[Bug-tar] (no subject)

[Pierre Forget]

Hi,

I seem to have a specific bug in Tar. On a Linux (Slackware 10 with kernel 
2.4.32) server I use the following command to backup the main partition 
(root partition), with the Tar version 1.14:

tar -czpPlf /backup/backup-root.0.tgz --directory / --ignore-failed-read 
--exclude=backup --exclude=mnt --exclude=proc --exclude=sda3-dev 
--exclude=sdb1-dev --exclude=sdc1-dev .

This saves all the files, excpet the one's which could have been modified 
on the fly, which I can live with. If I do a restore or check the files in 
the Tar archive with tar -tf|less, I can see that I have all my important 
files.

On another server (Slackware 12 with kernel 2.6.23.1) I use the similar 
command (except for one partition exclusion) with Tar version 1.16.1:

tar -czpPlf /backup/backup-root.0.tgz --directory / --ignore-failed-read 
--exclude=backup --exclude=mnt --exclude=proc --exclude=sda3-dev 
--exclude=sdb1-dev .

The main major problem is that some important directories are not in the 
backup archive, such as the ETC, BOOT, LIB, BIN.

So, when I do a restore, the system cannot start. Unless I have a stupid 
typo, but I looked more than once before calling a bug.

I understand that I can switch to the latest version 1.20 (which I will do 
to make a check), but that may fool many people like me who are using the 
older version without checking with a restore. Unless some switches have 
changed, but I doubt those switches are obsolete.


Thank you,
