After changing the transactions in my app, my innodb binlog is increasing fast than before change.
Now I have getting error in my backups and it never ends. Before backup take about 3,5 hours or so and now after 7 hours it has taken about 25% of total backup size.
I have tried with version 1.6.4 and 2.0.2 and the error is:
###Warning###: The copying transaction log migh be overtaken already by the target.
: Waiting log block no 80669053, but the bumber is already 84765037.
: If the number equals 80669053 + n * 2047992, it should be overtaken already
xtrabackup: error: log block numbers mismatch:
xtrabackup: error: expected log block no. 410098410, but got no. 412146402 from the log file.
xtrabackup: error: it looks like InnoDB log has wrapped around before xtrabackup could process all records due to either log copying being too slow, or log files being too small.
xtrabackup: Error: xtrabackup_copy_logfile() failed.
Why is it running so slow ?
