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:

I send all of my backups to Dropbox and then I have Dropbox installed on my computer. So Dropbox automatically downloads the backups from Dropbox to my computer. I then use Akeeba Extract Wizard to extract the backups from the Dropbox folder on my computer. This has worked before but now I can´t extract the archives anymore. It works a while and then I get an error "Invalid archive format" and the extraction aborts.

If I download the archives with FTP from my site to my computer and then try to extract it, then it works, but it doesn´t work when it goes via Dropbox.

First check the file sizes of the files in Dropbox and downloaded via FTP, for the same backup attempt. They should match 100%, up to the very last byte. My guess is that you have a problem when the backup archive is being uploaded to Dropbox, ending up with a truncated archive which cannot be extracted.

If you cannot perform the test I outlined above, please ZIP and attach your backup log file from the backup attempt which uploads to Dropbox so that I can take a look.

I have now compared the files and the size matched on all of them, but I only compared down to the kb.

I have attached my log file.

I see that you have a multi-part archive consisting of 23 parts. Please make sure that all parts (.jpa, .j01, ...., .j22) are present on the same folder when trying to extract the backup archive. It would also be a very good idea trying to extract the archive with both Akeeba eXtract Wizard and Kickstart. The latter can run locally using WAMPserver, XAMPP or MAMP depending on your operating system. In the meantime I did try taking a backup and have it transferred with Dropbox. It seems to work just fine on both my Mac OS X machine (extracted with Kickstart) and my Windows 7 machine (extracted with Akeeba eXtract Wizard and Kickstart). My archive was a single part archive, but this shouldn't make any difference.

It started working again when I set down the split archive size from 35 MB to 32 MB.

For what is worth, I think there is a bug in eXtract Wizard with some (but not all, it seems) split archives. I had this issue myself today. When I used Kickstart everything worked just fine, though.
