I had about a TB on my Vault but ultimately decided I would rather have my music on a NAS and was able to back up my Vault to a Synology NAS. I still use the Vault2 in one system as the streamer to access the NAS. In the Blue OS under folders, it offers both the NAS and the Vault2. I have added more music to the NAS since doing this backup a couple of years ago. The Synology NAS has a cloud back up function, hopefully it will never be required
