Description
Hi,
I noticed that servers running hourly backups rotate the binary log every hour at backup time. Upon further investigating it turns out that mariabackup causes this when --galera-info is enabled and GTID replication is enabled: https://dba.stackexchange.com/questions/331393/mariabackup-flush-and-delete-bin-log
This is undocumented behaviour so I don't know why mariabackup does this. Reading the code (https://github.com/MariaDB/server/blob/cbabb95915d55ce7004f4b7e103aa1143549d384/extra/mariabackup/backup_mysql.cc#L1447) sheds no light on the reason.
If it is not necesarry I would like to be able to control if this is executed or not. If it is necesarry I think it should be documented.
Thank you,
Michael
