Check the filesize of MySQL dump ================================

# du -h mysqldump_all_databases.sql 23M mysqldump_all_databases.sql

Backup rsnapshot configuration file first =========================================

############################################################################## # backup_mysql.sh # # by Nathan Rosenquist nathan@rsnapshot.org # http://www.rsnapshot.org/ # # This is a simple shell script to backup a MySQL database with rsnapshot. # # The assumption is that this will be invoked from rsnapshot. Also, since it # will run unattended, the user that runs rsnapshot (probably root) should have # a .my.cnf file in their home directory that contains the password for the # MySQL root user. For example: # # /root/.my.cnf (chmod 0600) # [client] # user = root # password = thepassword # host = localhost # # This script simply needs to dump a file into the current working directory. # rsnapshot handles everything else. ##############################################################################
