It is possible to restore a deleted MySQL database
Yes, undeleting a MySQL database is possible, although it is not very easy. Even if you are a conscientious user and constantly make backups, you may have problems with restoring databases.
A database could be damaged or deleted immediately after a backup. But it would be very unlikely. Usually, a backup makes it possible to return only part of the data, and the rest is completely lost. And the amount of information lost will depend on the downtime. Therefore, you definitely need to hurry to restore a deleted MySQL database and prevent losses.
The first step to recover deleted data from a MySQL database
Despite the fact that backing up doesn’t save much, it’s worth starting MySQL recovery as soon as possible. After all, this is the simplest and most free method, and not using it would be stupid.
To prevent any data from being damaged, first, place it on a new server. Here you can safely view the desired rows, columns, etc. You can see that the backup will have what you need, then take and copy this information to the old server. This way, you secure your existing database and at the same time return the missing information.
If you did not succeed in retrieving information in this simple way, then you will have to resort to the next method.
