# This is a reference script for Percona XtraBackup-based state snapshot transfer #
# Dependencies: (depending on configuration) #
# xbcrypt for encryption/decryption. #
# qpress for decompression. Download from http://www.quicklz.com/qpress-11-linux-x64.tar till #
# https://blueprints.launchpad.net/percona-xtrabackup/+spec/package-qpress is fixed. #
# my_print_defaults to extract values from my.cnf. #
# netcat for transfer. #
# xbstream/tar for streaming. (and xtrabackup ofc) #
# #
# Currently only option in cnf is read specifically for SST #
# [sst] #
# streamfmt=tar|xbstream #
# #
# Default is tar till lp:1193240 is fixed #
# You need to use xbstream for encryption, compression etc., however, #
# lp:1193240 requires you to manually cleanup the directory prior to SST #
# #
