Yes and as far as I can find out, that was when it still used the bttv
thing. I still see others having no problem. It could just be me.

Safe? It is all on two drives in one machine. That is not really safe.
Anyway. Backing up is a sort of redundancy and there will always be some
point where the redundancy will overlap and dual failure is possible.
The more you pay, the later that point will come. But if that point
comes, I will be sitting at Milliways drinking down several Pan Galactic
GargleBalasters.

As far as my advise is now. Go with a bttv card. Hauppauge does not have
those anymore. But first rsyncing for me. I am in the process now of
bringing all my data from softraid to reiser.
The way I do it is as follows:
I have formatted one partitions on wich I put all data that was on RAID.
I then delete the raid and make the two partitions that become available
normal mountable. I recheck the data I now have three times. I then
reformat one partition as reiser, copy the data from the raid to the
rieiser. Then recheck and reformat the other one. copy it again.
That way I have my data 3 times.
So:
Copy all data to C, reformat A and copy to A, reformat B and copy to B.
I have not yet figured out where to put my specific data.
One drive for all of the backup, another for incremetial backups of
stuff like /home and /etc
I am not really in a hurry.

more or less forgot about it because "It Just Worked".
Well, as long as the NT shares stayed up - which they did, sometimes.

Nope. Did not work. I did:
rsync --delete -avzr * /mnt/hdg4/hde3
(the -r option is already included as part of the -a option, since -a is a |
shorthand option for -rlptgoD)
Don't specify the source as a wildcard, specify it as a directory instead:
rsync --delete -avz . /mnt/hdg4/hde3
to achieve the same thing as your test.
This works, because there is now a directory root which can be recursed
(and the recurse option must be active for --delete to be effective),
instead of a filematch - which, er, can't easily be recursed.
It's not blindingly obvious this is necessary if you just think of rsync
as "cp on steroids", although the example given using --delete (search for
1st occurrence of "--delete" in the manpage to find it) does innocently
show a directory as the source, not files.
Ironically, you'd specified a directory as the source in an earlier post,
showing the sort of thing you'd like to do...
Oh BTW, have a look at --exclude or maybe --exclude-from if you're

I then deleted one file in the local directory and did rsync again. The

What am I doing wrong, because I would like to just write a script and
do:
#!/bin/bash
mount /mnt/backup
rsync -azr / /mnt/backup
umount /mnt/backup
But when files are not deleted from the drive, it does not work for me.
So what parameter am I missing?

It is more for larger datafiles, like movies, mp3's and pictures.

HArd drive backup?
|
|
|
Hello again.
I have been away due to HW problems. I had several partitions as
softraid and suddenly it did not recognised them. After some trying and
testing I deleted the softraid and am able to read the seperate
partitions again. The only thing I must now do is change /etc/fstab.
As the softraid did not do what I expected it to do I want to do my data
backup differently. What I want to do is a daily complete backup of my
one HD to the other. That way when one is broken, the other can take
over till I put in a new one.
What should I use to do this? dd, rsync, cp or even something else? I
want a 1:1 copy and would like to know experiences, advantages and
disadvatages of each way of backup.
