Magento media and system backups fail

[rabakana]

It takes exactly 15 minutes and then nothing happens. From the log I see a lot:

Server admins said that they won't increase any execution time (php/mysql)

@rabakana

Increase your magento excecution time using .htaccess and then try again.

[rabakana]

Thanks for you answer. I changed magento root folder .htaccess from

php_value max_execution_time 36000

to

php_value max_execution_time 360000

logged to backend, tried database and media backup no change - still it calculates 15 minutes and then nothing happens.

[JLHC · Accepted solution]

If you changed the "max_execution_time" in the .htaccess file and it is still not reflected, maybe there are some other configurations which are causing the timeout. 

Anyway I suggest that you consider using an alternative backup solution instead as Magento's built-in backup is not that good anyway due to a few reasons:-

1. It always reset file permissions wrongly to insecure permissions like 666 and 777 after a backup. 

2. It doesn't backup everything.

3. While backing up, it takes up resources of your account if you are in shared hosting which can put a strain on your website.
