If I was to do this, the 100Mb/s WAN would be saturated 24*7 - as it is we average 200Mb/s and spike to 800Mb/s without putting backup traffic over our WAN circuit. The scenario you describe is a small enough system that tape isn't necessary. > It's especially attractive if you're in an > environment that requires a lot of restores, because disk backups are > instantly available when you need them. Backups are for disaster recovery. If you have "an environment that requires a lot of restores" (ie, ID10T users who delete stuff they need) then you should look at multigenerational filesystems which allow users to haul their own rear ends out of the fire. OTOH, there's nothing like telling user that you can't restore their critical document for a few days to make them pay attention to good housekeeping practices (we have a policy of making users wait at least 48 hours. This is fully backed by management because it encourages users to take greater care of their data) ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
