Backblaze: Exception in uploadLargeFinish()

[Jason DearParticipant]

We’re now on version 2.16.18.24 of UpdraftPlus premium and we’re seeing a new type of error regarding uploading backups to our Backblaze cloud storage.

Here is an excerpt from the log file:

0004.183 (0) Total database tables backed up: 63 (backup_2019-10-02-0002_Long_Road_Sixth_Form_College_d008afabed22-db.gz, size: 6190902, sha1: ce4d442439b0cf16240efb422f7d4e61152c7ca2, sha256: 317850c9f65c5212f5a2a7f08fe21b6b74338388cb3c869ac7901f2d491523e8)

This is repeated several times throughout the log file.

I’m assuming that similar to the previous issue that we had that this is a Backblaze error condition that your plugin currently does not handle?

Please could you update UpdraftPlus to gracefully handle this error situation?

Hi,

Please can you send us full copy of the backup log?
Please use Pastebin or Dropbox for the log and send us the link here.

Hi Jason,

Can you try to upgrade to your PHP version to latest (7.x)?
See if that fixes the issue.

I’ve updated PHP to 7.3 and will monitor the situation. A manual backup succeeded.

Thanks.

Hi,

I’ve asked one of our developers to look at this topic.

Hi,

I’m looking into this and just trying to get some more information.

Do you have the define UPDRAFTPLUS_UPLOAD_CHUNKSIZE defined any where on your site and if so whats it’s value?

Best Wishes,

Ashley

[Jason DearParticipant]

Not that I’m aware. However, since upgrading to PHP 7.3 we have not experienced any further problems so far. I will continue to monitor the situation.

Hi,

Thanks for the reply.

I’ve managed to track down the issue and it will be fixed in the next release.

Best Wishes,

Ashley
