Backing Up Ardour Sessions to DVD
			_________________________________


Make sure the directory containing the sessions is small enough to fit on a DVD.
You can use the following command to check this:

du -csh directory_name

Note that this gives the size in `real' GB, not `marketing' GB. A DVD will hold
around 4.4 real GB. A salesman would call this 4.7GB, because his GB are
1000x1000x1000 bytes, but everyone else's are 1024x1024x1024 bytes. (This
applies to hard disks too).

If it's too big you'll have to copy the contents into two or more new
directories and burn them individually. To burn a directory to DVD (assuming
your DVD burner is master on the second IDE bus) use this command:

growisofs -Z /dev/hdc -r -J directory_name

To add another directory later to the DVD (assuming there's space):

growisofs -M /dev/hdc -r -J new_directory_name

To finalize the multi-session DVD (unnecessary with single session, but some
OS's like it to be done with multi-session DVDs):

growisofs -M /dev/hdc=/dev/zero   (this fills the remaining space with zeros).


Note that some DVD drives don't like multi-session DVDs, so it's better to use
single session DVDs whenever possible.



                       Importing Sessions from DVD
		       ___________________________


The DVD needs to be mounted before it can be read:

mount /media/cdrom0

Make a directory to contain the session(s) if it doesn't already exist, eg.:

mkdir /audio/projects/fredzeppelin

Copy the files from the DVD, eg.:

cp -a /media/cdrom0/whenthelevisbreak /audio/projects/fredzeppelin

This will copy session `whenthelevisbreak' to the /audio/projects/fredzeppelin
directory. The DVD is read-only, and so are the files you've just copied.
You need to switch on write permission before Ardour can use them:

chmod -R u+w /audio/projects/fredzeppelin

This will make all files in `fredzeppelin' writeable by the user that owns them
(you, hopefully). Now you can unmount the DVD:

umount /media/cdrom0

and eject it. You should now be able to open the session.

NOTE: If your DVD drive is a little sluggish you might get an error message
when you try to mount the disk. Try again. In extreme cases you might have to
eject it and reinsert it.
