# 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 #
