You are correct. Inactive versions will expire per management class
criteria. The active versions will stay around forever (*). The reason for
this is as you stated: TSM errs on the side of caution since it has no
knowledge of the status of the file system.

(*) ... at least until another incremental backup is performed for that
file system, a client node with BACKDELETE=YES deletes the backups, or a
TSM administrator deletes the file space)

Others can correct me if I am wrong.  Extra versions (inactive) are still
controlled by the management class.  The final active versions are kept
forever.  TSM does not know if they were deleted or the filespace went bad
for some reason.  Thus one has to hand delete them from TSM if they are
not
needed.  The only thing I am not 100% sure of is the inactive versions.

Can anyone tell me what the affect is if a filespace no longer exists?
Lets
say either a drive D on a Windows server or /cost1 is no longer on a unix
client. The filespace is no longer on the new client with the same name so
it hasn't been touched in say 180 days. What is really there? Does the
management class settings have any affect on it?
