Use tee(1):
Code:
# tar czvf backup.tar /home 2>&1 | tee -a log.txt

The 2>&1 redirects stderr to stdout so that the error messages go into the log file also, tee sends its input to the console/terminal as well as sending it to the log file, the "-a" appends to the file (equivalent to >>), if you really want to overwrite the log file each time (like >) then remove the "-a".
