5.1.1 files backup bug on GoDaddy

[scythe000]

Here's the error i get:

The following errors were detected:

• Error: PCLZIP_ERR_MISSING_FILE (-4) : File 'stats/logs' does not exist
  

Looks like it's trying to backup the stats directory which is probably casuing issues. I'd recommend either coding it out, or better, give us an option to exclude directories.
