The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Our Backups take a long time!

Asked by agateman in Backup Exec, Removable Backup Media, Computer Servers

Tags: Symantec, Backup Exec, 11D, Dell, Powervault, 124T, SCSI attached to Dell 1950

Hi,  We have an EMC CX3-40 SAN with VMWARE ESX and windows 2003 virtual servers running.

Using a DELL 1950 running Backup EXEC we backup DISK to DISK (via network) to a LUN attached.  Then from that backup on the LUN we COPY to Tape.

My problem is that to backup 580 GB of Data with 50GB of exchange (also virtualised) it takes nearly 20 hours by them time it is saved and verified on the LTO 3  400/800

Does anyone know what real speeds for network and disk to tape I should be getting?

We have a managed layer 3 full gigabit non-blocking infrastructre using Dell Powerconnect 6224.

The ESX server each have 4 NICs teamed for these virtual machines and the servers are highly underutilised,  all VMs and other DATA is on quality and quick LUNs on the SAN.



Also I noticed that we were running out of tape storage on a single 400/800 tape for full data backup, so I've just bought an additional HP MSL6030 30x1 LTO-3 tape library.  Unforutnately it is also a SCSI device and not fibre (just like my current DELL Powervault 124T 8x1 autoloader).

What I want to know is, would I be able to simply daisy chain these two devices via SCSI and then be able to use both of them simultaneously with new backup configurations in Backup EXEC?  The Dell is really a rebadge IBM library.

Thanks...I'd appreciate any help.
