The Acronis True Image 2013 backup software in online ‘real time’ mode has caused me some problems since the 28th May when I enabled it, with the Weather Display application hanging  and therefore generating a Clientraw data received error on the web site. I have reverted back to incremental backups every 24 hours, bit of a shame that the backup software won’t work as advertised (plenty of user comments on this when googled), but at least this method works.
