reducing size of SharePoint replication

[cookie-monster]

My company has increased it's use of SharePoint over the last 6 months. We've got about 160gb of data to backup. I do a disk backup every day and then use that as the source to replicate the server offsite. The time it takes to replicate this server has grown and is hitting my time-window. When I checked the amount of data I'm replicating it's about 80-90gb per day. Seems like a lot of change for a 160gb database?

I'm looking for advice on either reducing the amount of data-change or a strategy to replicate this SharePoint server more effectively.

Thanks!

Hi Derek, what kind of link do you have to the remote site and what are the bottleneck stats for the replication job?
