I have some general questions regarding NetBackup's Disk Staging Storage
Unit (DSSU) and Virtual Tape Library (VTL):

 

1.      If DSSU gives you the ability to write to disk and at a later time,
migrate the backups to tape, what is the advantage of using Virtual Tape
Library?
2.      If I was to implement VTL, how will this impact the license cost
from Veritas?  Would cost go down, up, or stay the same? 
3.      Is one method better then the other (DSSU vs VTL)?

 

Thanks for you comments,

Ken
