RE: [cobalt-developers] Backups - Newbie

Kevin,

I suggest using all of the same flags when you untar a file ( -xpzf ) as you
used when you tar'd it up ( -cpzf ).  Also since there are different
utilities that could be used to archive files it would be eaier to identify
the type of file if you used a .tar extension on your tar files.

I am a bit confused with this tar business... I do a tar on a particular
directory:

[root@ns1 /home]# tar -cpzf myfile.bak mydir

The first thing I tried was to copy the archive and restore it someplace
else:

[root@ns1 admin]# tar -xzvf myfile.bak

This succeeded, but when I tried to "rm mydir" without the -R it worked and
did not produce an error. I found this a little odd, but things get wierder.

I then went back to the original directory and removed just one file from
it. Then I restored from the backup (in the directory where the original
directory was located):

[root@ns1 /home]# tar -xzvf myfile.bak

The deleted file was not restored. I then copied the backup someplace else
and tried again to restore in a completely different directory:

[root@ns1 admin]# tar -xzvf myfile.bak

And still, my file was missing from the archive. What am I doing wrong
here??

Kevin
