Hi @elsieblogger,
Thank you for sharing the detailed log.
As a first step, you can try rolling back to the previous version to confirm whether the issue is related to the recent update. You can download the older version here:
https://ww.wp.xz.cn/plugins/backwpup/advanced/
Please download version 5.6.5 and install it over the current version (you do not need to delete the plugin).
Once done, try running the backup again and see if it completes without the memory error. If it works correctly on 5.6.5, please let me know and we can continue investigating the behavior in 5.6.6.
Looking forward to your update.
Per your direction, I downloaded the version 5.6.5 and uploaded it to my website. My backups are working perfectly with this older version. I will hold off updating to a newer (current) version until I’m sure the issue has been resolved in the newest version. In the meantime, I’ll still be able to do my backups.
Thanks for giving me direction, and good luck in resolving the issue.
I’ll mark this issue as Resolved once the newest version is tested. In the meantime, I suspect that the older version will hold us over for the time being.

Hi @elsieblogger,
Just wanted to follow up on this.
At the moment, we haven’t been able to identify a clear root cause, mainly because we don’t have a reliable way to reproduce the issue on our end.
However, one of the users reported that optimizing/cleaning up the database helped resolve the same issue:
https://ww.wp.xz.cn/support/topic/errors-with-version-5-6-6/#post-18852429
Could you please try that and let me know if it makes any difference?
If the issue still persists, I would recommend reaching out to our support team directly so we can take a closer look at your specific setup and investigate this further.
Best regards,
I have followed your direction and have optimized/cleaned up the database at my web host IONOS. I then updated my BackWPup from version 5.6.5 to version 5.6.6. Unfortunately this has made no difference, with the database backup still failing. Below is the error report (the “XXXXX” is my editing over the actual numbers):

Using version 5.6.5, gives a backup file size of 3,090 KB (pretty typical). The flawed backup with version 5.6.6 is only 1.1 KB. I will again return to using version 5.6.5 until this issue is resolved.
For reference, I’m using Windows 11, 64 bit, fully up to date. The PC is a Dell XPS 8930 with 32mb RAM. As mentioned above, I use IONOS for my web hosting (since 2006), I have a small blog using WordPress 6.9.4. It is NOT a commercial website and has but a modest following. As you can see, my database is quite small. Please be advised though, I am NOT an IT guy or computer guru. Thus, I am limited into what I can accomplish in dealing with this issue.
I’ve noted that several folks have claimed to have what appears to be the same issue. I think it unlikely that all these folks have suddenly started getting errors at the same time upon using this new version of software. I strongly suspect that some obviously unnoticed bug is in this new version since all the prior versions aren’t producing this error. Indeed, I have been using BackWPup for several years now, with NO issues until this one using version 5.6.6.
Good luck, and I am hopeful that this can be resolved.
I have reinstalled BackWPup version 5.6.5 and the backups are again perfect and without error. I’ll keep using this version until I see a newer version of BackWPup that claims to have fixed this issue.
Since I am using the free version of BackWPup, as I understand I can only use this forum for help, therefore am unable to contact support directly.

Hi @elsieblogger,
To help us investigate this more thoroughly, it would be best if you could reach out to our plugin support team directly. You can do this from the Contact Support option available at the bottom-right inside the BackWPup interface.
Looking forward to your message.
I’m experiencing the same issues with version 5.6.6 with multiple sites on different hosts. I’ll rollback to 5.6.5 for now. Hopefully this issue will resolve in 5.6.7.?

Hi @elsieblogger,
Just following up on this.
We haven’t received a support request from your side yet. If the issue is still ongoing, I’d recommend reaching out to us directly using the Contact Support option inside the plugin so we can investigate this more closely.
For now, I’ll go ahead and close this thread. Feel free to open a new one anytime or contact us directly if you still need help.
Best regards,
I have tried repeatedly to contact you directly via the Contact Support option inside the plugin. Unfortunately that isn’t working. The window opens and asked that cookies be allowed. I click the button, the screen changes for a few seconds, then brings me back to the cookies permission pop-up. Have tried repeatedly to both allow and disallow cookies, but every attempt fails, and I’m stuck at the cookies permission pop-up. I’m starting to lose all confidence in BackWPup’s programming skills! So sad . . . . 🙁
P.S. My thread has been marked as Resolved. It has NOT been resolved. I am making successful backups by using the older version 5.6.5.
There seems to be confusion as to the status of this topic. Someone (besides myself) had marked this topic as resolved even though it hasn’t been. I changed that status to NOT resolved so it remains open. The other issue I added above was my failure to follow up with direct contact with BackWPup as requested by WPM Support due to not being able to get past the Cookies pop-up on the Contact Support window. At this point I’m apparently at a dead end.
I have realized that I have created a second issue within this thread about Contact Support. So I have started a new thread specifically about that issue. Now this thread can exist solely for the database back-up issue.

Hi @elsieblogger,
Just following up on this.
Did you get a chance to reach out to us using the Contact Support option in the plugin?
This will really help us take a closer look at your setup and investigate the memory issue properly.
Please let me know once you’ve sent the request, and we’ll take it from there.
Best regards,
Yes, I managed to get to your support via the Contact Support option via the plugin. Unfortunately I have no joy. I never actually got to a real person. It appeared to be a AI robot, and it kept asking me to do this and that, most (if not all) I had already done. I couldn’t seem to get a straight answer, but rather just an endless list of things to do including trying to get my hosting website to do this and that (things that I’m not able to do myself). I was not asked for any particular information as to my configuration. I don’t even know if by “configuration” I’m asked for my PC configs, or my small blog website configs (which would be with WordPress) or ???. In other words, I’m at a loss as to what information y’all need as I haven’t been told what.
I’ve already spent way too many hours chasing this issue from my end. But my engineering background (though mechanical) keeps telling me that when the older version 5.6.5 is working just fine, but then the next version produces a problem, that it’s not necessarily my configuration or whatever causing the problem. Obviously something has changed in the BackWPup code for 5.6.6 that has now created a problem, at least with some users.
I’m not a software expert or IT guy, so I’m limited as to what I can do. At this point I’ll just continue using what IS working for me . . . version 5.6.5.
I do appreciate your interest in resolving this, but apparently the coders are hoping that the users can solve the problem for them. Hopefully one of the folks is knowledgeable enough to provide the information that your coders can use to solve the issue.
