Deduplication appliance or Backup Exec Deduplication Option
I have to design a backup solution with deduplication. All my Virtual Servers that I have to backup, have 6.5TB.
Also deduplicate the backups, I need reduce the backups windows time. I have two option to choose and I need help:
1) Put an appliance (DELL DR4100, w/ 4x1GbE, Nearland SAS 7.K RPM) that deduplicate the backups.
2) Put an storage (with 10K RPM Disks and FC 8Gbps) and deduplicate in the BackupExec server (with Deduplication Option).
I have similar costs in both option, but I need reduce the window time of backup. What is the best option?
How much reduces space with the Deduplication Option? (10:1, 5:1, etc)
In the case of deduplication appliance, What is the way of the data? "From the client to appliance" or "from the client, arrive to BackupExec Server and it send to deduplication appliance".
