.IX Header "ПОПЕРЕДЖЕННЯ"
You must \fInot\fR use \f(CW\*(C`virt\-tar\*(C'\fR with the \fI\-u\fR option (upload) on live
virtual machines.  If you do this, you risk disk corruption in the \s-1VM.\s0
\&\f(CW\*(C`virt\-tar\*(C'\fR tries to stop you from doing this, but doesn't catch all cases.
.PP
You can use \fI\-x\fR (extract) on live virtual machines, but you might get
inconsistent results or errors if there is filesystem activity inside the
\&\s-1VM.\s0  If the live \s-1VM\s0 is synched and quiescent, then \f(CW\*(C`virt\-tar\*(C'\fR will usually
work, but the only way to guarantee consistent results is if the virtual
machine is shut down.
.SH "ОПИС"
.IX Header "ОПИС"
\&\f(CW\*(C`virt\-tar\*(C'\fR is a general purpose archive tool for downloading and uploading
parts of a guest filesystem.  There are many possibilities: making backups,
uploading data files, snooping on guest activity, fixing or customizing
guests, etc.
.PP
If you want to just view a single file, use \fIvirt\-cat\fR\|(1).  If you just
want to edit a single file, use \fIvirt\-edit\fR\|(1).  For more complex cases you
should look at the \fIguestfish\fR\|(1) tool.
.PP
There are two modes of operation: \fI\-x\fR (eXtract) downloads a directory and
its contents (recursively) from the virtual machine into a local tarball.
\&\fI\-u\fR uploads from a local tarball, unpacking it into a directory inside the
virtual machine.  You cannot use these two options together.
.PP
In addition, you may need to use the \fI\-z\fR (gZip) option to enable
compression.  When uploading, you have to specify \fI\-z\fR if the upload file
is compressed because virt-tar won't detect this on its own.
.PP
\&\f(CW\*(C`virt\-tar\*(C'\fR can only handle tar (optionally gzipped) format tarballs.  For
example it cannot do PKZip files or bzip2 compression.  If you want that
then you'll have to rebuild the tarballs yourself.  (This is a limitation of
the \fIlibguestfs\fR\|(3) \s-1API\s0).

.IX Item "--format raw"
Specify the format of disk images given on the command line.  If this is
omitted then the format is autodetected from the content of the disk image.
.Sp
If disk images are requested from libvirt, then this program asks libvirt
for this information.  In this case, the value of the format parameter is
ignored.
.Sp
If working with untrusted raw-format guest disk images, you should ensure
the format is always specified.
