Magento Large Database Backup/Restore Failed

I have a large database (about 244 MB+) and now I want to transfer it to other location from production to development server for fixing the bugs, upgrading and also backup. The hosting provider is Siteground.com

When I try to ma开发者_JAVA百科ke a backup of magento database using magento backend Backup utility, phpMyAdmin or from Navicat for MySQL, unfortunately it fails each time showing no error.

I need Magento community help. What should I do to accomplish the backup successfully.

Any help would be greatly appreciated!

If it fails by showing a blank screen only then it likely means PHP ran out of time or memory, either way reducing the size of the import would help.

You can often save a lot of space by clearing logs prior to the export. Also, you can export-import some tables separately to spread the work over two operations, phpMyAdmin has a table selection box on the export page.

Use command line MySQL to dump and add an extra flag --single-transaction

mysqldump -hHOSTNAME -uUSERNAME DBNAME --single-transaction -p > myfile.sql

For a 250MB database, you shouldn't have any bother.

As above, flushing Magento log entries will help too, but I can't imagine there is too many in a 250MB DB.
