We recently purchased UpdraftPlus Premium for backing up our WordPress sites, and while it’s working fine on our smaller sites, it seems to be having trouble on our large, main website.

Looking through the log file, some of the errors appear to be possible bugs with UpdraftPlus:

13694.194 (4) ERROR: backblaze: Failed to upload file: backup_2019-07-26-0300_Long_Road_Sixth_Form_College_[redacted]-uploads16.zip

Specifically the error “string does not start with quote (line: 113, file: /home/wwwlongroad/public_html/wp-content/plugins/updraftplus/includes/Backblaze/CurlClient.php)” seems like it might be a bug in your software, is there a fix available for this?

EDIT: I did a google search for that error message and came up with this link which seems to be part of the Backblaze B2 SDK: https://github.com/Backblaze/b2-sdk-java/blob/master/core/src/main/java/com/backblaze/b2/json/B2JsonReader.java

So it seems like this response is coming from Backblaze in response to an improperly formatted API request from UpdraftPlus?

Hi James,

I’ve not seen that before, and the Backblaze API documentation doesn’t mention the error code. But, it seems like it can’t be guessed. If you edit the file wp-content/plugins/updraftplus/includes/Backblaze/CurlClient.php, go down to lines 260 and 263 inside the method uploadLargeFinish(), and change…
```
			'json'	=> array(
				'fileId'		=> $options['FileId'],
				'partSha1Array' => $options['FilePartSha1Array'],
			),
```
to:
```
			'json'	=> array(
				'fileId'		=> (string) $options['FileId'],
				'partSha1Array' => (string) $options['FilePartSha1Array'],
			),
```
(i.e. addition of (string) twice), then, does that fix it?

I’ve made your suggested changes and am trying a backup again now. It takes quite a while to run though, so I may not have an answer for you as to whether it worked until Monday.

So yeah that’s not quite right:

0463.832 (0) PHP event: code E_NOTICE: Array to string conversion (line 262, wp-content/plugins/updraftplus/includes/Backblaze/CurlClient.php)
0464.420 (0) Backblaze: Exception in uploadLargeFinish(): 400, Message: array should start with bracket but found: ” (line: 113, file: /home/wwwlongroad/public_html/wp-content/plugins/updraftplus/includes/Backblaze/CurlClient.php)

I’m thinking it only wants the first one to be casted to string? I’ll try that.

Yes, that makes sense.

I think that’s got it:

0706.263 (0) Backblaze chunked upload: 100 % uploaded (79)
0707.654 (0) Backblaze: upload: success (b2_finish_large_file called successfully; chunks=79, file ID returned=[redacted], size=409838436)
0707.662 (0) Recording as successfully uploaded: backup_2019-07-26-1259_Long_Road_Sixth_Form_College_[redacted]-uploads.zip
0707.683 (0) Deleting local file: backup_2019-07-26-1259_Long_Road_Sixth_Form_College_[redacted]-uploads.zip: OK

I’ll let you know once the full backup has completed but it looks good so far.

To know if that’s the same problem or a different one, we’d need to see the whole log file (or at least, the part dealing with the upload of ‘chunk 1’), to see what happened with that.

Hi,

Thank you. (We removed the log file after downloading it as it was getting in the way when navigating the topic!).

There appears to be a different issue there. Backblaze appears to have had some internal problems (there are some “too busy” errors), and then it seems to have forgotten about one of the chunks on one of the files; a situation UD doesn’t know how to handle. We’re doing some tests to see what their API will let us detect, so that we can intelligently resend the necessary bits and not too much. We will be back in touch when there’s something to test.

David
