    There is another way, and that is to use options like --link-dest to
    create separate point-in-time snapshots with deduping to save space.

    I don't understand the instructions for link-dest either in the "rsync
    --help" command line, or in man.

    First backup:

    rsync ®various-options¯ ®src-dir¯ ®backup-dir-1¯

    Second backup:

    rsync ®various-options¯ --link-dest=®backup-dir-1¯ ®src-dir¯
    ®backup-dir-2¯

    Now you have backups from two points in time. For restore purposes, each
    one looks like a full backup, even though the second one was created as
    an incremental backup. The --link-dest option means that files that were unchanged share a single copy that is hard-linked into both places,
    saving both storage space and network traffic (if the backup is being
    done over a network).

    You can continue this sequence to save backups from as many points in
    time as you like. To get rid of old backups, just do

    rm -rf ®backup-dir-1¯

    etc.

    Interesting, and now at least I know what "hard link" means. But I don't actually see how it helps. Both this method and the ordinary method still
    have to make a full backup copy of every new file in the live system, and neither have to make copies of files in the live system that are *not*
    new.

    Moreover, both methods retain copies of files that have been moved or
    deleted in the live system since the last backup, so the backup archive
    gets cluttered up with these orphan files. You either have to delete them
    with "--delete", or accept this clutter will continue to grow until you
    decide to make a brand new backup from scratch.

    This method does an incremental backup, saving both drive space and
    network traffic. The hard links make it look like a full backup for
    restoration purposes.
