Backup Central

Greetings all;

I'm back from a week out in Nebraska, getting a son married off. I
hope that you didn't get too many bounces as my mailbox was full when
I got X running again, which had died due to my changing the default
prompt in bash, which in turn screwed up the X startup, it would get
to the mouse intialization, report success in the log, but hang at
that point with no further disk activity.

Anyway, on arrival here, it appears my 2nd tape drive in as many
months is in the process of dying.

I recently bought a DVD+-RW, drive and a 25 pack of +- media.

While its burnt several cdr's just fine, the media I have appear to
not be compatible with cdrecord unless I buy the cdrecord-DVDPro
version from Jeorg. I probably can, the $ is not a huge problem.

What I'd like from this group is some pointers on setting up the use
of this dvd drive as a 4.7GB tape equivalent. I'd be glad to be
somebodies "guinea pig" :-)

Be sure to verify what you burn. My experience in burning data DVDs
is limited to a set of 26 DVDs I made to move 120+GB of data between
locations (a high latency high bandwith data transfer). Of the 26
discs, 22 were read just fine, the other 4 had read errors on parts
of the discs. If I skipped over the file(s) involved I could read
the remainder of the disc, but each one of those bad discs had 10s of
MBs of unrecoverable data, Fortunately I was able to rsync from the
original server to complete the data transfer, but that wouldn't have
been possible if I had needed to do a recover from those DVDs.
I don't know if it was bad media or a buffer underrun while burning,
but the original burns completed without any indication of problems
(xcdroast with cdrecord). YMMV, but I would be sure to do extensive
testing before relying on it for backups. With video, minor data loss
just results in barely noticable dropped frames or nois, but with
data it can be catastophic. I would suggest running amverify on every
run, at least until you build some confidence in your burning.

My $.02,
Frank

Thanks Frank. I've now made 2 dvd's from unwritten dirs in the /dumps
assign, using a recent k3b (11-11), but I've not figured out how to
turn on the burnproof yet, and the burn screen isn't showing me
buffer status, like there isn't any, and the drive claims to have a
2Mb buffer.

Hi,
i'm using a dvd+-rw device for archiving my vdr-recordings.
you don't need to by cdrecord-DVDpro, there is a tool called
growisofs out there.
It handles dvd+ and dvd- correct, it is free, and AFAIK
it handles the various versions of buffer-underrunprotection
automagically.

That I've got, version 5.19-1. It doesn't display the buffer status
while k3b is burning with though, which is what made me a bit
nervous. However, so far, mounting the burnt disk seems to show each
of the files from a given /dumps/$DATE directory just fine. I need
to figure out howto turn on the verify for it though.
