfortunately, there is no readily available solution that would do that. Here, I show what can be done and also show a proof of concept implementation, which is not suitable for production use.

In this example, the instance has two binary log files (mysql-bin.000001 and mysql-bin.000002) already closed and mysql-bin.000003 being written. A trivial solution for backing up these binary log files would be to back up just the closed ones (the one that is not written). The default size of the binary log file is 1 GB. This means with this solution we would have a 1 GB binlog not backed up in the worst-case scenario. On …
