Create Backup Set

Backup Requirements

Please ensure that the following requirements are met by the MariaDB server.

1. MariaDB server is installed on this computer.
2. The MariaDB database instance is online.
3. The MariaDB database instance listening port is 3306. Check using the netstat -an command.
   

   For example:

   Active Connections
   Proto   Local Address    Foreign Address   State
   
   TCP    0.0.0.0:3306     0.0.0.0:0       LISTENING
4. The mysqldump utility is installed on the MariaDB database server.
5. The mysqldump utility is the same version as the MariaDB database. To check the mysqldump version use the mysqldump --version command.
6. A MariaDB user with ALL PRIVILEGES must be prepared for the backup operation.

   For example:

   MariaDB [(none)]> GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost' IDENTIFIED BY 'password';
   MariaDB [(none)]> GRANT ALL PRIVILEGES ON *.* TO 'username'@'localhost.localdomain' IDENTIFIED BY 'password';
   MariaDB [(none)]> FLUSH PRIVILEGES;
   
7. Verify that 'localhost' on the MariaDB database server is resolvable and 'localhost' is allowed to access the MariaDB database instance on the MariaDB service listening port.
8. The 'information_schema' and 'performance_schema' databases are MariaDB virtual system databases, which contains information about the user databases on the MariaDB instance are automatically excluded from the backup source. They are read-only and cannot be backed up.
9. Databases selected for backup will be temporarily spooled to a temporary directory before being uploaded to the backup server or destination storage.
   Please ensure that the temporary directory configured for MariaDB database backup:
   • is not located on the Windows System C:\ drive
   • has sufficient disk space for the backup operation, the free space on the temporary directory drive should be at least 150% of the database size. As the temporary directory is also used for storing index files and any incremental or differential delta files generated during the backup job before they are uploaded to the backup destination.
     For example:
     If the default setting for Delta ratio is 50% for in-file delta, if the total MariaDB database size is 100GB and there is only one backup destination, the minimum free space needed on the drive where the temporary directory folder is located = 150GB
     100GB = Total MariaDB database size
     50GB = Total maximum size of incremental or differential delta files generated
     
   Please bear in mind the size of the databases may grow over time and you may need to review the temporary directory free space requirements on a regular basis.
