Pmm mysql backup


[Detailed description of the issue or question]

Mysql binary log increases when performing Mysql full backup using PMM.
As far as I know, mysql binary log is created when mysql is restarted,
When I checked with systemctl status mysql, mysql was not restarted.
I wonder why mysql binary log is newly created every time I do a full backup with PMM

thank you

Hi @ pmmChobo,
Xtrabackup does not copy all binlogs, it copies only the last binlog file. To copy a smaller last binlog FLUSH NO_WRITE_TO_BINLOG BINARY LOGS is executed as part of the backup, this is why a new binlog is being created.

I hope I could answer your question,
