EXTREMELY IMPORTANT: Please attach a ZIP file containing your Akeeba Backup log file in order for us to help you with any backup or restoration issue. If the file is over 2Mb, please upload it on your server and post a link to it.

Description of my issue:

Hi Nik.

I am wondering if there are any tools to enable a manual deconstruction/unpack/unzip/separate exercise on a JPA backup that just refuses to unpack using kickstart and the extract wizard.

I have been forced to recover a site using an older backup, which has resolved the immediate pressure, but I would like to try and recover some of the updated material from the 'corrupt' archive.

I can make the bad archive available if there is any point in taking a look at it, but I do not have the creation log files as client pressure forced me to wipe the site and rebuild from scratch ASAP.

I will be scheduling offsite dumps of logs files as well as archives in future, but for now, is there any hope of recovering / expanding /exploring the duff archive please ???

There is a last resort. Extract the attached ZIP file on your local (IMPORTANT!) server. Rename you archive to problem.jpa and if you have other part files to problem.j01, problem.j02 etc. Put them alongside the extract.php file.

Before proceeding make sure that your max_execution_time is set 240 in your server's php.ini file. If not, set it now and restart the local server.

Now try running extract.php from your browser and keep your fingers crossed. It will try to salvage whatever it can from the archive into the "target" directory.

Thanks Nik.

As soon as I can get on to a local machine with access to the archive I will give it a go.
Please close this ticket for now - Thanks once again!
