SECURELY MOVING DATA ACROSS BOUNDARIES

摘要

Data to be moved from a source system to a target system, for a set of tenants, is first identified. The data is enumerated by a first computing instance in the source system to obtain an enumeration list. Data is copied from the source system to the target system based on the enumeration list by a second computing instance. The data in the source and target systems is then enumerated by a third computing instance to determine whether any data is still to be moved and another enumeration list is generated. The data still to be moved is then moved based on the other enumeration list.

主权项

1. A computing system, comprising:
a first computing instance that has only enumeration rights to a source data container, the first computing instance enumerating the source data container to obtain a first enumeration list enumerating data in the source data container; a second computing instance that has read only access to the source data container and write access to a target data container that is remote from the source data container, is configured to copy data from the source data container to the target data container, based on the first enumeration list; and a third computing instance that compares data in the target data container to data in the source data container, after data is copied by the second computing instance, to determine whether any data is still to be moved and obtain a second enumeration list indicative of the data still to be moved, the second computing instance copying the data still to be moved from the source data container to the target data container, based on the second enumeration list.
