Hi everyone, I make several backup with bzip2, it seems that he has the better compression. I do my backup like this for several folders. tar cvf - /home/data/ | bzip2 -9 > /backup/data.tar.bz2 When i test the archive with bzip2 -t archive.tar.bz2, everything is correct when the archive is under 1 Go. But i get CRC error when it's upper .... Has anyone experience this ? -- Franck
