I have purchased the WordPress Backup to Dropbox zip backup plug-in few months ago. After I purchased, it backup my entire site to Dropbox (as a zip). But since a few months ago (with WordPress 3.5.1 and 3.5.2), this plug-in never completes the backup. All the scheduled backup only shows following log.
00:30:11: Your time limit is 600 seconds and your memory limit is 128M
00:30:11: Backup started on Monday July 8, 2013.
If I wait for a 6 hours, nothing backup, it only shows above log.
If I manually run the backup, it goes to 11% and never complete. Is it my server (VPS) issue?
I think it's not an issue with the Cron, because if I schedule posts, they published without any issue. Also I added following code to my htacess file.
Allow from All
Moreover I have disabled all other plug-ins and test WPB2D, but not give a positive result.
