To delete a fileset family from the Backup Database, do the following:
1. Verify that you are included in the appropriate administrative lists. If necessary, issue the bos lsadmin command to check.
2. Issue the bak rmftfamily command to delete each fileset family that you no longer need. It is not necessary to delete the fileset entries in each fileset family first; they are deleted automatically when the family is removed.
$ bak rmftfamily -family fileset_family_name...
