win8 backups

Is there anyway to reduce the size of your computers backup using WIndows 8? I.e. compression?

And also are there any free services to backup a copy of your computer (that could be restored) online to the cloud? Reducing the need for any additional storage?

Hi.

Tell us how many GBs you are trying to save and why?
Image programs usually use compression by default. Windows backup does not, but you could use an NTFS compressed drive as the target, that would be sufficient.

About 5Gb, and the reason why is the external drive doesnt have enough capacity to store the backup so without buying another drive it doesnt fit.

I'll read the link but can you elaborate how this works? If the capacity on the USB is say 60Gb, but the backup is a total of 65Gb, how will this work? Sorry to sound naive. But surely it needs enough capacity to store it to first, and then perhaps you can compress it after its been written to that drive?

Can you preconfigure the drive for compression? So its compressing anything you copy from the PC in real time? So copying 20Gb of data from the computer onto an NTFS compressed drive may result in only 15Gb, hence it would fit? If you have to copy the data from PC to USB first, then run the compression, I cant see how this would work, as the backup tool is writing as one file, you cant do it piece by piece.
