Running innobackupex I see the following in its output:
xtrabackup: error: log block numbers mismatch:
xtrabackup: error: expected log block no. 91292509, but got no. 90768229 from the log file.
xtrabackup: Error: xtrabackup_copy_logfile() failed.
innobackupex continues, but at the end I see this:
innobackupex: xtrabackup_55 failed! (exit code 1) The backup may not be complete.
Studying Bug #805593 I understood that one possible reason for this error message could be transaction log being wrapped around while xtrabackup works.
Will much appretiate if you answer the following:
- Is it really transaction log wrapping issue?
Is there a way to find out?
- If the above is true, how the backup logic should be build?
Shall this go to FAQ/User Guide?
- Is it possible to delay log wrapping till xtrabackup ends?

Thank you and best regards
