In order to work, Akeeba Backup requires the following server software environment:
Joomla!™ and PHP version compatibilities are detailed in our Compatibility page.
MySQL 5.0.42 or later. MySQL 5.6 or later recommended. MySQL 4.x is not supported. Alternatively you may use PostgreSQL 9.1+, Microsoft SQL Server 2008+ or Microsoft Windows Azure SQL database. Akeeba Backup (since version 3.8.0) is able to backup and restore databases running on any of the above server technologies.
Minimum 24Mb of PHP
only for smaller web sites, without many
plug-ins and modules running). More is better. 32Mb to 64Mb
recommended for optimal performance on large sites. 128Mb is
recommended for sites containing deep-nested directories with
thousands of files.
Even though Akeeba Backup may run on servers with a smaller memory limit, it is unlikely that it will ever finish the backup process.
Enough available free space or quota limit to store your backup archives.
The cURL PHP module must be installed for FTP and cloud uploads to work.
As far as the browser is concerned, you can use:
Internet Explorer 9, or greater (earlier versions will not work).
Any modern version (i.e. published within the last year) of Microsoft Edge, Safari, Opera, Firefox or Google Chrome.
You are very strongly advised to disable Internet firewalls, antivirus applications and browser extensions which interfere with the site's loading such as script blockers (such as NoScript) and ad blockers (such as AdBlockPlus) only for your the domains you are backing up from and restoring to. Remember that these applications and browser extensions are designed to protect you against third party sites. As a result they are very aggressive and WILL break your own sites. We can't do anything about it: your computer and your browser are under your control alone.
