Try taking backup using "Cloudbacko software" i have experience of using CloudBacko software for my MYSQL database backup. Currently, i am using the same software because it gives me full security and protection to my data. Backup of a large 100GB MySQL Database can be finished overnight. Fast multi-thread MySQL Database backup. Block level incremental hot backup with zero downtime. MySQL Database backup pre-requisites checking guarantees restorability. Multi-destination concurrent backup. Directly restore from backup to original database. Service is very good so i would like to suggest you to have CloudBacko software for your backup plan.
