The TSM database is about 30 GB used of 46 GB assigned. We have a sub-rate T1 to our hot-site, with an RS-6000 installed. We are currently running mksysb images out to the system with rsync; they run to about 4.7 GB each and take about 1.2 hours. They also put enough load on the corporate internet link that we can only run them from 19:00 to 05:30 local time.
rsync, at least modern versions, have a bandwidth limiter option. We store our database copies offsite using rsync (to a Solaris box running ZFS with compression; with gzip compression enabled we're seeing compression ratios of around 8.5x). You could also consider other places to stash your database if you have a better connection to the 'net than your DR site. There are companies that provide remote rsync space, joyent comes to mind, or even amazon's s3 storage (not rsync). I don't work in the Corporate World so I have the flexibility to use those tools; YMMV. --Jim
