RE: Backup on Linux [DVD?]

["Jonathan Shore" <jshore@example.com>]

I'm actually a bit concerned with the lifetime of tapes.  Had a DAT drive
some years ago and found the tape lifetime to be abismal.  In that sense I
feel more comfortable with media such as CDs and DVDs (although capacity and
write speeds become an issue).

In this regard, has anyone had experience with DVD-RAM on linux?   There is
a new even higher density DVD-RAM drive/disk which should be available on
the market soon (I think giving something on the order of 7GB per side).

Im interested in this as well since most of my personal data is on hard
drives. The most feasable backup that I can think of is tape for now. They
usually can store 12GB uncompressed and upto 24GB compressed.

Not quite near the 70GB you re looking for, but better than the 650MB of a
CD-R.

By the way I have a question about tape backup. At work, we do all our
backup
on tape and I was using a trial version of Bru for a while. I didnt see much
of a difference between this and tar so now we do it the old way using tar.

We did have a problem recently when we added more data to the server. Tar
stopped at about 10GB, complained there isnt any free space and just quit.
That was after compression was turned on on the drive. Could this be a
limitation of tar or is it something else?
