It probably depends on what you were doing with Ghost, but for me, Clonezilla is the replacement: https://clonezilla.org/

I still use Ghost, its been maintained and updated over the years and supports at least Windows 7. I haven't deployed any Windows 10 machines yet, so I don't know if it supports that.

Its nice because with NTFS it saves files and all of their attributes and not empty space.

Company I worked for moved from Ghost over to ImageX (aka WAIK: Windows Automated Installation Kit) which worked well since we needed it for MDT or Microsoft Deployment Toolkit. They built a GUI for ImageX and it was more compressed than Ghost for the same hard drives.

I either use dd or Aomei Partition Assistant

We ended up using Acronis.
