You're putting a lot of effort into finding things to object to. ::-(

Do you agree that a CD burner in the UCC is useful for more than just
filez?

If so, do you agree that a fast and convenient one is, generally
speaking, better than a slow and inconvenient one?

You might very well disagree about whether it's worth money or effort
to improve the current setup, but that's a separate matter.

It's a bad idea to burn over the wire, so people need to put things on
temporary disc instead. They probably want to transfer more stuff while
the first one's burning and they need to have room to make an image from
the second lot as well. Hence 2GB as a minimum.

For CD backup purposes, it's nice to make a partition's worth of images
and then burn them over a period of days, deleting as you go. Hence
9GB. For tape backups it's nice to create archives on disk then stream
them to tape. Hence 9GB.

As for the fast ethernet - do you prefer transferring ISO images' worth
of stuff over fast ethernet or standard ethernet?

It's good to have that confirmed.

We already have enough tapes to do a backup or three - we don't need to
buy any. People don't seem bothered enough to do a backup that spans
tapes, whereas I know I would personally be willing to do a backup onto
one suitably large tape. I also like DLTs. ::-)

I expect so. However, I'm happy to make use of it, while it's here, if
we have everything we need to make it go. (Actually, we already do,
over the network, anyway. Guess I should give it a shot)

If we need to restore a DLT and no longer have access to it, there's a
number of drives on and off campus that are suitable.

I'm not sure why you think I would say such a thing, or what home
directory backups specifically have to do with it. It was a statement
about why UNIX machines are good for manipulating filesystems.

Sure it does, even though it doesn't stop me from using CD-R's. I don't
like throwing things away if I don't have to. <shrug> By that argument,
all CD-RW's are worthless.

(You might think that all CD-RW's are worthless, but it's been nice
to create a test disc, realise that it's broken, and try again
without throwing it away)
