I’d like to get some advice and pointers from fellow users of percona xtradb and xtrabackup. I am working on backing up a fairly busy database server(4.8TB) to an NFS export hosted on a NAS4Free server. I am not allowed to take it offline during the backup. Other than making sure to mount the NFS share with noac,noasync are there other things I should watch out for? (from percona post:[URL=“[http://www.mysqlperformanceblog.com/2010/12/09/using-xtrabackup-on-nfs-for-mysql-backups/](http://www.mysqlperformanceblog.com/2010/12/09/using-xtrabackup-on-nfs-for-mysql-backups/)”][http://www.mysqlperformanceblog.com/...mysql-backups/[/URL]](http://www.mysqlperformanceblog.com/...mysql-backups/%5B/URL%5D)) Also, should I use xtrabackup or innobackupex? Am I correct in my understanding that xtrabackup is used to backup a database with purely innodb tables? In my case, the main database(4.5TB) is all innodb but the other databases like mysql contain myisam tables. So in my case, I should use innobackupex to backup all databases?
