A common ask when making a change in CA Service Desk Manager (CA SDM) is to backup a given file. There are various approaches to this task. A frequent tactic would be to copy/paste the same file in place, creating a duplicate of the same file in the same location. However, this introduces the possibility of a file conflict during later operations, such as pdm_publish or pdm_configure, and possible corruption of the CA SDM environment.
The recommended approach when backing up an individual file before directly manipulating it is to copy a given file that is being backed up and pasting it in a location outside of the CA Service Desk Manager directory.
An approach that is frequently used, creating a duplicate file in the same location with either an alternate extension or a string to identify it as a copy (i.e. "Copy of wsp_schema.sch") is not an advisable method.
The reason is that there are components in CA SDM that may process a duplicate file in its operations, causing a conflict of existing content that should take precedence.
