Partial backup failure with 'Snapshot encountered error 156'

There can be a partial backup failure when the NetBackup client and the alternate client that are specified in the policy are located on the same host. The off-host backup functionality ideally shifts the load of backup processing onto an alternate client. The alternate client sends the client's data to the storage device.

When both the client and alternate client are on the same host, the off-host backup purpose is lost. The client load is increases and backups fail.
