A MySQL backup is a copy of a MySQL database that is made for the purpose of data protection. A backup can be used to restore the database to its original state if it is corrupted or to recover data if it is lost.
MySQL provides a number of methods for creating backups. The most basic method is to make a copy of the database files. This can be done using the cp or rsync commands. The mysqlhotcopy utility can also be used to create a backup of a database.
Another method for creating a backup is to create a MySQL dump file. A dump file is a text file that contains a copy of the data in the database. The mysqldump utility can be used to create a dump file.
The most complete method for creating a backup is to use the mysqldump utility with the –all-databases option. This will create a dump file that includes all of the databases on the server.
To restore a MySQL backup, the files or the dump file must be restored to a MySQL server. The files can be restored by copying them to the server or by using the mysql command to import the dump file. The dump file can be imported using the mysql command or the mysqlbinlog utility.

If a database is accidentally deleted, the first step is to stop using the server and contact Microsoft support. Microsoft may be able to provide a solution that does not require restoring the deleted database.
If the deleted database is older than the last full backup, the best option may be to restore the last full backup and then restore all the differential backups since the full backup.
If the deleted database is newer than the last full backup, the best option may be to restore the last full backup and all the differential backups since the full backup.
If the deleted database is online, the best option may be to use the Restore Database command.
If the deleted database is offline, the best option may be to use the Restore Database command with the WITH MOVE clause.
If the deleted database is a system database, the best option may be to use the Restore System Database command.
If the data files for the deleted database are missing, the best option may be to use the Restore Database command with the WITH MOVE clause.
If the data files for the deleted database are intact, but the database is missing, the best option may be to use the RECOVER command.
If the data files for the deleted database are intact, but the database is corrupt, the best option may be to use the DBCC CHECKDB command.
