Not respecting NULLs and Restore always fails exceeding memory

[DPineault]

I have made several backups with this extension, and they seemed to work.

Today I needed to perform a restore and I can't. It always errs giving memory errors. I've pushed the memory allocation to 4GB and still can't handle the restore?!

Then I decided to take the sql file and simply import it. 4 hrs to process in PHPMyAdmin and it didn't work. Using the mysql command line I get back errors relating to the fact that it seems to have converted all the NULLs to 0 or '' making the backup useless.

Hopefully you can address these issues, give some ability to configure certain settings, but for now this extension is not ready for real-world use.
