Each volume consists of a scalableobject store with deduplication. The scalable object store behaves as a records-based file system, where the unit ofstorage allocation is a fixed-sized data block called a record. This architecture allows you to configure block-sizedsupport for compression and deduplication. Rollup operations are reduced to metadata operations from disk intensiveoperations because the rollup no longer moves data but only moves the records.The DVM can combine a set of object stores into a volume and they can be expanded by creating additional file systems.The object store files are pre-allocated and can be added on demand as storage requirements change. It is possible tocreate up to 255 independent repositories on a single AppAssure 5 Core and to further increase the size of a repositoryby adding new file extents. An extended repository may contain up to 4,096 extents that span across different storagetechnologies. The maximum size of a repository is 32 Exabytes. Multiple repositories can exist on a single core.True Global DeduplicationTrue Global Deduplication is an effective method of reducing backup storage needs by eliminating redundant orduplicate data. Deduplication is effective because only a unique instance of the data across multiple backups is storedin the repository. The redundant data is stored, but not physically; it is simply replaced with a pointer to the a uniquedata instance in the repository. Conventional backup applications have been performing repetitive full backups everyweek, but AppAssure performs incremental block-level backups of the machines forever. This incremental foreverapproach in tandem with data deduplication helps to drastically reduce the total quantity of data committed to the disk.The typical disk layout of a server consists of the operating system, application, and data. In most environments, theadministrators often use a common flavor of the server and desktop operating across multiple systems for effectivedeployment and management. When backup is performed at the block level across multiple machines at the same time,it provides a more granular view of what is in the backup and what is not, irrespective of the source. This data includesthe operating system, the applications, and the application data across the environment.16
