Most routers have their own backup & restore on their menus.

Thanks for the replies.

I have looked at syncback and also Memo unfortunately the memo site is down for maintenance so will check it when its up. I will update when I have decided and let you all know

There are two basic types of backup - File and Disk/Partition..... You seem to require the latter.
Acronis true Image seems to be the "paid for" standard these days, whilst Macrium Reflect and EaseUS ToDo seem to be the favourite freebies.
Ideally, you should create a series of images of each drive/partition - A pristine copy, a copy where all your normal soft/hardware is installed and perhaps a weekly image.

Whilst image backups are lifesavers, you should also consider a "file" backup regime such as Windows Backup or similar as well.
