Now let’s see the different examples of export databases in MariaDB as follows.įirst we need to find out the path of MariaDB server on user machine that means location of bin folder in user machine. It works with milliseconds that means recently accessed data inserted into the new sub list of buffer pool and data which is accessed only ounces should remain in the old sub list of buffer pool.

When we perform a full table scan at that time it copies all data into the buffer pool but this is the disadvantage of logical export because every time it scans the entire table or database and it is a time consuming process, so how we can avoid this problem by using the innidb_old_blocks_time system variable. The buffer contains the frequently accessed data from MariaDB server. When we consider performance then buffer is very important for that purpose. In InnoDB it uses the buffer pool concept to store data and index of its table in the memory. We are also able to dump the data into the other version of MariaDB, MySQL and another DBMS. The mysqldump exports data into the sql format as well as it also exports the data into the other format such as CSV or XML format and it can be easily imported into the other database. If database size is large then it also required large time to table export.
In a logical export database we use mysqldump command, this is more suitable or we can say that more flexible way to perform logical export and it is suitable for small databases. We can perform physical export at the level of directories and files. In physical export we cannot restore data on other hardware configurations like DBMS or different MariaDB versions. The log files and configuration files we cannot consider for logical export. The size of logical export is larger as compared to the physical export and it takes more time to back and restore the database. We can perform logical export at the level of table and database because of flexibility reasons. In logical Export we can restore data on the other hardware configuration such as DBMS or MariaDB version. Let’s see how we can export databases in MariaDB as follows.īasically we can perform backup by using two methods as follows.

How to export database in MariaDB using various ways? This command does not generate any visual output so first we need to verify the generated copy is correct or not. After that we use the specified database name for the name of the database that we need to export and in the last part of syntax contains the data-dump.sql is the file name, it will be generated along with all the database information. In the above syntax we use mysqldump command to export the database here specified user name means user name that refers to the database.
