I did my first backup using Windows 7 built-in backup and restore last week. Chose to let windows decide what to backup and also do a system image (basically the default settings). It took quite a long time, almost 4 hours.
Tonight it did its weekly scheduled backup and another sytem image. Since it only copied any new files that part went fast but the system image took a long time, almost 1.5 hours.
When I look at manage space the system image is using 124GB. This seems huge. I thought it should be maybe 20GB or so. Data files being backed up are 71GB. Other files are 4GB for a total of almost 200GB.
This is a relatively new computer so why is the system image so large? Is there a way to verify that it should be that large? Will it always take so long to do the system image?
