DFS is a great way to provide real or near real time replication, and you
can do it between Sites over WAN links. However, like any other network
transfer, the performance you get will be greatly affected by bandwidth and
the volume of other network traffic. After confirming your T1 hardware
speed/configuration, consider:
1. Assuming this is a single Active Directory domain/forest, how is it
implemented over this link. If you do not have a domain controller in
Houston and you have not configured Sites, you may be sending an
unnecessarily large volume of traffic over this link. The conventional way
to control this is with Site configuration - See:

2. Forget about transferring 50 GB of data over this link. Every Sunday I
run a full backup on 3 servers to a network drive on a LAN at 100 mbps. The
backups total about 40 GB and the process takes 2 to 2 1/2 hours. At T1
speeds it would take 166 hours. Also even at LAN speeds any machine
transferring a very large file or a very large number of files is going to
slow down during the transfer process.
Assuming that the 50 GB has built up over time and the daily volume of new
or changed files is much less, you still need to consider the possibility
that the daily volume is simply too large to give adequate performance over
this link, especially if the link is being shared for other network needs.
