Hi! Can we still use Akeeba Extract Wizard 3.3? (Windows 10)

If yes, we get  an error message "Can't read header information, your archive is corrupt'. I tried serveral different jps files, download through browser and also FTP. I also use the correct password.

besides the extract Wizard, is there an other way to extract jps files? We could restore the site somewhere, but when we only need some files from the backup that would seem a bit overdone?

We could also switch to zip backups maybe. But jps is also encrypted so more secure on a remote cloud service., right?

Kind regards,
Jip

As noted in the release notes of Akeeba Backup 4.6.0, you can no longer use eXtract Wizard to extract JPS archives created by Akeeba Backup 4.6.0 or later, Akeeba Backup for WordPress 1.7.0 or later and Akeeba Solo 1.7.0 or later.

If you're wondering why, we made some important changes in the cryptography of JPS archives to make them more resistant to cryptanalysis. These changes have affected how the encryption key is applied to the raw data, a change eXtract Wizard is unaware of. As we had announced all the way back in 2012 we no longer maintain eXtract Wizard so these changes will not be applied to it.

We recommend that our clients use Kickstart to extract the backup archive. You just need a local, PHP-capable web server such as MAMP, XAMP or WAMPserver. You do NOT need to fully restore a site to extract it! Once you get to the point where Kickstart asks you to run the restoration script just close Kickstart's tab and delete kickstart.php and the archive. Do remember that, as Kickstart informs you every single time you run it, KICKSTART ONLY EXTRACTS THE BACKUP ARCHIVE, IT DOES NOT –REPEAT: NOT– RESTORE THE SITE.

Also, no, please, do NOT use ZIP. It's the worst file format you can use, bloated and unencrypted.

If you really want to use an unencrypted file format use JPA. In any case, eXtract Wizard still works fine with JPA and ZIP files generated by Akeeba Backup, Akeeba Backup for WordPress and Akeeba Solo. This won't change in the foreseeable future.

Ok thanks! Unsing kickstart only to extract (not complete site restore) is indeed a good option. Did not realize this.

I do prefer jps because I want to keep the backups secure even if the external cloud service we store our backups is somehow compromised.

W'll stay clear of zip! ;-)
