Virtual disk tool "VVAULT" which was carried in new model "LSV-5S4CW2" of Logitec NAS series as standard equipment. We can use Logitec NAS as more convenient storage by using this tool including "unification of the volume" "data shift from old NAS" "replication".
For example, we want to consider backup of NAS oneself when we use NAS in file server. How you backed up large-capacity NAS was seductive point in such a case. Even in such a case we become able to build back-up system cheaply if we use "VVAULT". We see case backing up NAS of 8TB class for example here.
When we introduce new NAS, shift of data of old NAS is seed of trouble. Problem such as not being able to do it by the use is over new NAS until backup is completed. However, access is possible for data of NAS which is old via new NAS if we use "VVAULT" if we make even setting first. Furthermore, shift of data completes as backup goes in background at the same time in new NAS even if we remain silent.
Replication means that we make replica (reproduction). Data are written in at another NAS automatically when we write in data at one NAS. In this way, it is substitute of NAS where we just change setting of another NAS even if malfunction occurs in one NAS, and malfunction occurred. It is representative solution for BCP(Business Continue Plan).
