Restore not Working


i try to restore from a backup from saturday, i allready prepared the backup via:

innobackupex --use-memory=16G --apply-log /mnt/mysqlbackup/2014-10-11_18-05-35/ 

and then i used copy-back:

innobackupex --copy-back /mnt/mysqlbackup/2014-10-11_18-05-35 

But it will stop with this error:

prints "completed OK!".

innobackupex: Error: Original InnoDB data directory '/var/lib/mysql/idbdata/' does not exist! at /usr/bin/innobackupex line 2141.

my Datadir is set to datadir=/var/lib/mysql in the config but i also have the innodb_data_home_dir set to /var/lib/mysql/idbdata/

So something is messed up here. Because if i create the innodb_data_home and try to restore i get an error that /var/lib/mysql/ is not empty.

innobackupex: Error: Original data directory '/var/lib/mysql' is not empty! at /usr/bin/innobackupex line 2162.

How can i get my database restored now?

thanks in advance.

You can try changing your innodb_data_home_dir outside of /var/lib/mysql temporarily while you do the restore. You can always move this back into /var/lib/mysql after innobackupex has finished.
