Hello, experts.

I'm trying to build a raw backup and restore strategy for an InnoDB only DB, hosted on a CentOS 6.6 machine with LVM.

Currently, I use a logical backup strategy but restore time is unacceptable since we host databases that can span up to 5 TB of data. The smallest one contains 1.5 TB and takes more than 24 hours to restore. Last time that I've attempted a raw backup I had a mix of MyISAM and InnoDB tables and thought that, that mix did not permit such type of backup.

Apparently, I'm having success with my raw backup strategy, but when I restore in a similar machine and attempt to access any restored table I get the message "Table '<db>.<table>' doesn't exist.".
I've roamed the internet, and the best match that I've found is a StackOverflow question with an answer that points out when using "innodb_file_per_table" we need to copy the ibdata and iblogfiles also.


So, I guess that I need to include some option to backup those files also since when I execute my restore procedure, those files don't have the same size on my destination server. Nevertheless, the StackOverflow question refers that this is needed just to dump the tables with mysqldump, and it isn't a solution to restore data in a production environment.

Can someone help me with the adequate zrm backup and restore options/flags that I need to use to achieve a raw backup and restore strategy with the previously mentioned configuration?

I'm using zrm3.0 and MySQL 5.6 hosted on a CentOS 6.6 (as stated before) machine.

Thanks in advance.
