An emergency disk is a CD, DVD, USB flash drive or USB external hard disk drive containing a standalone version of EaseUS Todo Backup 5.0 which can be booted. It can be used to restore the users' system or partitions. Once the system is booted up from the disk, users could restore the computer by EaseUS Todo Backup in this emergency disk.

Recover to dissimilar hardware

The term "clone" refers to duplicating all the contents of the source partitions/disk to the destination partitions/disk in file by file mode or in sector by sector mode, and then you can get a disk/partition which is exactly the same as the original one. Please note that the clone process will erase all the data on the destination partition/disk.
A system snapshot is the state of a system at a particular point in time. The term was coined as an analogy to that in photography. EaseUS Todo Backup monitors all the changes from the last Snapshot point had been created. This snapshot point usually takes only seconds to be created. Snapshots offer the quickest way to restore a damaged Windows system to a working state.
System partition and boot partition
Whenever a computer system is started, either from a cold boot using the power switch or a warm boot such as restarting the system from within Windows, there are certain files (for example: Ntldr) needed to boot (start) the computer. These boot files reside on the System partition. On dynamic disks, this is known as the system volume.
Once the boot files have been accessed and performed their function, the system files (the files that comprise the XP operating system) are accessed to complete the system start. The system files reside on the Boot partition. The boot partition can, but is not required, to be the same partition as the system partition.
Every track in hard disks can be subdivided into a number of sections. Each section is called a sector. Sectors are the smallest storage units on a hard drive. Each sector stores a fixed amount of user data. Typically a sector will hold 512 bytes of information.
