I use MySQL and the GUI for backup / restore. I have two databases, with similar size but with very different time to restore (one with 4 minutes and another with 50 minutes). The database that takes longer has many delete operations. I ask for help to solve this.

 Thank you.

Grato. "

there is no "solution", except to stop the many deletes, eventually.
I presume you know that you shall stop all transactions to the database before you actually start restoring?!

The restoration is done on a PC that is not accessed by users. Thus, the current operations do not interfere in the restore operation.
 I hoped there was something like 'shrink database' of mssql or 'pack' of dbf tables.
 Recreate the tables and move data could improve?

"A restauração é feita em um micro que não é acessado pelos usuários. Assim, as operações correntes não interferem na operação de restore.

Recriar as tabelas e migrar os dados poderia melhorar ? "

how big are the backup files?

I use MySQL Administrator Version 1.2.8., and only the default options for backup and restore.
For a file of 215 mb, the restore time is 6 minutes. And, incredibly, to another file, 180 mb, the time is 1 hour (this is the file with many delete operations).
Thank you for your attention.

Because it is a strange case (unknown even by experts), I decided to uninstall everything ( MySql and GUI ) and make a new clean installation. It worked
Grateful for the attention.
