With "bzip2 compression from BackupPC" and "tar tfj /dev/nst0"
# mt -f /dev/nst0 rewind
# tar tfj /dev/nst0
./backup/
./backup/aaa
./backup/bbb
./backup/ccc
tar: Skipping to next header
bzip2: Data integrity error when decompressing.
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: Read 1944 bytes from /dev/nst0
tar: Child died with signal 13
tar: Error exit delayed from previous errors
( only first archive is corrupt on the tape :| )

Without gzip/bzip2 , the tar process require very long time! Isn't it?
Tnx for reply
