Hello.

In last few months I had problems with auto backup plugin. It just creates new backups without any order, I tried to change backup interval from one week to 15 days, but nothing worked.

Actually, everything looked fine, but, instead of one backup file every 7 or 15 days I got hundreds of backup files, sometimes every minute, or every few seconds new backup. I needed to empty GB's of backup files from "backup" folder.

So, finally I turned off auto backup plugin. My thought is this, when auto backup plugin is on and also cache_html is on when auto backup needs to run it adds this to html body of page:

        // 

And if cache_html plugin cache that page at that time it will serve page with that script to every visitor, so with every new load of page backup is created.

Maybe I am wrong, but I have no other explanation.

I hope this will help.

Best regards.

Best you file a ticket on the issue ticket and please re-try with the 1.4.6 RC1 as well. If it will be fixed it will be there. 1.4.5.x does not get any updates anymore.

Update: I just tried with the RC1 and could not reproduce it. Are you sure you have set an interval and a number of backups to keep on the auto backup options?

Your analysis is correct. The page should not be cached if the ajax code is present. That will be fixed shortly.

There is a side-effect of the fix, though. If there are no un-cached page requests the backup will not get run. Probably not an issue, though, since that means the site has been static.
