I always make backup using "backup and migrate" module. But now, need to automate this process using scripts.

When execute backup using "backup and migrate" this module generate .mysql file with approximately 3.3 MB(compacted) and 9MB(uncompacted) , but using the following script command, file have 17MB(compacted) and 53MB+(uncompacted) and .sql extension.

mysqldump -u user_mysql -pMY_PASS  --databases my_database | gzip > /home/my_user/my_docs/database.sql.gz

How generate ".mysql" extension file using "mysqldump"?

  • Interesting question that I don't think we have here. I'll give time for someone else to answer, but as a side note you can run B&M from drush, and it will be the exact same backup as if you did it from the UI (or cron). – mpdonadio Aug 10 '16 at 20:07
  • Yeah, I have backup / migrate email me backups every day on cron. I think the larger size comes from tables like form cache which can get big. – Niall Murphy Aug 11 '16 at 4:01

    Maybe you are ignoring some tables using BAM as per Niall. That's the reason that I think. With mysqldump you are dumping the whole DB including cache bins. – Gulok Aug 11 '16 at 10:09

My hosting is a non dedicated version, so, I don't install drush. But I found a good solution. In config BAM (/admin/config/system/backup_migrate) have an tab "Schedules". In this option u can add backup schedule. Excellent solution, because winscp script (my script backup hosting) will get .mysql.gz generated in BAM private folder automatically. Additionally, about file size backup, BAM really exclude some data tables. This option is personalizable in "/admin/config/system/backup_migrate/profile/list/edit/default", "DEFAULT DATABASE BACKUP OPTIONS" option "Exclude the data from the following tables".
