XtraBackup SST works in two stages: • Stage I on joiner checks if it is SST or IST based on presence of xtrabackup_ist file. • In Stage II it starts the data transfer, if it's SST, it empties the data directory sans few files (galera.cache, sst_in_progress, grastate.dat) and then proceed with the SST or if it's IST, proceeds as before.
