Yes it can, if it is just one filesystem you will have to manually split it
in the TSM BA configuration but this can also be done.
I am not sure if it is going to be faster than a backup via disk, that will
depend on the size and the amount of the files to be backed up I think.
How many files are there and what is your changerate on the data in amount
of files and TB's?
I am sure you know about the BA journaling feature, that could be a life
saver when you have large amounts of files and you are on a supported
filesystem & platform.
