Hi
Also, at least earlier, Legato used a sequential file to handle
information about clients, tapes, files and so on... TSM uses a DB/2
database, which is much more efficent than using a sequential file.
Also, when having larger environments, the sequential file becomes a
bottleneck, which can reduce performance in a noticable way.

Hi,
I have limitted experience with Legato, but it too, like TSM, puts all
backups
of one node, both full and incremental, in one storagepool, even does full
and
incremantal on the same tape if possible...
