Large tar file taking huge disk space in ext3 file system
I am trying to backup some of my data by tarring in to another hard drive (I am in fact compressing them using bzip2 later -- but that's not relevent to this question).
My original directory tree has taken (du -sk <directory>) about 1.9GB. So, I was surprised to see that the tar file has taken 3.3GB.
Command used was find <source directory> |tar -cv <tar file> -T -
Since this is a small part of a Huge backup program, if things behave this way, I am going to be in trouble.
Can somebody help me to figure out what is happening.
Thanks in advance
