In the recent time we have found that the bin log is getting corrupted, 20% binlog files were having errors, which couldn't even pass the sanity check by mysqlbinlog -u user -p mysql-bin.000021 | head -5.
I am month old to MySQL, Is there a way which can reduce binlog corruption or some parameter which is safe for binlog/replication. What is the best way for replication, Master-Master or Master-Slave? Is there a way to get auto backup weekly or monthly.
