At the current moment XtraBackup has limited support against partitioned tables:
1. If xtrabackup is being used for backuping database, containing partitioned table - all .ibd files are backuped, but <tablename>.par file is not.
2. If innobackuex is being used with --tables-file option (and the table list contains partitioned table) - only *.par files are being backuped.
3. xtrabackup should support backups of tables with composite partitioning when partitions are kept on separate storage devices.
