We used XFS for a very long time, but in the last server upgrade
switched to indexed ext3. Not because of any specific problems with XFS
but because development & bug-fixing seems/seemed to have flat-lined and
I didn't want to get stuck with what was basically an unsupported
filesystem on a critical production system. There are advantages to
being in the mainstream. :)
But I never had any performance problems with XFS, certainly not
regarding backup. Throughput was much higher than 1Mb/s [which seems
ridiculously slow, I'd suspect something else was in play].
XFS is still my favorite filesystem, with good performance, real tools,
and excellent EA support; but I can't justify using it in production
anymore. Actually I think XFS is the only filesystem with really
enterprise grade tools: with the ability to defrag, freeze, and grow on
