Hi,
I have a number of netbackup questions and as you will notice the reccurring "theme" in those questions is around virtulisation of media servers as well as multi-tenancy/security.
1.What is Symantec’s recommendation on Virtual vs. Physical media servers in relation to scalability and performance. Comparing a media server VM and a physical media server with similar CPU/mem etc should we expect similar performance? Note: I am fully aware that for tape backups we need physical.
2. We have customers with mixed physical/virtual (VMware) environments that require backup, and use VAPD to backup the virtual part. Assuming we make the choice to use media VM's rather than physical media servers to backup those virtual environments, can/should we use the same media VM’s to backup the physical environments of those customers too (note: bare metal customer servers to be backed up in our case are typically RHEL 5/6 and Windows 2008R2/2012).
3. Which of the two is preferable: to increase the number of media VM’s rather than increase the resource in each media VM when the number of clients we backup grows.
4. Can a physical media server (either RHEL6 or 2008R2/2012) be used to backup to tape via FC, and the same media server to also connect via Ethernet and backup via IP OST to a different disk-based target (EMC Data Domain for that matter).
5. Media server and multi-tenancy in relation to performance/scalability and security: If I look after a multi-tenant environment requiring backup where customers need to be kept separate, is it preferable to use a single media server (OST-based) for all customers, or would I be better off virtualising the media server and dedicating a media VM per tenant/customer? Note: the master has to be shared amongst all those customers.
Many thanks in advance.
