Version 1.3.5. Backup job configured for 0200 every day never runs. Settings are set for using WP-Cron and using Crontrol, it shows
backwpup_cron  01/01/70 00:00:00 (now) 300 (5 minutes)
and your custom interval:
backwpup_int 300 (5 minutes) BackWPup
So it looks like it is correct? Any way to troubleshoot this?
2 other issues I noted:
Your plugin created a folder:
along side the logs folder:
What is this?
Finally, I've noticed that if I try to manually run the configured backup job, the 'output' screen will usually 'lock' and stop the job from completing (forcing a clear). If I start the manual job and then navigate away from the output screen, the job completes in about 8 seconds. Can you amend the manual job output to just total the files as it looks like listing every file is causing problems.
BTW, thanks for your great plug in!
