Can I keep my Dat72 and LTO3 connected at the same time?

Hi Folks

I am preparing to upgrade from Arcserve 11.1 to 12.5.

I have been using a DAT72 drive on our server but have purchased a Quantum LTO3 to use for future backups after the upgrade. I have done this because the number of DAT72 tapes used has reached 8 for a full backup and it takes 24hrs to complete a full backup of c. 315GB.

What I would like to know is can I chain the DAT72 and the LTO3 together? So I would have: the server -> LTO3 -> DAT72 -> terminated

This way I can (hopefully) restore data from the (redundant) DAT72 tapes if required.

What I don't know is if this will affect the speed at which data can be written to the LTO3 tapes. The whole point of purchasing the LTO3 is so that I can do a complete backup overnight without the need to manually change the tapes.

Are there anything else I need to consider? I don't really know much about this. I've only had one device attached to the SCSI card on the server.

Any help will be gratefully received.

Thanks

Mark

it will probably be better to have them on separate controllers.

Hi, David

Thank you for that. If we need to restore data then I will remove the LTO and connect the DAT72 in its place as there is just one controller in the server.

Thanks again.

Cheers!
