replication and tape backup
If I use replication to make a copy of data at a DR site
how do I create a tape backup off of that for long-term retention? Short-lived snaps are no problem, they only live on disk but once every few months I want to write a tape to capture that point in time for longer retention. If the DR site only has replicated LUNs how do I do tape backup for the long-term? To say it another way if I have N different types of clients using replicated SAN storage do I have to buy N more clients for the DR site to mount those volumes as filesystems in order to run Netbackup? |

The issue you will have to deal with is the number of different file
system types that exist at the DR site. A Windows 2003 system should be able to handle LUNs from any earlier version of windows. The same rule would apply to a Linux environment as well. If you have a mix of operating systems but they are all running on a x86 platform then you could consider using a product like VMWare to create a virtual machine for each OS. If, however, you have clients with different architectures such as Windows clients and Apple clients then you will likely need seperate physical boxes to back up such an environment.

Veritas NetBackup includes in its base product disk staging. You could
create 2 copies from disk or "clones" wrote in message oups.com... If I use replication to make a copy of data at a DR site how do I create a tape backup off of that for long-term retention?
