space, it is recommended to specify the size of the Time Machine folder (for example, twice

or three times the storage capacity on your PC) in the data of external storage device to NAS with USB CopyNAS will recognize and conduct a copy task when a USB device is connected. Once the task

active server handles all data requests and services and continuously replicates all data to

the passive server. This collaboration allows the passive server to automatically take over

in case of any unexpected incidents, so that services and applications can be recovered

within minutes.9
