When I try to get an already uploaded backup I get this

Error
The backup archive could not be located

Description of my issue: Since I upgraded to 4.4.0 version I get those errors. If I try on a site that has not been upgraded (version 4.3.1) everything is working ok.

Thanks!

Ok!

I've been able to upload to S3 by disabling multipart uploads with v2 and v4 signature method.

One strange thing is that all my logs that are located in administrator/components/com_akeeba/backup are empty - 0 byte.

And if I start ALICE, I get 2 warnings:

Additional database - Wrong access details
Warning
Could not detect the used profile, test skipped

Additional database - Joomla database inclusion
Warning
Could not detect the used profile, test skipped

Thanks for that fast support ;-)

Hi Nicholas,

I modified the configuration to get something in the logs. I joined a zip file containing 2 screen captures and one compressed logs file. You'll find everything you need I think.

This being said, I must tell you that after a first try, from the logs scanned by ALICE, I got this error message:

Post-processing engine and archive part size
Warning
A post-processing engine is found, but no part size is set; this could lead to timeout issues
Set a part size inside backup profile configuration.

So I just modify the Part size to ~100MB and gave another try to get that error message:

Upload cannot be initialised. Amazon S3 returned an error message: 0 :: Akeeba\Engine\Postproc\Connector\S3v4\Connector::startMultipart(): [0] The request signature we calculated does not match the signature you provided. Check your key and signing method.
Failed to process file /administrator/components/com_akeeba/backup/site-model.xxx.com-20150930-152329.jpa
Post-processing interrupted -- no more files will be transferred

Strange message that does not seem to be related to the problem.

Then I made many other tries and finally with a part size of 5 MB, it works.

I don't understand why it works with 2GB part size with version 4.3.1 on another site that is on the same server. This server is running on a full gigabit network, ssd drives, 8 cores and 24 Gigs of ram.

So for now I don't care to disable multipart uploads. My backups are not so big (500 MB to 1 Gig).

But if you can tell me what is going wrong with this, I would appreciate.

Thanks!
