Direcories may expire, but files never end up in "limbo". Examine the
BACKUPS table: each object is fully identified by filespace and its
full path, which obviously includes its containing directory. Backing
up a directory, as an object, is usually rather meaningless in a Unix
environment as such directories have no supplementary info. In a
Windows environment, there is a lot of supplementary info, which is why
Windows directories end up in storage pools while traditional Unix
directories are simply identified in the TSM database.
In a restoral, surrogate replacement directory info is planted where
either the dir is not in the TSM db, or has not yet been encountered in
Restore Order. The absence of a directory in TSM is problematic in GUI
restorals, where the GUI wants to present each dir as you navigate down
the path tree: this can cause the GUI to go no further. TSM wants
directories to exist at least as long as contained objects, for a
reason.

Hi all TSMers
Running TSM 5.1.6.2 on Solaris and have a question regarding the
different
way that directories and files are dealt with. I have always been used
to
excluding files, directories, file spaces etc and also including them
with
different management classes should the need arise for something other
than
our standard retention settings. However, I have only just learnt
about the
dirmc setting and this has lead me to believe that we probably a few
million entries in our TSM db for directories that are no longer
relevant (
the deleted files having been expired after 60 days but the directories
having been bound to one of our higher retention man classes ). So
here is
my question.
Lets say I have a retention policy on a dir that states that the only
copy
of a file (after deletion), should be kept in backup for 365 days but
that
I have a dirmc setting in the clients dsm.sys files that will expire
all
deleted directories after just 60 days, how does TSM handle this? What
happens re expiration after 60 days? Do the directories get expired
and the
files just end up in some kind of limbo?
Many thanks in advance
