请教一个问题关于tar打包的问题

Question

我用
/bin/tar -cjvPf /data5/backup2/website/test.tar.bz2  /data5/website
打包 /data5/website下边有四个文件夹 但是总是有的文件夹打不上
而且解压缩的时候还会出现
bzip2: Compressed file ends unexpectedly;
        perhaps it is corrupted?  *Possible* reason follows.
bzip2: Inappropriate ioctl for device
        Input file = (stdin), output file = (stdout)

It is possible that the compressed file(s) have become corrupted.
You can use the -tvv option to test integrity of such files.

You can use the `bzip2recover' program to attempt to recover
data from undamaged sections of corrupted files.

tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
