Abstract: A cloud storage gateway device can be used to deduplicate data across different namespaces while complying with SLOs that govern data of the different namespaces. A cloud storage gateway device can use multiple fingerprint indexes to comply with different SLOs. Each fingerprint index corresponds to a different SLO. Thus, the cloud storage gateway device deduplicates data against other data governed by a same SLO. Assuming an SLO aligns or indicates a cloud storage target, the cloud storage gateway device will deduplicate data against other data that will eventually migrate from the device to a same cloud storage target. The cloud storage gateway device ensures satisfaction of the governing SLO(s) from receipt of data, through deduplication, to the migration of the data to a cloud storage target.
