xtrabackup incremental backups

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
