How do i backup mysql database to a remote server?

I tried to backup the database of a remote server using automysqlbackup.

From this platform, I learnt it was not possible without ssh and I need to back it up on a remote machine and then rsync or scp to my local machine, so I am now working with mysqldump.

The size of the database is almost 12GB.

mysqldump -h 192.168.10.209 -u user -ppassword testdb   > dump.sql

I tried backing it up and due to internet issues I have been disconnected twice already., and got this error once:

mysqldump: Couldn't execute 'SELECT /*!40001 SQL_NO_CACHE */ * FROM `helmet`': Lost connection to MySQL server during query (2013)

Is there way to continue from where it got disconnected using msyqldump?

I also read that mysqldump is not good for such a big database backup but I need to test it from here only at this moment.

Are there any options that can be used to make it work smoothly and backup my database?

mysqldump allows you to dump databases that are hosted on a remote machine. Let's see how to do that for a single, multiple and all databases stored on a remote server.

We need to know the MySQL user, password, host and port of the remote database. Let's assume the following values for the examples below:

  • host: 14.212.331.87
  • user: guru_user
  • port: 3306 (MySQL default port)

Replace the values of host, user and port with your details.

# Dump a single remote database

# Dump multiple remote databases

# Dump all remote databases

If you need to create a backup of a remote MySQL database, you can use the mysqldump command. The mysqldump application is known as a client utility and installed alongside MySQL itself.

When executed, mysqldump will create a dump file of the database that includes all the data and the structure of the database in INSERT statements that you can run on your local machine to create a local copy of the remote database.

In this tutorial, I’ll work through a simple example of using mysqldump to create a local copy of a remote database. I’ll be connecting to a remote server running Ubuntu Server via SSH, running the mysqldump command to backup the database to a file, and then downloading that file to my local machine using SCP.

1. Login to the remote server using SSH

First, open a terminal and use SSH to login to the remote server hosting your MySQL database. You will need to enter your remote server username before the server IP address using the @ symbol. After running the command enter your password to login.

2. Use mysqldump to create a backup of your MySQL database

Next, on the remote server, run the mysqldump command to create a backup of your MySQL database. Modify the command below and replace your_mysql_username with your MySQL username, and replace your_database_name with the name of your database. Then run the command.

It may take a few minutes depending on the size of your database. The mysqldump command will export the entire MySQL database and write the contents to a .sql file that you can download. This can then be used to create a new instance of your MySQL database on another server.

mysqldump -u your_mysql_username --password='xxxxxxxxxxx' your_database_name > your_database_name.sql

For the next step you’ll need the full path to the backup file, so enter pwd to obtain your present working directory. For example, mine is /home/matt.

3. Logout of the SSH connection

Logout of the SSH connection to your remote machine and return to the shell on your local machine by entering logout. This will return you to the shell on your local machine.

4. Use SCP to download the SQL backup to your local machine

Finally, on your local machine, we’ll use the SCP or secure copy application to download the MySQL backup file from the server via SSH.

In the command below we’re starting scp and creating an SSH connection for the user matt on the IP address 123.456.789.123.

Once logged in, SCP will look for the file at /home/matt/your_database_name.sql on the remote server and download it to /home/work/backups/your_database_name.sql on the local machine. It will give you a useful progress bar, so you can track how much of the database has been downloaded.

scp :/home/matt/your_database_name.sql /home/work/backups/your_database_name.sql

Creating a local copy of your MySQL database is a good idea for several reasons. Firstly, it keeps your data backed up. Secondly, it allows you to create your own development environment where you can safely run complex MySQL queries against your database without the risk of slowing down your production database.

To create a local development environment for data science projects running on MySQL databases my preferred approach is to run MySQL in a Docker container. This is a great way to create a development environment for data science projects that can be run on a local machine without the need to install a full-blown server.
