We wanted to optimize and test backups for one of our new large scale setup before we could finalize on the backup plan. Our challenge was the data volume was almost 30x more than our normal volumes. Since this involved large volume of data we thought this might be a good candidate to test incremental backups. We wrote a wrapper script to save the states between full backups and incremental backups and did some tests with smaller data sets. It worked perfectly fine. The version of xtrabackup we were testing was 1.6.2.

The incremental backups were completing well within 30minutes. We set out to test what would happen if the amount of incremental diff was large. While doing this test, we started getting backup failures with the following error

Backups are an integral and very important part of any system. Backups allow you to recover your data and be up and running again, in the advent of problems such as system crashes, hardware failures or users deleting data by mistake. I had been evaluating backup solution for a while but to be honest I really wasn't satisfied with the solutions available until I came across XtraBackup and I am loving it since. In this post I intend on showing how to do backups and restores using XtraBackup.
