We just moved to Data Domain appliances. They are fantastic. We do disk to disk in our data center and then it replicates automatically to a second box off-site. Everything is deduped so the traffic to the second site is very small. Tapes are only used for stuff we have to keep around long term (~ 7 years).

I do not have enough space on hand to handle back up data very far back if I went to disk only. My off site link is to a colo and is only 10MB, so it would be difficult to handle.

I am of the opinion that true "backups" should be done to disk, "archives" should be done to tape. For years Bus and archives have really been one and the same due to technology's inability to truly differentiate them, but that isn't the case anymore.

Luke had the best answer, a full then differentials until the next full backup. That way you only need two tapes to ensure that you have a complete backup set. John H.

We have been small enough to do full back ups daily for some time, but now face time issues with that and need to move to a tiered option. Is F-I-I-I-I reasonable anymore or is it too risky? I do not want to be stuck with a bad full back up in an emergency. -- http://www.otbdesign.com <http://www.otbdesign.com/> http://www.linkedin.com/in/mqcarpenter ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~ ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~ -- http://www.otbdesign.com http://www.linkedin.com/in/mqcarpenter ~ Ninja Email Security with Cloudmark Spam Engine Gets Image Spam ~ ~ http://www.sunbeltsoftware.com/Ninja ~
