Magento: 500 internal server error :: Back-end >> System >> Tools >> Backups

Question

We are unable to create magento backups from “ Back-end >> System >> Tools >> Backups” menu on magento version 1.5. When we are trying to create a backup after 15 to 20 mints system return a error message:

---

Internal Server Error 
The server encountered an internal error or misconfiguration and was unable
to complete your request.

Please contact the server administrator, [email protected] and     
inform them of the time the error
occurred, and anything you might have done that may have caused the
error.

More information about this error may be available in the server error
log.

Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

We have applied almost every solution which we found on magento forum, since a lot of people faced that issue previously. The solutions which we have applied are:

• Change permissions to 777 on “var” folder.
• Made “var/backups” folder empty.
• Changed permissions of ROOT index.php file to 755.
• Increased the MAX TIME of execution in PHP.
• Increased the Memory limit.
• Replaced index.php file with the index.php.sample for temporary bases.
• Enabled the “Log Settings” to see what error system is generating. Check the attached “system.log” to see any error related to maganto backups?
• Replaced “split” with “explode” php function in the file “app/code/local/MageWorx/LinkExchange/Controller/Router.php”

But, no luck found we are really unclear what is wrong. We are planning to upgrade the magento version from 1.5 to 1.7 and we cannot start that process b/c we are unable to complete the backup process.

The worst part is when system returns the error message “500 internal server error” , then we reload the Dashboard page of back-end and it shows us message in green color that your “backup process has been completed”, it also shows the list of backups which system has created. But, we are sure that is not a complete backup OR should we assume that the backup has been completed?

The above errors we got from “system.log” file there are errors on “Router.php” and “Navigation.php” is that something wrong with URL rewriting? As per our understanding “500 internal server error” also returns if routing is not correct.

Can anybody let us know and help us out what is going wrong since we have tried almost everything. Also, please check the attached “system.log” file may be someone can find a clue what is wrong with backup system of magento.

Answer 1

First of all, measuring the exact time would be very helpful at determining where the problem is, getting it it within a min could lead to an exact timeout.

Could be wait_timeout in MySQL's configuration /etc/my.cnf

Secondly, there is nothing magical about the backup process. It sounds like you have a working knowledge and access to your server. You can use zip to zip up the whole magento web root, and use mysqldump to get a copy of database. That is all that you really need to rebuild a PHP/MySQL application.

Also, it almost sounds like you are planning on trying to upgrade Magento 1.5->1.7 on a live production server. This is almost certainly a mistake, numerous features will change and extensions may or may not play nicely with the new version. I highly suggest doing the backup as described above, and deploying to some sort of a testing environment where you can do the upgrade and take notes on what problems occur.

Answer 2

To find out what the error is, you can uncomment the line

ini_set('display_errors', 1);

The line is located in the index.php file.

Then you will see what exactly triggers the above mentioned error.
