Hi there!
I've installed the akeeba backup professional to my wordpress site. I want to manage and upload automatic backups in zip format to and I'm unable to do this. I configure post processing using webDAV and added ( my login credentials and all other details. I'm able to take backup on local but in the finalising I'm getting a warning saying :
"Failed to process file /path-to-my-site/akeebabackupwp-1/app/backups/site-20160107-114738.sql
Post-processing interrupted -- no more files will be transferred".
Can you guys assist me whats wrong with it. I'm using antivirus plugin, After reading some forums, I disabled that plugin and tried to backup, Backing up is successful but can't get the archive folder to

Please assist me!

Thanks and regards,

You are doing something wrong :) What you entered,, is NOT a WebDAV endpoint. It's a web interface login page for Instead, you need to do something entirely different as you can read in our documentation.

Go to Akeeba Backup and select the backup profile you want to edit. Now click on Configuration. Scroll to the Post-processing Engine row. Select Upload using WebDAV. Enter the following information:
  • Username: Your email address
  • Password: Your password
  • WebDAV base URL:
  • Directory: the directory in where you want your files to be stored

For more information please consult our documentation:

Now I'm getting backing up failed error due to large size of files and less execution time, but I've already set up max_execution_time to 900 and upload_max_filesize to 500m.

Backup Halted and Will Resume Automatically
The backup operation has been halted because an error was detected. However, Akeeba Backup for WordPress will attempt to resume the backup. If you do not want to resume the backup please click the Cancel button below.

For your information, the last error message was:

AJAX Loading Error
HTTP Status: 500 (Internal Server Error)
Internal status: error
XHR ReadyState: 4
Raw server response:
(HTML containing script tags)

All right. You fixed the obvious misconfiguration but I bet that you've still not followed all of our documentation instructions for setting up uploading to remote storage. Please check out As you can read there:

We will have to change just one option: Part size for archive splitting. Select the "Custom..." option and type in 20 in the text box that appears to the right of the drop-down. This setting will split our backup archive into multiple files, the maximum size of each one being the value of this setting.

You might wonder why we need to do that. PHP always has a strict time limit, i.e. the maximum time a PHP page may process data before the web server aborts it. Uploading the backup archives to cloud storage takes time, the exact amount of which depends on the size of the file and the network speed. The time limit and the bandwidth are beyond our control, so we can change the only parameter we can touch in order to avoid timeouts: the file size. Akeeba Solo / Akeeba Backup Professional is smart enough to upload each part of the backup archive on a PHP page load of each own, so as to avoid timing out.


Backup restoration is equally easy even when your backup archive is split in small chunks. Our software will automatically figure out that you are using a split backup archive and process all backup archive parts automatically, without requiring any additional input from you.

Please note that depending on your server and how fast it can transfer files to Box you may have to adjust the part size for split archives from anything between 2Mb to 50Mb. I would recommend to start with 20Mb per the documentation and adjust accordingly: if it still fails use a lower setting, otherwise try something higher.

Also note that when requesting support it is best to provide us with the backup log file. Otherwise we are proceeding based on guesswork.
