Hello,

Apparently, the memory limit is maximum 32M (from what I see in the host documentation) while Next Gen Gallery reports a real limit of 40M.

This is a shared server webhost so I don't really have the option to modify the memory limit, it is enforced by the provider.

Maybe the best for me is to reinstall the old release of WP DB Backup.

Thanks a lot for your help anyway! I have sent you a donation for this great plugin!

Yes, in previous versions of the plugin what happened is that the gzipping was done incrementally, which worked better for larger total database sizes, but it had the unfortunate result of incorrectly reporting the total unzipped file size.

With the wrong size reported, some common gzip clients failed to open the gzipped file, and people would think that there was something wrong with the gzipped file (when really, they just needed a more robust gzip tool).

So in the latest version of the plugin, the gzipping occurs to the completed backup file, which seems to fail if someone has low memory available to PHP. Could you check to see if your PHP memory is set to 32M in php.ini, instead of 64M which is typically recommended for WordPress?

Hello,

Since I have performed the upgrade to the latest release, the backuped file isn't compressed anymore.

I have tried to set the mod_evasive to true and increase the delay to 10.000 but still the file isn't compressed.

I suspect that it is related to the file size (around 10 M) because on other file sizes where the DB is smaller, the file is gzipped without any issue.

Has there been any modification in the way the file gets compressed between latest two releases?

Thanks a lot for your brilliant plugin, very very usefull!

It used to automatically save the databases on my serve but it just stopped recently.

I'm not sure what you mean. WP-DB-Backup has never had the option to automatically save backups to the server.

Could you be using another plugin?

I am having a problem getting this plugin to work. It used to automatically save the databases on my serve but it just stopped recently. I am using 2.8.6 with All In One SEO and Contact Form as well. I tried disabling these plugins but still didn't work. Any suggestions?

I had this issue (initiate manual backup and was being redirected to home page)

The problem for me was a plugin called wordpress-firewall. I added an exception to its rules and all was well.

About 2 weeks ago, I stopped getting the automated email backup.

When I tried to backup the database manually, using any option (save to server, download, email), it would not work. The progress bar would eventually stop showing progress even if I left the window open for hours.

After reading this forum, I deactivated the Contact Form 7 and All in One SEO plugins, and the WB DB Backup plugin would successfully save the backup to the server manually. I never received an email with the database backup, but it could be that it has grown too large to send in email. The site has about 5600 posts and about 37,000 comments.

I have had the three plugins (WB DB Backup, All in One SEO, Contact Form 7) working together for a few months now. I'm not sure why the combo would quit playing together nicely two weeks ago.

Here are the versions that I'm using.

Wordpress v2.8.6
WP DB Backup v2.2.2
Contact Form 7 v2.1.1
All in One SEO v1.6.10.1

Hi filosofo,
the plugin works perfectly when downloading the backup file to my pc, when using browser Firefox.
But! It does not work in Opera!!!
Cheers, Josef

After upgrade the plugin doesn't work anymore. Whenever i try to backup it redirects me to my homepage.

I have reinstalled it several times but still. Any suggestions?

jokkesvin, are you extracting the gzipped file with a gzip tool, before trying to open it in a text editor?

Have you tried the version I linked to above? What was the result?

I get the same bug. Just a 4 kb back-up file :( Any posibility of a fix? This is what the file contains upon opening it in text edit:

# WordPress MySQL database backup
#
# Generated: Tuesday 27. October 2009 15:43 CET
# Hostname: xxxxxxxxx
# Database: xxxxxxxxxxx
# ----------------------------------

However, it's working when I set it to mail me the file. What gives?

I have a similar problem. I got an email just fine from two sites that have Contact Form 7 -- even though the backup page seemed to hang at the "preparing email" stage.

But on a very large site I'm trying to backup, both email and download hung at that point with no evidence that it was completed.

I can't find the backup_81a5d folder you all are referring to. Where is this located?

I am using All In One SEO Pack as well.
However on 2 of my blogs I haven't had any problems, only on the 3rd.

After further research, I've found that your plugin is incompatible with both Contact Form 7 and All In One SEO Pack.

Do you have any ideas about why this might be the case?

Both of them are very commonly used plugins and are likely to affect many users.

Okay, I disabled all other plugins besides yours and tried the backup. It worked without a problem.

I apologize for taking your time. I should have done this sooner.

But I have no idea which plugin is causing the issue. Here's a list of what I have installed. Do you have any ideas about which plugin might be conflicting?

It still does not work for me.

When I execute the backup, the blue progress bar gets all the way to the end. The message underneath says "Backup complete, preparing backup for download". However, nothing happens (nothing is downloaded). If I click on the linked "backup" in the sentence above, I get an Internal Server Error 500.

You can see a picture of what I'm talking about here.

When I check my backup_81a5d folder, I can see that the manual backups are being created successfully. But for some reason they will not download.

Also, as I mentioned previously, I am not receiving email backups. And I don't think the scheduling function is working, because although I have set it to make weekly backups, I don't see any backups created in the backup_81a5d folder for that time period.

WOOHOO! Well, that does at least email the backup file to me without giving an error, nice job.

The email cam through and it looks like the attachment is the right size too.

I will let you know later if the scheduling is working or not, but expect that might not be fixed yet.

Can you try the development version of the plugin to see if it solves your problems?

I've put in some changes that should correct the file size issue. You can download it here. Just copy that wp-db-backup.php file over the existing wp-db-backup.php file in the wp-db-backup/ directory.

I wondered if another plugin might be interfering, but my backup works, it's just the emailing that doesn't, and only on 1 site.

Any help possible here? Thanks.

I am using Safari 4.0.3 on Mac OS X.

What browser are you using? And timwindsor, what do you mean by "pick it up"?

I have the same problem. It downloads a 2 meg file, but when I pick it up, it's just 4k in size.

Tim

I installed the plugin but it does not work for me.

When I try to do a manual backup, the blue progress bar gets all the way to the end and it appears that it has finished. But when I click the link to download the backup, the downloaded file is only 4k when it should be 6.3MB.

However, when I look in the "backup_81a5D" folder, the backup in the folder is correct.

Also, although I have scheduled daily backups to be sent to me via email, I have not yet received a single backup via email.

So it appears that the backup happens correctly to the server, but when I attempt to either download it or have it sent by email, it doesn't work.

I am receiving email replies to comments for my blog so I know email is working.

Thanks a lot for your help.

You say that you have found answers. Could you link to the specific page?

Reply to self:

Filosofo, I 'reallocated' a block of time from my employer to this issue and have located answers at http://worldpress.org/extend/plugins/wp-db-backup/

PS: PayPal has improved your fighting fund :0)

Thank you for that clarification.

If you might go one step further here, I am on WP261 and the downloaded wp-db-backup is 215 but shows as 2.2 in plugins manager.

WIth my many other issues I have been unable to easily find why there is a version difference. Can you comment or point to explanation?

This matters to me because each time I run a backup (since my comment above) the progress hangs at random points. Aborting and retrying corrupts the blog db which I then must repair in phpMyAdmin (repair tables all).

If not version, can you suggest most common reason for this?

Thanks for you valuable time, Phil.

The bug is that it tells you the "mail application has failed" but it actually delivers it. If you're not actually getting the email, then something else is wrong.

Hope this is good place to add a question.
Filosofo, can you confirm this error is the 'bug' you are likely now working on?

On-demand backups succeed, and I can download them from the other two option (save to server & download) but the option to email them results in error:

"Backup complete, sending backup via email...
The following errors were reported: ERROR: The mail application has failed to deliver the backup."
