Remote Backup using innobackupex

Please pardon me if this is a stupid question - I’m very new to Percona.
I need to perform a backup of a database from a central server.

I thought the command to use was:

innobackupex-1.5.1 --user=root --password=xxxxxx --host=dtcs-clalcpm01-mgt /data/percona_backups

This seems to connect to the remote database server but it still attempts to backup a local instance of the database.

J_Grieb,

XtraBackup has to be run from the server where MySQL is running because it will need to copy the files. You can create a wrapper script for the innobackupex command to be called remotely instead.

Since innobackup just run in local machine, why innobackup has option ‘–host’?
