For a few days i've trying to figure out how to make backup of my machine.
Since i have to duplicate it, i thought on tar'ing directories so i can
store untar them on the other mahcine, (wich is far away from this one)
and store it to have a safe copy.
But i still cannot tar var directory. In particular i have lots of
problems with /var/named/chroot/proc wich is filled with an incredible
ammount of stuff, like:
...
The question is, is there any of this files-directories that i can erase
to make a tar? by now im having problems with some files from the
-number- directories like:
lrwxrwxrwx 1 root root 0 sep 12 01:57 exe
wich is not linked to anything
what can i do?
It looks like the /proc file system, don't try to back up this!
Make a backup of one file system at a time, e.g. separate backups
of /boot and /.
Use the "-l" option to tar to make it stay in the same file system:
tar cvlSf /dev/nrtape /boot
tar cvlSf /dev/nrtape /
etc.
It will complain about the leading /, this can be ignored.
The "-S" option makes tar handle sparse files more efficiently,
the file /var/log/lastlog is an example of this:
# tar cf /tmp/test1.tar /var/log/lastlog
# tar cSf /tmp/test2.tar /var/log/lastlog
# ls -l /tmp/test*.tar
-rw-r--r-- 1 root root 603996160 Sep 12 08:17 /tmp/test1.tar
-rw-r--r-- 1 root root 10240 Sep 12 08:17 /tmp/test2.tar
