bakunin, agent.kgb, hicksd8

on the same machine where i made backup and when i tried to restore on the same machine i got this error

Code:

root@cloapp1:/pcloneapp>/opt/freeware/bin/tar xvzf pclo_cloapp1_18_6_16_oraapp.tgz
/opt/freeware/bin/tar: This does not look like a tar archive
/opt/freeware/bin/tar: Skipping to next header
/opt/freeware/bin/tar: Archive contains obsolescent base-64 headers

My guess, is that since the this DISK is coming from IBM SAN Storage and the cache battery is dead, and I enabled "Enable Write Caching without Batteries" is the reason for above data corruption ?
I am not sure but investigating further.

agent.kgb, thanks for the z option with gnu tar

agent.kgb,
how would you combine gnu tar -z or -Z (compression) backup and restore with tee command ?

as was done by Rudic over here

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.
