Normally, I would recommend dump (aka "ufsdump" on SunOS/Solaris). It
works more closely with file systems, so it won't accidentally go
chasing down network mount points and stuff. It also has the
multi-level incremental facilities, which are nice. Its interface is
also more convenient when you must selectively restore specific files
from a large backup set.
The main reason I don't recommend it for Linux is that I remember
reading that it has a problem when the volume you're backing up is
larger than a tape. I don't know if this has been fixed since I last
looked (well over a year ago.)

You are right about this. They both operate on file systems. The boot
blocks and partitioning information exist below that level. AFAIK, the
only "backup" programs that preserve this data are programs intended for
mirroring drives, not for making backups

It allows for different kinds of incremental backup schemes.
If you make a level-0 backup, everything goes to tape. If you make a
backup at some other level (0-9), you get everything that was changed
since the last backup at that level or greater.
As for why not just full/incremental, you're thinking about backups from
the standpoint of a single user. Imagine instead a server that is used
in a corporate environment, with stuff changing all the time. In that
environment, a backup plan like this might make a lot of sense:
- a full backup every week
- daily incremental backups every evening
- hourly incremental backups all day during business hours
When you do your daily incremental backups, you want to backup
everything that changed since the previous day's daily backup. You
don't only want the files that have changed since the previous hour's
backup.
With a full/incremental scheme, you can't do this. So if the server
dies and needs to be restored, your worst-case situation involves
restoring over 168 backup sets (the most recent full backup, plus 168
hourly incremental backups.)
With a multi-level backup, your worst case situation involves restoring
30 backup sets. (the most recent full backup, 6 daily incremental
backups, and 23 hourly backups.)
Now, this scheme only requires three backup levels, not the 10 that dump
offers, but this isn't the only backup plan that might be used. With 10
levels, it becomes unlikely that someone's will create a backup plan
that requires more.

It's slightly off-topic for this newsgroup, but I'm not entirely conv-
inced that democracy is a Good Thing. The average voter has the
intelligence of a dormouse, and if enough dormice get together, they
can inflict untold savagery on their own citizens, as well as those of
other countries. Just look at the death penalty ... :-(

**NO!!!!** The original poster currently (or at time of posting) has
**ONE** corrupted file. The Linux NTFS read/write driver has the
potential to damage *MUCH* more than a single file, even if that's all
that's modified. For instance, suppose (hypothetically; I have no
reason to believe that this is the case) that the Linux NTFS driver
sometimes trashes a directory listing when modifying a file in that
directory. If that's the case, then replacing a damaged file has the
potential to effectively destroy all the data in that directory. (To be
precise, the data would still exist, but there'd be no way to associate
the data with appropriate filenames.) If the damaged file were in a
critical directory, like WINNT, then this could be quite disasterous.

Are you trying to run Netscape off a remote machine, or your local
machine? If it's a remote machine, you need to read the man page
for xauth or do "xhost +remote_machine_name". If it's the local
machine, then you should first try "xhost +localhost". I've found
that if you connect using DHCP, often the hostname of your machine gets
munged and this invalidates X's magic cookie file.

This is a very broad question. At the core, you must activate TCP/IP
networking on both Windows and Linux. Then you need to decide what you
want to DO with the network, and activate appropriate client and server
programs. Most people who ask this sort of question want to use file and
printer sharing, which means Samba on the Linux side. (It comes with
Linux, but may or may not be installed -- try "rpm -q samba" to see.)
This topic is so broad that you should consult some documentation on
it. One starting place is the Linux HOWTO documents
(http://www.linuxdoc.org/HOWTO/HOWTO-INDEX/howtos.html). The Net3-4
HOWTO, the Net HOWTO, and the Networking Overview HOWTO are good
starting points. You can also check the documentation on Samba at
http://www.samba.org (or, more precisely, any of the mirrors you can
reach from there). If you want printed documentation, there are several
good books on Linux networking. I've got several suggestions listed
(including one by me) at
http://www.rodsbooks.com/books/books-network.html.

I had no crash and therefore can not really help you. From what I have
read in this newsgroup:
1. disable AGP
2. remove possible conflicts with Mesa files previously installed
For both cases, the FAQ from nVidia is fairly complete and clear.
Good luck.

LinuxMall lists it on their web site:

I'm sure there are other sources, too, but I haven't gone looking for

Subject: MIME Types Not Working - Please Help
Date: Mon, 19 Jun 2000 15:30:01 GMT
I'm using Helix Gnome on RedHat 6.2 and I'm having trouble with MIME types.
I am able to use the MIME type changer capplet to change MIME program
associations and it works fine for many formats, including .mp3.
The problem is that when I change the default application for .AVI or .MPG
MIME types, Gnome ALWAYS trys to open up xanim when I double click a .MPG
from the Gnome File Manager. When I check the MIME type association, it
reflects the change I made (to use xtheater for example) but it still trys
to use xanim.
Does anyone know how to fix this?
Please e-mail me any suggestions you might have.
Thank you,
Kent A. Signorini

I have manage to configure the POP3 with Qpopper downloaded from
www.eudora.com and able to send mail out to any of the internet account
user, by using elm or pine or even the mail client in the xwindow.
But i just can't receive any mail sending to me from the internet account
user.
For example, my domain name is under1sun.com and I can send mail from
[EMAIL PROTECTED] to [EMAIL PROTECTED] , but I just can't receive any
mail from the reverse sequence.
This concept work well using a D-Link Internet Hub, if I configure the
D-Link Hub with Mail Server and I can receive all the mail to different
users.
Anyone, know about how to go about, please advise.
Thank you.

Hi Ravi,
Here's something i've learned:
#1 Slow connections are normally becuase of slow DNS servers.
#2 There's no way to fix that
#3 Free ISP's are normally slow.
#4 I too also used Freewwweb for about a week, then went to someone else.
Freewwweb in linux doesn't work to well (i mean, just dialing the service,
no advertisements =) )
#5 DSL,Cablr Modem, or ISDN, is much better.

Anybody opinions on how it compares to the Unix version? I
bought WP8 last summer, and it has problems opening some
MS-Word files, but it seems to work well enough otherwise,
though I don't use it very much now that I've found Ted can
open most RTF files.

If you have VMware, I'd load up Win9x/NT/2K inside it and run Internet
Explorer. (IE's the main reason I forked out the $100 for VMware...that,
and the occasional need for pcAnywhere and MS Money.)
If that's not an option, kfm does a reasonable job with simple pages.
There's always Lynx, too.
