I guess you won't know until you try it.
Is the concern that the homedirs are all on one big server, and that you
therefore have a single 10TB dataset to scan for changes? If that's the
case, one thing that other users have reported good results with is
partitioning the homedirs into groups, so that you end up with say ten
1TB groups or even twenty 500GB groups, and back the groups up as
separate jobs that run in parallel. This can give you a big speedup for
incrementals, which typically spend most of their time scanning for
changed files and relatively little actually backing up the changed files.
