nice -n 19 ionice -c 3 rsync -a -x -AHX -S --numeric-ids --del_ete(-after) -v -P --stats -h -y 

        -a, --archive               archive mode; equals -rlptgoD (no -H,-A,-X)
        [
        -r, --recursive             recurse into directories
        -l, --links                 copy symlinks as symlinks
        -p, --perms                 preserve permissions
        -t, --times                 preserve modification times
        -g, --group                 preserve group
        -o, --owner                 preserve owner (super-user only)
        -D                          same as --devices --specials
            --devices               preserve device files (super-user only)
            --specials              preserve special files
        ]
        
        -x, --one-file-system       don't cross filesystem boundaries
        
        -A, --acls                  preserve ACLs (implies -p)
        -H, --hard-links            preserve hard links
        -X, --xattrs                preserve extended attributes

        -S, --sparse                handle sparse files efficiently

            --numeric-ids           don't map uid/gid values by user/group name

            --delete                delete extraneous files from dest dirs (is --delete-during)
            --delete-before         receiver deletes before xfer, not during
            --delete-during         receiver deletes during the transfer
            --delete-delay          find deletions during, delete after
            --delete-after          receiver deletes after transfer, not during
            Note: all (except --delete / --delete-during) disable incremental file list and therefore need more memory

eventuell praktisch:
        -v, --verbose               increase verbosity
        -P                          same as --partial --progress
        [
            --partial               keep partially transferred files
            --progress              show progress during transfer
        ]
            --stats                 give some file-transfer stats
        -h, --human-readable        output numbers in a human-readable format
        -y, --fuzzy                 find similar file for basis if no dest file [delete-after sollte hier genutzt werden]
        
        -c, --checksum              skip based on checksum, not mod-time & size
        
            --delete-excluded       also delete excluded files from dest dirs

        -z, --compress              compress file data during the transfer [besser: ssh Kompression nutzen]

        -i, --itemize-changes       output a change-summary for all updates
            --bwlimit=KBPS          limit I/O bandwidth; KBytes per second
