Reading Time: 2 minutes Hot-add trasport mode is a valuable solution for serveral environment, but is not necessary the fastest (see Slow speed in hot-add transport mode backup) or the best solution. But for some environments (for example VMware vSAN) it’s the recommended approach. But in VMware vSphere 6.5 and 6.7 that can be some issues using hot-add on proxy with a huge number of virtual disks. Note that this issue is resolved in ESXi 6.5 P03 and ESXi 6.7 U1.
