The linux administrator cannot backup a datafile larger than 2GB. If the database file's size is larger then 2GB, the backup operation failed.
I do a same test with mysqldump.exe successfully, so I think that it's a critical bug of the linux administrator.

How to repeat:
Create a new database and insert data more than 2GB. 
Execute a backup operation with the new database.

Thank you for a problem report. Please, check with newer version of MySQL Administrator, 1.1.5.

Are you sure you use the same filesystem for both mysqldump and backup? Please, send the results of df -k and uname -a commands.

I do the tests with administrator and mysqldump in same computer, so it is sure that they use the same filesystem.

I will download the new version of administrator and do the test again.

Please, test with 1.1.5 and inform about the results. I any case, I'll be forced to use the latest version for verification.

The problem i reported is not a duplicate bug. This problem is a bug of linux administrator, but the other is in windows platform. Their source code are different in windows and linux, aren't they?
I do the test with the new version 1.1.5 in linux, the problem exists also.

BTW, the mysqldump could backup the database file more than 2GB successfully in the same environment, so i think that it is a only a bug of linux administrator.

It is really a duplicate of http://bugs.mysql.com/bug.php?id=15616, because this part of code and 32-bit limitations are surely the same.
