Is it possible to manually restore a database created from an "Entire MySQL Directory" backup option?

Question

When using the cPanel Backup Feature, you can backup the entire MySQL data directory using the following option.

WHM: Home -> Backup -> Backup Configuration

This will create a full directory backup of the MySQL directory in your backup directory.

Example: 

/backup/2020-08-13/system/dirs/_var_lib_mysql_.tar.gz

Once expanded, you will find the 'raw' MySQL database directories and files.

Example:

# tar -ztvf _var_lib_mysql_.tar.gz  | grep cptest
drwxr-x--- mysql/mysql        0 2020-08-13 08:36 var/lib/mysql/cptest_cptest/
-rw-r----- mysql/mysql       65 2020-08-13 08:36 var/lib/mysql/cptest_cptest/db.opt
drwxr-x--- mysql/mysql        0 2020-08-13 08:38 var/lib/mysql/cptest3_cptest/
-rw-r----- mysql/mysql       65 2020-08-13 08:38 var/lib/mysql/cptest3_cptest/db.opt
drwxr-x--- mysql/mysql        0 2020-08-13 08:38 var/lib/mysql/cptest4_cptest/
-rw-r----- mysql/mysql       65 2020-08-13 08:38 var/lib/mysql/cptest4_cptest/db.opt

Question: Is it possible to manually restore a database created from an "Entire MySQL Directory" backup?

Answer

Yes. 

The process of manual database restoration is a task that is best handled by a database administrator with the skills, training, and expertise required to do so for you. cPanel does not have a Feature for this kind of database administration task. The process of restoring a database from raw/physical files is complex and has a large potential for risking irrecoverable data loss.

We strongly urge you to complete a MySQL backup before attempting this type of restoration.
