SQL backup/restore 64 to 32bit.

    Hi folks,

    I have a problem with a MySQL database trying to backup a from a 64 bit OS and restore to a 32bit.
    When I backup using MySQL Administrator on the 64 bit OS it all goes like clockwork but when I copy the file to my 32bit OS and attempt a restore it fails miserably.
    When I analyze the file it seems fine and it restores fine on the 64bit.

    I've googled this on numerous occasions but no luck. Anyone know if I need to have some sort of converter for this or any advice on what i'm doing wrong?

    Ta.

    What kind of restore are you doing? Is it just from standard text .sql files, or is it some other form of backup?

    Does the MySQL administrator give any actual errors or just say "failed"? I would try to use some other GUI (or the command line client) to do a restore to a dummy database, and see what errors pop out.

    Taking an extremely blind guess here, I'm going to say that MySQL is 64-bit aware and created the tables using some form of engine which is only available/only works with a 64-bit OS. So when you're running the backup onto the 32-bit install, it's trying to create a table using an incompatible/unavailable engine type.

    Should be simple enough to fix - Search/Replace using a text editor.
