rsync help the gramma

[Dazed_75]

One thing I might point out though is that you (Betty) said you did the
backup about once a month and your example shows rsyncing to a directory
named for the month (October).  That's fine but some people use rsync to
update a single backup destination so they don't keep each backup
separately.  You choice which best suits you, but I thought it worth
mentioning.
