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:
Backup will not extract on localhost

Have tried multiple times
Each time has the same invalid headers message
Tried with kickstart, kickstart-pro and xtractwizard
Tried with JPA and Zip
Made sure to exclude php.ini and .htaccess from the backup

First, is it possible to take another backup? If it is, switch from ZIP to JPA and take a new backup.

You've hit on a bug I found out last week regarding multipart ZIP files (generated whenever there's a non-zero part size). The multipart header overwrites the first file's signature and causes this problem. If taking a new backup is out of the question you can send me the ZIP file and I'll fix the header so you can extract it.

The first three attempts were with JPA - only switched to zip as a final attempt to fix it.

Will send you the zip

I think I see where the problem is. The angie.jpa file is corrupt, thus breaking the backup archive (the installation folder files included in the backup have the wrong size, upwards of 4Gb). Try reinstalling Akeeba Backup on that site and take a new backup with the JPA format. If that fails please post back.

Is there any chance I can get direct access to that site?

I can actually see what the problem is but it doesn't make any sense. Every time we use fseek() to go to a specific file offset the filesystem pointer ends up one byte BEFORE the requested position. Either that or gzip returns all data truncated by one byte. It's impossible to say which of the two is the actual problem because they are not supposed to occur but they are the only explanations to what I am seeing. I think it's more plausible that the gzip library on the server is FUBAR.

I don't have a solution to that :(
