This would be a hard thing to recommend...here are a few reasons why....just off the top of my head...you need more specifics about what the backup system is trying to accomplish. The correct solutions would depend on where the 200 GB/Week is from. * Is the 200 GB / week at one location? Distributed? - One geographic Location, but backups come from 10 or so servers. WE are using Backup Exec with the agent accelerator. * Is it all on a SAN? - There is no SAN. * Is it distributed on various servers? (ie. A few dozen servers with RAID1 and RAID5). -Distributed amongst 10+ server all with RAID1 for OS and RAID5 for the Data. * Is your network 100MB? -Network is 100MB FullDuplex with 1gig Copper backbones between switch layers. * Where are the bottlenecks in the current backup system? -Bottlenecks are in amount of data we can backup, since we are using a single tape backup right now. * What is current system, and what are your aiming to upgrade to? We are currently using a DLT4000 but are looking to move into a faster technology. Also, the solution will depend on other matters like: * What is your retention policy? -We store full backups each week and monthly, and recycle the daily tapes every 2 weeks. Policy dictates one days loss is acceptable. * Is there a level of service that you are trying to achieve? (eg. be able to restore a SQL or Exchange mail system with XXX number of minutes, hours, or days) -One day. Thanks for the input Leonard. What I am really asking is what new technology ie. LTO, Super DLT, AIT is backing up data faster across a network. As for the rest of the research I can do that on my own, which I have begun to already. I know what these manufacturers are saying there hardware can do, but what they say it can do and what it actually does are two different things, thanks again. -TOny Leonard > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Anthony L. > Sollars > Sent: March 29, 2002 1:19 PM > To: NT 2000 Discussions > Subject: Backup HArdware Advice. > > > > I am in the research of a complete re-design of our media > backup system.
