So, I decided to make a database backup from the magento admin panel. But it´s taking too long and there´s no way to know if the backup is actually working or if it got stucked. Is there a way to stop the process without losing data? I can´t access to any other admin panel utility or make any purchase on my store.
Yes Admin backup will take too long. Please check whether you selected maintenance mode while taking backup. If so go-to your root folder, and delete maintenance.flag file.
Sometimes the backup process will be running in the background, to kill that restart your webserver or if you know the pid of the backup process, you can kill that through ssh
In order to take backup from ssh use below command
mysqldump -u dbusername -p dbname > backupname.sql.
It will ask for password after entering this. Please note password is not visible while typing. Otherwise you can use this other version but not recommended.
mysqldump -u dbusername -pPassword dbname > backupname.sql.
You can immediately type password after -p option without any space as it is. I used capital P just for a notation.
Backup time depends on how many products & customers you have.
You can truncate all log data in your database.
Instead of Manual backup , you can take backup at night time by setting scheduled backup
System > Configuration > Advanced > system> Scheduled backup setttings
Also, you can take backup in phpmyadmin by importing the Database.
If you have ssh access, you can take backup by commands.
mysql -uUSER -p -hHOST DB_NAME < db_dump.sql
