Employee +1 Vote Up -0Vote Down

With MySQL Enterprise Backup(MEB) 3.9.0 we had introduced full instance backup feature for cloning the MySQL server. Now with MEB 3.11.0 we have enhanced the feature by copying all the master-slave setup files like MySQL server binary logs(will be referred as 'binlogs'), binary log index files, relay logs of slave, relay log index files, master info of slave, slave info files.

Partial Binary Log Recovery
Employee +1 Vote Up -0Vote Down

I came across a situation recently where I was asked if it was possible to edit a binary log to remove a part of it to restore onto a slave server. Now the choice of doing something like a hexedit did not seem appealing, and the more experienced might suggest that it is simply a matter of using  mysqlbinlog with the --start-position and/or --stop-position options. However, the problem had arisen that required the binary log to played through the replication process onto the slave based on specific options in MySQL cluster, so using an SQL dump from the binary log was of no use.

Initially this may seem like a daunting task where you will have …
