I hope someone can help, I have been working on this for two days with no luck. The OS user which runs the database is the same user I start Xtrabackup as. The OS user has complete ownership of the MySQL directory, the Xtrabackup directory and my backup destination directory. When I start Xtrabackup it fails with the error below. Any ideas.

try this: cd /opt/mysql/database\_backup touch test and see whether you can create the file. ---

Yup I can create the file. In fact I created xtrabackup\_checkpoints & xtrabackup\_logfile files manually and tried to run the following command and received the below error. innobackupex --user=root–password=password–defaults file=/opt/mysql/mysqldb/db/db.cnf /opt/mysql/database\_backup --no-lock --apply-log – ibbackup=xtrabackup\_55 xtrabackup\_55 version 2.0.5 for Percona Server 5.5.16 Linux (x86\_64) (revision id: undefined) xtrabackup: cd to /opt/mysql/database\_backup xtrabackup: error: xtrabackup\_read\_metadata() xtrabackup: This target seems not to have correct metadata… InnoDB: Error: tried to read 2048 bytes at offset 0 0.
