Hello,
I’m running a MySQL 8.0.28, which has a master and a slave, and the Xtrabackup v. 8.0.35-30. The backups are being performed on the slave. The problem is that while the backup is being made, the replication seems to stop, causing a high value for seconds behind master. I have others environments with the same versions, running the exact same backup script and this behavior does not occur on them.
How can I identify what is causing this behavior?
