Can someone please help me out on how to change this to make a tar file of a user home folder on the Raspberry and move it to my MAC desktop
ssh pi@xxxx "sudo dd if=/dev/mmcblk0 bs=1M | gzip -" | dd of=~/Desktop/pibackup.gz

From the MAC start a ssh session. I assume
sudo on the RasPi is not asking for a password.
ssh pi@xxxx sudo tar -czf - -V "Backup of the home folder from myuser" -C /home/myuser/ ./ | dd of=~/Desktop/myuser_backup.tar.gz bs=1M
The options for tar mean:
-c create a tar archive,
z create a gziped archive.
f is the archive name, here with
- it is send to standard output so it can be piped to
dd on the MAC,
-V is a description stored in the archive,
-C is the directory to start with the backup,
./ is the directory with subdirectories to backup.
This gziped tar archive is piped to
dd on the MAC and its output file is specfied with
bs=1M is to increase the block size to 1 megabyte for transfer over the network to increase performance.
