Backup fails @ 79% every time

@hapzfl
hmm, I’m not sure what goes wrong there, please go to BackWPUp -> Settings -> Logs -> Logging Level -> Debug(not translated ), re-run the job again and send us debug log.
You can get back up log at: BackWpUp -> Logs
Download the latest one, then upload it to Pastebin or dropbox.
Thanks!

Upload it to where? Do you have a link or something for Dropbox?

Hello? Anybody there? How can I get the debug report to you?

Are you sure you want me as a customer? With that support I doubt it.

After that, download the latest log file at BackWpUp -> Logs, and upload it to GDrive or Dropbox, then give me the link.

For community support on wp.org, we do support daily, so please help me, be a bit patient. Thank you so much ??

OK, I uploaded the log file to my Dropbox. But how can I share w/o having an email from you?

Be it what it is, here are some facts of creating that backup:

[11-Jul-2020 19:35:27] Backup archive created.
[11-Jul-2020 19:35:27] Archive size is 19.19 GB.
[11-Jul-2020 19:35:27] 25596 Files with 19.39 GB in Archive.
[11-Jul-2020 19:35:27] Restart after 51 seconds.

[11-Jul-2020 19:35:28] DEPRECATED: Invalid characters passed for attempted conversion, these have been ignored
[11-Jul-2020 19:35:28] Job done in 23789 seconds.

That’s almost 7 hours!
And the reason seems to be that most of my /wp-content/uploads/folder/files have restarts like: Restart after 70 seconds up tp about 30+ times!

So instead of a couple of minutes the back-up took 6.6 hours.
I am running this web site for test purposes only on my PC: Windows 10 with XAMPP.

And there is another strange problem: the download of the finished job file does not work. The downloaded zip file in my “download” folder stays empty! This is really strange as the file /wp-content/uploads/backwpup-bb7406-backups/2020-07-11_12-58-59_D25XIBRM03.zip has a size of 19.39 GB and I can copy and paste it into my “download” folder w/o a problem.
So something is wrong with that download procedure too.

I have not yet tested what happens if I upload the zip file into a clean WP installation. The database sql file that was created hopefully works.

@hapzfl
just wait for it created, since your site is pretty large, about 20gb.

The downloaded zip file in my “download” folder stays empty!

you would also need wait too, the download should also works.

This warning will be fixed in the next 3.7.2 update, please no worry.

Almost 7 hours for a backup when competitors can do it in minutes is just not feasible as the site is still in the early stages and things will get worse.

The same applies to the download; that time is way too long if I can do it in minutes not using your download app.

I got into trying BackWPup based on a recommendation/tutorial by Elementor. That video shows using BackWPup when creating a staging environment by using “Local” and uploading the zip file into that local WP. That failed in my case because although it seems to load the zip file it does not recognize the sql file.
My suspicion is that this is a file naming problem but I don’t know what the proper file name is supposed to be and rerunning the backup, possibly several times, to figure out what is going on is just too time consuming.

so I’m going to close the issue here.

hmm please check carefully if you have done full backup, about 20gb with other plugins in few minutes, since some plugin will backup your themes and plugins only ^^

So I’m going to close the issue here ^^

Well, you never explained what causes the many restarts!

@hapzfl
Many restarts are a must.
Because the webserver has set the value of PHP script max execution time, for example, 30 seconds, in case a PHP script runs longer than that limit, the web server will force stop the PHP process and it leads to errors.

For a long-running process, like backup a website, BackWPUp will need to split the long-running process into multiple short-running processes, in this way, the server will not force stop the job and also it helps reduce server load.

I ran the backup again over night. Again 6.6 hrs.

Then I downloaded the zip file and again it did not work. The result was a 1,023 KB zip file that cannot be opened.
The file stored in the WP directory is again 20 GB, i.e. the download is NOT working.
