Cloud Storage is increasingly being used for low retrieval data sets or as the Disaster Recovery (DR) copy of data. Solutions (such as those built around Amazon S3, Amazon VTL or OpenStack APIs) have rapidly grown as users review the cost of offsite storage. Capital Expenditure (CAPEX) is replaced with Operating Expenditure (OPEX) as the user no longer owns the hardware that stores their data. The Cloud provider is now responsible for securing the data and migrating it over time as the original storage device expires.
Typically archive data is collected at an “Edge” server, which presents itself as a network share. QStar Archive Manager is a good example of Edge server software and can be used on a virtual or physical server. Periodically data is sent to the remote store using a dedicated link or wide area network technology. With the correct connection speed, data can be retrieved as if it was still on the users network.

A drawback in using cloud storage can be the cost of uploading and downloading data. Many organizations are not proficient at analyzing what they store in their archive (preferring to store all rather than delete data that they made need later).
As part of a 3-2-1 Archive, cloud storage can play an important role. Cloud offers a convenient and simple method to archive data that is infrequently accessed and provides a DR store for organizations that do not have a second remote site. Using QStar Archive Replicator software, cloud storage can be paired with any local archive storage solution: tape, optical, RDX, RAID or object storage.
