Weather PC RAM increased from 2Gb to 4Gb due to memory resource issues when running Acronis back-up software in ‘real time online’ mode, this memory increase has resolved the problem and now instead of making Incremental backups once per day, the system is creating a constant mirror of the ‘C’ drive to the second hard drive which has also been made bootable.

Hopefully these resilience measures will not be needed, but if history does repeat itself I’m better prepared than last time.
