One of my laptops now serves as a dedicated Ubuntu machine, acting as a perfect test device for testing apps and self-hosted services. But there’s a severe lack of disk backup and system image creation apps in the operating system. You can understand my frustration with copying each file from a directory to an external disk, which is not feasible for large copy operations. However, it’s no longer a problem for me, as I use Clonezilla to create full system backups, saving me time.
