Data collection
Importing
Manual addition
Once hosts and backup servers are in the Portal, you can organize them into Host Groups to serve a number of functions:
Organize hosts to create groupings relevant to your business.
Control report scope to tailor report output to include only a specific subset of host data. In the Portal, this data filtering capability is known as the report scope.
Limit user access to hosts and data by assigning a home host group to a user, limiting access to only the data in that group and its sub-groups. This also serves as a security mechanism. Domains are also used to limit access.
