What is the proper way to create a backup using the latest xtrabackup (2.0.5) and innobackupex when you have a nonstandard innodb\_log\_file\_size (not 5mb). The command I’m currently running is: innobackupex --user= --password= --defaults-file=/etc/my.cnf myBackup where /etc/my.cnf has the innodb\_log\_file\_size defined to 512MB. Running this command causes the backup process to error saying the log file size is incorrect, not 5mb. Up until this point I’ve hacked in a method that actually reads the passed in defaults file and sets the correct filesize as its defined in there in the script, and this works but I feel like there must be a better way to do this. Thanks! Stephen ---

Hi, Xtrabackup is compatible with any innodb\_log\_file\_size. Can you please attach the error log and the my.cnf? I would like to reproduce the issue. Regards. ---
