| Operation | Target disk Signature |
| Any restore or clone to a GPT disk | Existing signature is not changed. Or, if the target is an empty/uninitialised uninitialized disk then a new random signature will be generated for a clone operation, or if a restore creates a disk signature collision. |
| All target partitions overwritten | The signature will be the same as the source disk for an image Restore operation. |
| Source disk id present after restore (e.g. in the case of a clone) | New randomly generated signature |
| Some original target partitions remain after restore | Existing signature is not changed. |
| Target partitioning scheme different from source (e.g. source MBR, target GPT) | Existing signature is not changed, If the target is an empty/uninitialised disk uninitialized disk then a new random signature will be generated. |
| Target uninitialized, MBR source disk, target < 2TB | The signature will be the same as the source disk in the image |
