I checked everything... but nothing changed.
I'd like to know if is a hardware or flexbackup problem.

I could try, but the drive is new, and I used two new data cartridge.

Sorry for my last email. it was not clear.


I can run with success the command within a script.
The user I run flexbackup is root.

I try this using a server with flexbackup working:

[flexbackup-help] writing to `/dev/nst0': Input/output error

[Michele C. <mi...@pr...>]

Hi,
I'm in trouble with a 920 internal SAS Hp.
I installed several flexbackup since 2003 with several hardware device 
(DAT scsi/usb, Ultrium2/3/4 , sony ait).
Now I have some problem with this Hp.

With each configuration I have the sam error:
  writing to `/dev/nst0': Input/output error

using tar o afio, compression o not compression.

The mystery is that using the same command used by flexbackup I haven't 
error.
For example if I try to execute this command from shell I have not problem:

cd "/tmp" && /tmp/collectexit.2376.sh find . -depth -xdev ! -type s 
-print0 | /tmp/collectexit.2376.sh tar --create --null --files-from=- 
--ignore-failed-read --same-permissions --no-recursion --totals --label 
"level 0 /tmp Tue Mar 15 12:21:18 2011 tar from server" --verbose 
--sparse -b 64 --file - | /tmp/collectexit.2376.sh dd ibs=32k obs=32k 
conv=noerror,sync of="/dev/nst0"

While using flexbackup I have this error :
dd: writing to `/dev/nst0': Input/output error
dd: closing output file `/dev/nst0': Input/output error

Could someone help me?
Thanks
Michele

Re: [flexbackup-help] What not to back up, and how to exclude it, on a Windows box?

[TeckniX <lo...@gm...>]

Your settings may be a bit different or just the way of seeing things, but I
feel that no matter what you'd have to reinstall windows and every program
installed. I would thus only backup desktop,my documents/user folder and any
other folder created to hold your data. Most programs can be customized to
save their data in a specific spot, make it a folder that gets backed up.

as making a level 0 backup take a very long time.

I am therefore wondering what should be excluded/pruned from the
backup, as things currently stand.

What are the best exclude/prune settings for this scenario?

[flexbackup-help] backup history broken with new full backup

[Rudolf H. <rud...@go...>]

Hi,

first of all: flexbackup is still great!

Ive configured flexbackup to do a weekly fullbackup on sunday
and a incrementell backup on weekdays ($device is a directory).
But every new fullbackup my backup history is broken.

I could not restore the state of yesterday after the current
fullbackup has run.

So I think I need one aditional backup of the full-backup I think.
What is the best way to do this?


Best regards
 R. Henze

[flexbackup-help] Backup of a system behind NAT

[Phil R. <phi...@ti...>]

I am currently reorganising my network and one of the machines I need  
to back up may end up behind NAT, relative to the one running the  
backup.

If I can get port forwarding to work properly and I have the relevant  
port entry in my ssh config, will flexbackup cope with this?

The alternative, I guess, would be to put the backup box on both sides.

It's capable of seeing it over samba but because it's removable, this  
is not very suitable. I was actually hoping it could be accessed in  
the manner of sshfs. It is important that the Windows box releases the  
directory soon after stopping using it, without user intervention.

[flexbackup-help] Backup to a remote directory?

[Phil R. <phi...@ti...>]

In an attempt to make my backups more efficient I am hoping to get  
flexbackup to run natively on my partner's Windows box, but I want it  
to send its data to a directory on my Linux box that is not suitable  
for exporting with samba.

I note that flexbackup can handle situations where the tape drive is  
remote, but can it do the same when the backup is to a directory?

[flexbackup-help] I/O Error

[Niall B. <ni...@la...>]

Hi André
Have you access to the flexbackup.conf from the old machine?
The archive may not even be in afio format. It may not be compressed with
gzip. It may not be compressed at all.
Depending on the admin's normal practice, they may have chosen cpio or tar
format as a preferred format.
Leave out as many of the buffer commands and flexbackup flags as you can for
now, and concentrate first on analysing your tape.
You could 'dd' a few blocks from the next archive into a 'file -' command to
get an opinion on format.
Try piping it into 'pax' for a listing, as it will also analyse and read
several formats.
Once you know what you have,
Adjust flexbackup.conf accordingly and it will allow you work with the
tapes.
I've used flexbackup for years on lots of platforms, and have been very
happy with it. The one 'gotcha' these days that stops me using it for home
directories is the seemingly unavoidable error with .gvfs directories for
gnome users.
Its local, remote and mirroring methods make for a great first tool to turn
to for regular backups and snapshots.
Hope you get your problem sorted,
Niall Brosnan

Hmmm... did you actually try -k , as afio requested you to do? It might 
be helpful in some situations. Given you're somewhere in the middle of 
the tape, this would perfectly explain the message IMHO.

Other way 'round, however, maybe adding a "-v" to make afio a little 
more verbose also doesn't hurt. ;)

I did not create the tape, as so, I cannot be 100% sure if the tape was correctly created.

I'm willing to pay someone to help me to fix this problem.

André;

not really sure about how to resolve this as we're not using flexbackup
that often anymore, but we still make use of an afio based backup solution:

Leaving out all this "magic", did you so far already try using "plain"
afio to list or extract things off your tape? I'd try

afio -t /dev/nst0

or

afio -i /dev/nst0

to see whether, after all, it is generally possible to get data off your
tape in your given environment. This way, you eventually might be
capable of making sure at least your tape is fine...

This is a flexbackup bug.  The attached patch addresses the issue with identifying later versions of bash.

Hello guys,

I'm trying to restore a tape that was saved using FlexBackup tool.
Unfortunately I'm having these errors that are driving me nuts! Anyone could help me to fix the problem?

Although as I stated in the previous email, this output seems to show that the tapes were working:

The tape seems to be correctly inserted and the ubuntu seems to detecting the drive:

How can I find out what BlockSize shall I use?

can you confirm from your dmesg that it is connected? even if 2 days ago you were able to connect, doesn't mean it's still connecting now. 

Look in the dmesg for the nst0 outlook

What can I do? How can I find out the correct Block Size?

Is the tape even connected? Looks like the /dev/nst0 isn't connected since afio is saying no input... 

Check to see what is on /dev/nst0

[flexbackup-help] flexbackup and cron

[tm t. <tm....@gm...>]

Hello guys
just wanted to post something I found out and that was undocumented in the
flexbackup manual, that might be helpful for people who are doing their
backup by flexbackup and cron.

I had flexbackup completing always when launched by command line and not
completing when launched indentically by the /etc/crontab file.
Same thing when written my own script, using flexbackup.
After many tests I found out that there was a difference between the PATH=
line in /etc/crontab and the PATH of the root user for an interactive login.

When launched in interactive mode, my flexbackup script would use different
commands/scripts than when launched by /etc/crontab.

I checked the PATH of the interactive root shell this way:
sudo bash
echo $PATH
and it was:
/usr/lib/kde4/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/X11R6/bin

Then
I updated the PATH= line at the beginning of the /etc/crontab file with
the same settings as before and everything worked perfectly.
The previous setting was probably missing /usr/lib/kde4/bin and
/usr/X11R6/bin and the other paths were in a different order (it was the
default of Linux 8.04 LTS)

Would be nice if the flexbackup team would point out which difference and
which specific file caused flexbackup not working when launched by the
default crontab.

And would be also very nice for cron users in a next release of flexbackup
to send the flexbackup.conf syntax OK message to STDOUT and not to STDERR,
as someone already filed in the bugtrack some years ago.

Tom
