BRU or Retrospect

I have been using Retrospect 6.1 on my xserves, running 10.5.x I have had nothing but issues with it on my intel xserves. I have had resort to mounting the shares via AFP, and backing them up from there. I have a G5 as my tape server connected to a Tandberg Data Magnum 224 LTO-4 conected via Fiber Channel. 3 G5 xserves running 10.5.x 1 G4 xserve running 10.4.11.x 1 intel xserve 10.5.x 1 g5 tower running xserve 10.5.x 1 intel tower running xserve 10.5.x I was wondering if any one else is using BRU, and if they have had better results with that?
