Best practices for creating an AFTD Device
Hi all,
I am configuring a new AFTD devices into our Networker enviroment and we have some questions about these kind of devices.
The AFTD devices will be created on a mounted CIFS share into our Networker Windows 2008 server.
I have read the administrator guide of 7.6.5.x version and we have some doubts:
Which are the best practices for AFTD backups?, for example:
I need to do a backup of about 30TB of data from multiple clients/type of data, so should be recomended to create separate AFTD's devices or is best to create a single one AFTD device?
On the other hand, we have seen at the admin guide (Recover savesets by using AFTD concurrent operations) that is not possible to execute multiple concurrent recoveries/restores from an AFTD device:
- For file recoveries is needed to execute the recover coommand (winworker not available).
- For non-filerecoveries: such NMO or NMDA modules is also not supported to execute 2 recoveries at the same time.
Our question is: if I create different AFTD's devices, I could separate these devices for each pool/kind of data or clients, so I could skip the limitation, no?.
This could be a trick to skip the limitation such as I understand, I could execute more than one recovery process against a different AFTD device, no?
* Summarize:
1 AFTD device --> 2 recoveries at the same time not supported or with some limitations.
3 AFTD devices --> > 1 recovery proceess could be executed, one recovery per AFTD device, is this ok?.
Best regards,
Alexander Glez.

You should create multiple devices - say 4-6. Read capabilities depend on NW version and what is on backend. For example in NW8 you can have multiple reads and with NW7 not (NW7, at least latest releases, do support multiple reads for DD devices though).
