Terminology Related to Virtualization

Virtualization jobs are based on routine Block backups. These backups may be referred to in varying ways in the manuals, help, knowledge base, and white papers:

• Backup instance

• Source instance

• Recovery point

• Snapshot

• Image snapshot

The terms backup instance and source instance are more general and can refer to either file-level or block-level backups. On the other hand, recovery point, snapshot, and image snapshot refer to Block backups. Virtualization documentation generally uses the term snapshot.

You may see the term virtual controller in a virtualization wizard or documentation. This term refers to a VMware ESXi server or VMware vCenter Server.
