I saw this in another posting…
"You can read to_lsn from xtrabackup_checkpoints and use its value as an argument to --incremental-lsn as described here: http://www.percona.com/doc/percona-xtrabackup/innobackupex/i ncremental_backups_innobackupex.html
Which is easier than recreating the directory structure and copying the entire file."
However this still results in a full backup to the remote host?
#innobackupex --user=xtrabkp --password=***** --no-timestamp --remote-host=remotehost /MysqlBackup/current/base
Incr - when the lsn is derived from the to_lsn in the xtrabackup_checkpoints file in the base dir.
#innobackupex --user=xtrabkp --password=***** --remote-host=remotehost --incremental --incremental-lsn=226576624494 /MysqlBackup/current/
