You can choose interactive mode, by using dsmc command, or directly start the full command: dsmc <TSM command>. Here I just explain interactive mode:

Search a file which was backup on TSM:

• Unordered List Itemfull path is required, is the file is not in your current directory (before starting dsmc)
• option -ina (inactive files), to list an old version of a file, or a deleted file. Active file is a file that was present on the server during last backup.

tsm> q ba smit.log

Restore a file which was backup on TSM:

• options: -sub (subdirectory to restore), -ina (list active and inactive versions), -pitt (point in time), -pitd (point in time date), -pick (create an interactive list of files to restore)…, check for other optins into the “help”

Usage: rest “<file or directory>” [target_dir/] [options]

tsm> dsmc rest "/Users/user1/file?.c" /Users/user2/ -sub=yes

Restore all files in the /home/mydir directory to their state as of 1:00 PM on August 17, 2002.

tsm> restore -ina -pitd=8/17/2002 -pitt=13:00:00 /home/mydir/

Restore in interactive mode, by choosing the version you want restore:

tsm> rest -pick -ina /root/smit.log /tmp/
