The problems you have reported appear to be different from the original one reported in this bug.
In both cases it's probably what the error message says: the 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.
Bernd, Quan,
The problems you have reported appear to be different from the original one reported in this bug.
In both cases it's probably what the error message says: the 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.
Please try increasing the log file size.
