# Glossary

* **Backup Destination** - backup provider or storage space holding backups on Storware Backup & Recovery node where backup files are copied to from **Staging Space**
* **Backup SLAs** - are responsible for the automation of backups of Virtual Environments or Storage instances. Backup SLA consists of the **policy** and **schedule**.
* **Cluster** - corresponds to server pools/clusters/availability zones that have been detected during inventory synchronization of **Hypervisors**
* **Hypervisors** - a list of hypervisors automatically discovered during inventory synchronization of **Hypervisor Manager** or manually added to Storware Backup & Recovery
* **Hypervisor Managers** - a list of hypervisors managers added to Storware Backup & Recovery.
* **Instances** - a list of currently known virtual machines/storage.
* **Inventory synchronization** - a task that index the contents of **Hypervisor Manager**, **Storage Provider,** or **Hypervisor** (if it's not managed by Hypervisor Manager)
* **Mounted backups** - a list of backups which has been mounted by Storware Backup & Recovery and can be browsed.
* **Node** - machine or VM with installed Storware Backup & Recovery node, its main job is to execute a backup, restore, and mounting tasks. It should have access to the **backup destination** and **staging space**.
* **Node Configuration** - contains settings for nodes to describe their behavior during tasks execution such as maximum numbers of simultaneous backup tasks, timeouts, or **backup destinations** which can be used by nodes. One node configuration can be attached to many **nodes**.
* **Policy** - allow you to group virtual machines or storage instances. Each policy can have multiple **schedules** assigned.
* **Recovery Plans** - are used to automate the DR process, so that Storware Backup & Recovery executes multiple restore operations to the target environment with preconfigured settings.
* **Schedule** - allow you to invoke specific policies periodically. This allows you to back up multiple VMs or storage instances automatically.
* **Snapshot SLAs** - are responsible for the automation of creating snapshots of Virtual Environments or storage instances. Backup SLA consists of the **policy** and **schedule**. The Instance has to be assigned to the **snapshot policy** in order to execute snapshot on demand.
* **Staging Space** - temporary space for backup files mounted on a Storware Backup & Recovery Node; default and recommended configuration is shared space on a PowerProtect DD via Boost FS.
* **Storage** - corresponds to datastores/storage repositories/storage domains that have been detected during inventory synchronization of **Hypervisors**.
* **Storage Provider** - software storage platform that provides storage instances.
