First, obtain the global read lock, write the data in the cache to the disk, then execute the LVM snapshot, and finally unlock. The following is a main process of my collection.

After the entire process is completed, only backup-20131105_133167_mysql.tar.gz is left. The tar package contains binary log coordinates, my. cnf, and all mysql files.

This tool also has the mail alarm function. The following is the mail alarm section of my configuration file.
# Cat/etc/mylvmbackup. conf | grep mail
Mail_report_on = always
Mail_from = root @ localhost
Mail_to = 645522734@qq.com
Mail_subject = mylvmbackup report for localhost
Note
-- Mail_report_on: Value: {never, always, errors}. never is the default value, always indicates that emails are always sent, and errors is only used when an error occurs.
