correction the backup is complete in /media/home/. but not loading onto the USB stick.

could it be that the usb stick is vfat although aptik has transferred several back up files to the usb stick. or my coding errors?

can you give me an idea of the corrected code there a few mail directories I wish to save.would saving these be sufficient to transfer contents to new reload? I like to use rsync for backups. cp -a is good for a file or two. rsync is way better to backup up directories. And rsync works well for restoring from backups.;
Here is a simple example
First I do a dry run to see what will happen, especially important when using --delete. rsync -havn /home/me/ /backup/home/me/ --delete --exclude=*.iso
Then get rid of the n option to actually do it. rsync -hav /home/me/ /backup/home/me/ --delete --exclude=*.iso
And for extra credit, here is a more complex example from a backup script file.
rsync -hav $task $dest$task --backup --backup-dir=$bkupdest$task --exclude-from=$whatnottobackup --delete --one-file-system --numeric-ids --delete-excluded
Where $task is something like /etc/ /home/me/ /var/www/
$dest$task is something like /backup/hostname/current/etc/
$bkupdest$task is something like /backup/hostname/2015-05/16/etc/
$whatnottobackup is a file that includes things like #exclude.txt file *.SV$ *.bak *.iso /var/cache/apt/archives Trash/ trash/
