Problem: ======= mariadb-backup creates one background thread to copy innodb redo log. It does copy all the data file (in main thread and other concurrent threads), till it explicitly mentions the redo log thread to exit. This redo log copier thread run keep printing the current states of redo log copied lsn for every 15 seconds. If BACKUP STAGE command takes time to finish or any stall during data copy then redo log background continuously emitting the same log copy status gives the impression that redo log is being stuck Solution: ========= backup_log_report(): Reports the log progress report information for backup only when InnoDB does have any redo log to copy xtrabackup_copy_logfile(): Print the redo log progress information after coping the new redo log. |
