# Storage groups

The main screen for storage groups lists the existing groups, showing information on their free and used space. This information comes from adding the space of the related disks.

It also shows the button to _**Create a new storage group**_.

When creating or editing a storage group, the only data field to set up is the name of the group. Disk assignment is done at the moment of disk registry.

Once a disk is assigned to a group, this cannot be changed.

From the preservation point of view, a storage group is going to represent a specific repository, and it is convenient that all disks associated to a storage group have common characteristics as for the risks they run. That is to say, that they are all in the same geographical location, are of the same kind, same technology, etc.
