Best practices for setting up Dell VTL Container or NetVault Backup native virtual tape library (nVTL)
6
Pros and Cons for each VTL Technique
While Virtual Tape Libraries can be implemented in my ways on the Dell DR Appliance
and Dell NetVault Backup software solution some are better suited to deployment in
diering environments. In the sections below specific features that impact the decision
process regarding which VTL technique users should implement is clearly defined in a
Pro vs Con format.
Dell DR VTL Container
Pro – Dell recommended VTL technology
Pro – Native VTL technology for the Dell DR Appliance
Pro – Much easier to Setup, Configure, and Maintain than nVTL technology
Pro – Supports backup of NetVault NDMP data
Pro – Supports inline data deduplication
Pro – Does not rely on 3rd party transfer technology like CIFS or NFS
Con – Does not currently support DR VTL Container Replication
Dell NetVault Backup nVTL
Pro - Support DR VTL Container Replication
Pro – Supports backup of NetVault NDMP data
Pro – Supports inline data deduplication
Con – More dicult to Setup, Configure, and Maintain than DR VTL
Container technology
Con – Relies on 3rd party transfer technology like CIFS or NFS
Con – Requires the use of space reclamation scripts
