NAME

       cdrestore - Streaming restore from CD-R(W)/DVD-R(W)

SYNOPSIS

       cdrestore [-qvDFRTV] [-d device] [-i image] [-l size]
		 [-t track] [-c command]

DESCRIPTION

       cdrestore  is a utility to make streaming restores from CD-R(W)/DVD-R(W) disks. It's designed to work with any backup tool which is able to
       restore from stdin (like tar/cpio/afio).

OPTIONS

       -d device
	      The device name which is used for reading the backup.
	      (default: /dev/cdrom)

       -i image
	      Enables virtual image mode. The backup stream is read from the given image file. You have to use this option, if you  are  restoring
	      from a dumped image too.
	      (default: none)

       -l size
	      Specifies the media size. This value is used to display the free space on the media only.
	      By  default the given value is taken as megabytes. You can append a single letter to the number to select: (k)ilobytes, (m)egabytes,
	      (g)igabytes or (s)ectors (e.g. 170k, 4488m, 350000s).
	      (default: 650m)

       -t track
	      The number of the data track on the media for reading the backup.
	      (default: none)

       -T     Enables test mode. The complete restore process is done to test data integrity (includes CRC checksum test, if  available),  but	no
	      data is output.
	      NOTE:  This  only  verifies  that the data is readable by cdrestore at all. This doesn't guarantee that your backup software will be
	      able to do a real restore with the data.

       -F     Forces cdrestore to begin the restore in the middle of a multi-disk set. This may be useful if you have lost a disk  or  a  disk	is
	      badly damaged.
	      NOTE: This will most probably start the restore in the middle of a file. It's up to your backup software to sync to the beginning of
	      the next file.

       -R     Disable the kernel readahead for the CDROM device during the restore process.  (see cdbackup(1) Known problems)

       -c command
	      The command which is executed whenever cdrestore needs to request a new media for  multi-disk  backups.  This  command  (or  script)
	      should  prompt  the  user  and  return  after the device is ready again. The command receives one argument, which is the device name
	      passed with -d. This can be used to issue commands to the device like ejecting the media.
	      (default: use internal diskchange prompt)

       -q     Queries the media, prints out the contents and exits.

       -v     Enables verbose mode.

       -D     Enables DEBUG output (probably not useful for normal use).

       -V     Prints out version information and exits.

EXAMPLES

       Query the 700 MB media on /dev/sr0:

	      cdrestore -d /dev/sr0 -l 700 -q

       Restore a tar archive to the current directory from track 2 of a 702 MB media on /dev/scd0:

	      cdrestore -d /dev/scd0 -l 702 -t 2 | tar xf -

       Query the contents of a virtual image:

	      cdrestore -i /tmp/vimage -l 4488m -q

       Check data integrity of track 3 in a virtual image after dumping it to DVD media:

	      cdrestore -i /dev/dvd -t 3 -T
