Package: star Version: 1.5a57-1 It seems that a diff command has an error. This error occurs if at the same time there are new files in the target directory since the archive was created and some files, that were archived, were deleted. Take a look for a small and simple example (see my comment after signs '#'): # Create new directory mkdir test # Create file 'test.0' in new directory dd count=0 if=/dev/zero of=test/test.0 # Create a new tarfile with -dump option star -cvj -dump -acl artype=exustar -f=test.star.bz2 test # Create file 'test.1' in target directory dd count=0 if=/dev/zero of=test/test.1 # Look for differences between archive and target directory # See also my comments in the output of star program star --diff -vvj -dump -acl artype=exustar -f=test.star.bz2 test > diffopts=perm,type,nlink,uid,gid,uname,gname,size,data,rdev,hardlink,symlink ,sparse,mtime,ctime,dir,acl,xattr,fflags > Release star 1.5a57 (i686-pc-linux-gnu) > Archtype exustar > Dumpdate 1134393164.963331 (Mon Dec 12 14:12:44 2005) > Volno 1 > Blocksize 20 # So, that's right, file 'test.1' is only on disk > Only on disk 'test/': 'test.1' > test/: different mtime,ctime,dir > 0 drwxr-sr-x 2 root/staff Dec 12 14:09 2005 test/ > 0 drwxr-sr-x 2 root/staff Dec 12 14:13 2005 test/ > star: 'test' did not match > star: 1 blocks + 0 bytes (total of 10240 bytes = 10.00k). # Remove file 'test.0' from the target directory rm test/test.0 # Look for differences between archive and target directory # See also my comments in the output of star program star --diff -vvj -dump -acl artype=exustar -f=test.star.bz2 test > diffopts=perm,type,nlink,uid,gid,uname,gname,size,data,rdev,hardlink,symlink ,sparse,mtime,ctime,dir,acl,xattr,fflags > Release star 1.5a57 (i686-pc-linux-gnu) > Archtype exustar > Dumpdate 1134393164.963331 (Mon Dec 12 14:12:44 2005) > Volno 1 > Blocksize 20 # So, that's is also right, file 'test.o' is only in archive. # But where is the information that file 'test.1' is only on disk???!!! > Only in archive 'test/': 'test.0' > test/: different mtime,ctime,dir > 0 drwxr-sr-x 2 root/staff Dec 12 14:09 2005 test/ > 0 drwxr-sr-x 2 root/staff Dec 12 14:16 2005 test/ > star: No such file or directory.

CONCLUSION: This error is very CRITICAL, since DATA CAN BE LOST, if an incremental backup will be done on the base of output of command diff. I am using Debian GNU/Linux 3.1 (sarge), kernel 2.6.8 (was built from package kernel-source-2.6.8) and libc6 2.3.2. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
