The underlying problem with file system backup and drives with mediocre start-stop
performance is in the "sputtering" way that Backup will send files as it encounters
them in traversing the file system. Enlarged transaction buffering will help with
this. A frontal disk storage pool, as many have suggested, also does the trick.
A more labor-intensive method would be to have a non-TSM (i.e., home-grown) tool
run through the file system to collect the names of all the candidate files and then
initiate a backup with the -FILEList option, to in effect cause streaming, eliminating
all the time gaps in candidate discovery. It's a more desperate measure, but it may
suit some installations.
