FastBit Error

If a overnight backup fails, and at the end of the log it says "FastPitch Error" it means that the cache folder got corrupted during backup.
This can be caused by various things such as a virus scan scanning the folder (Virus scans should never run during backup) or another backup software is backing up that directory.
In either case, disable the software from scanning the cache folder then clear out the cache.
To do this, click on the Home button, then click on the 2 down arrows next to Settings, then click Advanced, then click Emtpy Folder under Temporary Backup Files.
