[Plugin: BackWPup] Dropbox Backup Stopped Working

Thank you, Daniel!!! New version 1.6.1 works just perfectly also with Dropbox! Absolutely AWESOME! Thanx for your hard work!!!

oh oh .. a new version somewhere then ?

Version 1.6.1 working great with Dropbox! ??

Thank you Daniel for your excellent plugin and awesome support.

1.6.1 is *not* working with Dropbox for me.

The backup log shows that after authenticating with Dropbox, this error is returned:
[ERROR] DropBox API: Invalid response.

I’ve tried deleting authentication and re-doing, but it makes no difference.

I have worked with Daniel about this dropbox issue, he knows where is the problem, at least he has my account to check how to fix it ( it depends on the size of the backup actually )

The zipped file that BackWPup is trying to send to Dropbox is only 12.3MB (at the moment) – doesn’t seem outrageous…

Just discovered that a plugin is conflicting with the Dropbox authentication. Haven’t figured out yet which plugin it is. Will track it soon.

Simple Twitter Connect plugin is found to have problems with its authentication. Deactivating it solves the issue.

I don’t use “Simple Twitter Connect”. But I do use Twitter Widget and WordTwit.

Hi Daniel:

Nice work so far. Thanx for the update. Just want to add my experience to the debugging:

Everything goes seems to go well until the zipped backupfiles is being to be moved to dropbox

My log looks like this:

2011-03-21 13:52.15: Authed to DropBox from jesper s?holm
2011-03-21 13:52.15: Free Space on DropBox: 1.91 GB

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 72786751 bytes) in /home/<user>/public_html/<domainfolder>/wp-content/plugins/backwpup/app/libs/dropbox.php on line 425

Line 425 is this:
$content .= file_get_contents($filePath);

The problem shouldn’t be the memory size as the allowed momory size seems to exceeds the memory need.

Afterwards I did another test. I only backup’ed my Atahualpa theme folder + the DBs. This resulted in a succesful backup of only 1.19 MB:

2011-03-21 14:14.12: Free Space on DropBox: 1.91 GB
2011-03-21 14:14.15: Backup File transferred to DropBox.
2011-03-21 14:14.15: Backup Archive File size is 1.19 MB
2011-03-21 14:14.15: Job done in 5 sec.

Could it be a php time out error that interrupts the file transfer to dropbox. At least I got the “fatal error” way before php would have been able to finish the file transfer to Dropbox I think. (Although a server to server file transfer might be much faster than what I expect for a 90 MB file transfer. :-] )

Anyway, hope this might help a little.

Further to my test report:

I tested a full backup with FTP. This worked great:

2011-03-21 14:49.50: Backup Archive File size is 69.42 MB
2011-03-21 14:49.50: Job done in 220 sec.

Perhaps you need to return some error message to the logging if the setup is wrong. Initially, my process stalled because I had added a “/” to the directory path in the FTP setup.

And now we are talking ‘Embesserungen’:

It would be helpful if the Dropbox setting box for each backup would show which Dropbox username/email is being used. (Especially useful, if you’re returning to the menu after some time.)

And what would be really cool would be a direct download link to the latest backup file. If the Dropbox API allows. Maybe then a very userfriendly restore function is just around the corner! ??

jes. the problem is in moment the dropbox api that dont’t support chunkt uploads!

i will test some thinks to reduce the memory usage.

Username und Password i can’t use that is why dropbox have no give my plugin production status.

the direkt download link is on the first page if the job works correctly

Navjot Singh: twiiter has a oauth autenticas as drobox too.

Any idea when this incompatibility with Simple Twitter Connect will be fixed?

I tried backing up to a free FTP account from DriveHQ which worked without any problem.

When I tried to back up to Dropbox it gave me the following error,

Fatal error: Out of memory (allocated 23592960) (tried to allocate 43635028 bytes) in /home2/virtualp/public_html/wp-content/plugins/backwpup/app/libs/dropbox.php on line 425

My web host increased the memory limit but the problem didn’t disappear
