Fantastic plugin, but there's something strange about the size of the compressed files. On my server, they should be around 150MB, but the zipped file is showing only 15MB.
To test things out, I've created a job that is only backing-up plugins and uploads folders (no database), with it sending the zip file to an S3 account. The job is completing, but I'm getting this in the log file:
[04-Mar-2013 11:43:24] Archive size is 10.79 MB.
[04-Mar-2013 11:43:24] 2322 Files with 46.11 MB in Archive.
when it completes, sure enough, the archive size is 10.79MB. Looking at my server, there are 46MB of files that should have been backed up.
I've tried this on a couple of websites and have checked with my hosting provider that there's nothing odd going on at their end.
