Files are recovered from TSM by using the dsmj (GUI) or dsmc (command line) programs. If you backed up files from a flora Centos public machine, then you can also restore the file from a florathat same host. Users may recover any file owned by their account using either interface, though the graphical interface may be easier to understand. See the TSM Restore Web page How-to article "Restoring files using TSM" for instructions on restoring your files. To request the restoration of files you do not own or that were backed up directly from an NFS server (as opposed to the client you login to), send email (with an explanation) to unix-admin. Include an explanation, the full path to the file, and from what point in time you need a restore.
TSM is an incremental backup system. It backs up only the files that changed since the last backup, and maintains information on the state of the client file system. It is possible to restore the file system to the last backup state, and to restore some older versions of deleted files. TSM is not configured to restore the file system to the state it had at a specific point in time, i.e., it may not be possible to restore a directory to the way it looked 4 weeks ago at 12pm or any other particular day or time. Such a policy would use significantly more tape space since the backup server would be forced to keep a copy of every file version going back to that date.
