Thank you all again

If you want to keep the backup in the same directory and that means same server, why u want to create pipes and all?

It can be easily accomplish by simple tar and gzip command.

it will be much easier doing this:

Code:
#!/bin/bash
 
  HERE=`uname -n`    # Stores the node name of the host server
 
 MYDIR=/home/users/Bashwork/Testing
  echo "starting backup at `date +%r`"
  # ==> `date +%r` returns time in 12-hour format, i.e. "08:08:34 PM".
  
  TARBALL="${MYDIR}/${HERE}-daily.tar.gz"
  
cd /
 
#This too?
 
  tar -czf - bin boot dev etc home info lib man root sbin share usr var  | gzip -9c - >${TARBALL}
 
 
  exit 0

will a named pipe always be size 0 on filesystem?

I did cat < myFile >> myPipe I was hoping that if I did ls -l, myPipe would now be holding the contents of myFile, and would be the same size. But it was 0. Also strange was that when I did the command above, cat did not return control back to the shell. Why? thanks (4 Replies)

virt-tar-out

virt-tar-out(1) 					      Virtualization Support						   virt-tar-out(1)

NAME

       virt-tar-out - Pack a virtual machine disk image directory into a tarball.

SYNOPSIS

	virt-tar-out -a disk.img /dir files.tar

	virt-tar-out -d domain /dir files.tar

	virt-tar-out -d domain /dir - | gzip --best > files.tar.gz

DESCRIPTION

       "virt-tar-out" packs a virtual machine disk image directory into a tarball.

       The first parameter is the absolute path of the virtual machine directory.  The second parameter is the tar file to write.  Use "-" to
       write to standard output.

EXAMPLES

       Download the home directories from a guest:

	virt-tar-out -d MyGuest /home - | gzip --best > homes.tar.gz

JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH

       This command is just a simple shell script wrapper around the guestfish(1) "tar-out" command.  For anything more complex than a trivial
       copy, you are probably better off using guestfish directly.

OPTIONS

       Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.

SEE ALSO

       guestfish(1), virt-cat(1), virt-copy-in(1), virt-copy-out(1), virt-edit(1), virt-tar-in(1), <http://libguestfs.org/>.
