physical tapes has its down sides—a high level of manual intervention, tape tracking requirements,
etc. The physical transfer of tapes off-site is not very automated.
In addition, one of the pain points for many companies large and small is protecting data in remote
offices. Untrained IT staff manage a daily backup process involving changing of physical tapes,
and the process is prone to human error.
HP replication, available on its VLS and D2D systems, now offers the solution to both these problems.
You can replicate local backup data (virtual cartridges) between sites in a reliable, automated
manner at a fraction of the costs previously required when using high bandwidth links or in some
cases physical tape offsiting.
Consider the "Before" and "After" scenarios detailed below.
