    vbr does not really care what the RAID configuration you have set up at either source or target. So yes, it'll work - vbr will simply copy the cluster as long as you have sufficient disk space in target nodes and target is identically configured as source (number of nodes, database name, catalog/data directories etc - see full list in the section "Configuring the Target Cluster" here).
     
    BUT a Vertica cluster (in this case, your target cluster) without any RAID has potential disk failure and performance pitfalls, see this blog post for info: https://www.vertica.com/kb/RAID-Storage-for-Vertica/Content/Hardware/RAID-Storage-for-Vertica.htm
