Deciding where to run NetBackup Snapshot Manager for Cloud
You can deploy NetBackup Snapshot Manager for Cloud in the following ways:
Deploy NetBackup Snapshot Manager in a cloud and manage assets in same cloud.
Deploy NetBackup Snapshot Manager in a cloud and manage assets in multiple clouds.
Cohesity recommends that you deploy NetBackup Snapshot Manager on a cloud to protect your cloud assets. If you want to protect assets in a cloud, deploy the NetBackup Snapshot Manager host instance in the same cloud environment.
To protect cloud assets using storage arrays such as Azure Files, Azure NetApp Files, or FSx for AWS, refer to the NetBackup Snapshot Manager for Data Center Administrator's Guide.
If you install NetBackup Snapshot Manager on multiple hosts, we recommend that each NetBackup Snapshot Manager instance manage separate resources. For example, two NetBackup Snapshot Manager instances should not manage the same AWS account or the same Azure subscription. The following scenario illustrates why having two NetBackup Snapshot Manager instances managing the same resources creates problems:
NetBackup Snapshot Manager instance A and NetBackup Snapshot Manager instance B both manage the assets of the same AWS account.
On NetBackup Snapshot Manager instance A, the administrator takes a snapshot of an AWS virtual machine. The database on NetBackup Snapshot Manager instance A stores the virtual machine's metadata. This metadata includes the virtual machine's storage size and its disk configuration.
Later, on NetBackup Snapshot Manager instance B, the administrator restores the virtual machine snapshot. NetBackup Snapshot Manager instance B does not have access to the virtual machine's metadata. It restores the snapshot, but it does not know the virtual machine's specific configuration. Instead, it substitutes the default values for the storage size configuration. The result is a restored virtual machine that does not match the original.
