Corruption in mariadb binlog












1















I have an installation with mariadb version 10.0.21.



I need to backup the binlog file every 5 minutes to TSM, but as the binlog is being written every second, i am afraid of the file getting corrupted when copied.
Is it possible that this happens?
If the binlog gets corrupted (the end of it), will it corrupt the entire file or i can discard the last lines?
Any other solution proposed? We already have replication with master/slave, but for security and audit reasons, we need to keep a copy of the binlog.



Regards

          • Percona xtrabackup does not allow binlog backups, is just for db backups. Or maybe i am not looking well enough, do you have any guide for that?
