Hi,
I'm looking for some guidance/ technical assistance in implementing Symantec Backup Appliance 5230 within our backup environment.
Current configuration
Master Server: VM (RHEL 6)
Media Servers: Total of 4 physical media servers (2 in production and 2 in DR site)
Total Front End Terabyte (FETB): 80 Terabytes
Question #1:
If we replace all the physical media servers and replace it with Symantec Backup Appliance 5230, can we make do with two Backup Applince (Having one appliance in Production and the other in DR site)? Is this sufficient for us to be covered in a fail-over event (e.g. If the production backup appliance goes offline, how can the DR backup appliance be promoted as the Master server and how quickly can the fail-over happen)?
Also, if the production backup appliance goes offline and assuming that the DR site backup appliance resumes the role as the Master/Media server, can it still read data off the disk residing within production environment (assuming that the network connectivity is still available in prod)? Or is the storage on the backup appliance totally dependent on the appliance header to be online in order to function?
Question #2:
How much initial storage should we purchase/ allocate? Assuming that we need to protect an initial total of 80 TB of data. Is there a simple method on calculating/forecasting an approximation on the total storage require over a period of x number of years?
Any information/ guidance is much appreciated.
Thank you.
