Cloning of a system

Cloning a source system to a target system of a multiple system landscape. A depot is created in an archive by the source system. The depot is assigned a creator ID identifying the source system. One or more data packages are offloaded from the source system to the depot. For each of the data packages, a record is written to an internal control structure of the source system with a package ID and a depot ID. The source system is cloned to the target system. The target system in the form of a physical replicate of the source system is provided with read-access to the archive, which is restricted to data packages for which the cloned internal control structure includes records with data package IDs identifying the data packages and depot IDs identifying the depots including the data packages.
