Subject: | [Bug-tar] Tar Update command |
Date: | Mon, 15 Sep 2008 23:52:47 -0500 |
I
am using the update command to try to speed up our back ups.
I was thinking of using the update command to try and accomplish this. I
am having a small problem with my test. Am I doing something wrong, please see
below? First
Test tar
-v --update --file /root/test.tar 1 2 3 4 This
shows all 4 files were added to the archive. Great! Now let’s run it
again. This shows no files were added to the archive, Great! Now let’s
change file 3. Now let’s run it again and it shows it added 3 to the
archive, it worked great! Let’s
do the same thing but with the following command using the full path to each
file. tar
-v --update --file /root/test.tar /tmp/1 /tmp/2 /tmp/3 /tmp/4 This
shows all four files are added to the archive. Great. Now let’s run it
again!! This time it shows all four files were added to the archive, even
though none of them changed?? Why
would this add all 4 files to the archive every time just b/c I put the full
path? I
am basically trying to backup tar
-v --update --file /root/test.tar /home (where only the updated files get
added). Any
ideas, thanks in advance! Clinton Mills |
