I tried to backup my currently running mysql server using the following command:
innobackupex --user=root --password=password /root/percona-backup/
It failed with the following error:
xtrabackup: using O_DIRECT 2014-02-16 03:49:05 7fec9403c720 InnoDB: Operating system error number 2 in a file operation. InnoDB: The error means the system cannot find the path specified. InnoDB: File ./ib_logfile0: 'open' returned OS error 71. Cannot continue operation innobackupex: Error: The xtrabackup child process has died at /usr/bin/innobackupex line 2642.
Could anyone please help me with this error?
