Understanding repositories
A repository is a central location in which backup snapshot data captured from your protected workstations and
server is stored and managed. Data is saved to a repository in the form of recovery points.
A repository can reside on different storage technologies, including Storage Area Network (SAN), Direct Attached
Storage (DAS), or Network Attached Storage (NAS).
NOTE:
Store repositories for Rapid Recovery Core on primary storage devices. Speed for the storage
volume is the most critical factor. Archival storage devices such as Data Domain are not supported due
to performance limitations. Similarly, do not store repositories on NAS filers that tier to the cloud, as these
devices tend to have performance limitations when used as primary storage.
DAS offers the highest data bandwidth and fastest access rate, and is easy to implement. For optimum
, Repository Options: Direct Attached Storage, Storage Area Network or Network
Attached Storage.
The storage location for any repository should always be in a subdirectory that you specify (for example,
E:
\Repository
), never in the root of a volume (for example,
E:\
).
The Rapid Recovery repository format uses Deduplication Volume Manager (DVM). DVM repositories support
multiple volumes, up to 255 repositories on a single Core, and the use of extents. You can create DVM
repositories on machines with Windows operating systems only. You can use this repository type when using new
Rapid Recovery installations. You can specify the size of a DVM repository upon creation, and can add extents
later.
