Embodiments operate a multi-tenant cloud system. At a first data center, embodiments authenticate a first client and store resources that correspond to the first client, the first data center in communication with a second data center that is configured to authenticate the first client. Embodiments divide the resources into base data and regular data, where the base data is a minimum data needed to allow the resources to be available to the first client at the second data center. Embodiments store the base data on a cloud storage in a base data export file and store the regular data on the cloud storage in a regular data export file. Embodiments export the base data export file to the second data center and when the exporting the base data export file has completed, exports the regular data export file to the second data center.
