The previous version used $$ for variable expansion which doesn't work in this context. Changed to single $ for proper shell variable expansion in the database backup command.

The command was using incorrect quote escaping which could cause issues with variable expansion and file deletion. Fixed by using single quotes for the outer string and proper escaping for date command substitution.
