Table: CDP terminology
Term | Explanation |
|---|---|
CDP gateway | CDP configured media server. |
VAIO | The VMware framework consists of vSphere APIs for I/O filtering. This framework lets CDP run filters on ESXi servers and intercept I/O requests from guest operating systems to a virtual disk. |
Full sync | NetBackup retrieves a VM's entire data from the ESXi. |
OST | Open Storage Technology is a STU supported by NetBackup. |
MSDP | Media server deduplication storage pool is a NetBackup dedupe technology engine to optimize backup storage. |
Storage policy | A VMware vSphere feature that enables storage profile creation by administrators. This means that the VMs do not need to be configured separately, and management may be automated. |
VIB | vSphere Installation Bundle. At a conceptual level, a VIB is similar to a tarball or compressed archive. It is a collection of files packaged into a single archive to facilitate distribution. |
nbcctd | CDP service (daemon) running on the CDP gateway. |
Staging area | A storage location on the CDP gateway where NetBackup temporarily stores I/Os received from the ESXi. |
Storage quota | Allocated limited storage size for VMs using CDP protection. |
Reserved quota | Shared storage between all VMs registered to a CDP gateway. |
VADP | VMware VADP is a VMware vStorage API that backs up and restores vSphere virtual machines (VMs). |
