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
