I have some questions regarding a large scale deployment using Veritas Backup Exec. Let me try and explain our design first.
We are proposing a 3 tiered architecture in our design with Central Administration server (CAS) at tier 1 (Head quarter), managed backup exec servers at tier 2 (city main-office), and agents at tier 3.
Each Managed backup exec server site (City Main Office) will have it's own Local network + some sub-sites (sub offices within the same city but far away) connected via a Poor bandwidth WAN connection as shown below-
I have a few questions regarding this setup due to the WAN bandwidth constraints-
1) Can a local network attached NAS at sub-site 'n' be used to store backup data from Agent 'n'?
2) Can a locally agent 'n' attached hard drive or iSCSI drive be used to store backup data from that particular agent 'n' ?
3) If I choose to process the backup data on the server instead of the agent (Advanced disk-based backup feature) using the Off-host backup option, will the entire data be sent to server 1st via the network for processing, and then sent to whatever configured storage node?
For BE, the data will always flow from the source to the BE Server and then to the destination. The only exception is client-side dedup in which case the data goes from the source to the dedup folder directly.
Off-host backups is quite restrictive, so read its requirements carefully.
Thank you. I guess we'll have to go back to the drawing board now.
btw, is there any way to configure an agent to send the processed backup data directly to a locally attached storage instead of the backup server?
