I didn't want to use zip, I thought it was a reference to gzip. I've changed
it now to tar and it works fine. Thanks for the help!

(Do you really want to use "zip"???  It has to make tmp files.  Not really
fun when you are making large archives.. If you are using it just so that

Anyway, it could be something besides the size.  If you turn verbose off,
did find or zip compalin about anything else?  That could cause them to
exit with non-zero status.

Anyway, in your above sample the only thing that needs 2+Gb support is the

[flexbackup-help] backup error

[Bjorn G. <bj...@gr...>]

I just installed and ran flexbackup for the first time. While it looks like
it has what I need, it didn't finish the backup, ending with an error
message. Here are relevant entries from the log file:

You will need to do:

modprobe ide-scsi
modprobe osst

before the mt command. 

You can get around that by adding (IIRC):

alias char-major-206 osst
add below osst ide-scsi

to /etc/modules.conf.

Stupid, eh? You'll need to do:

mkdir /dev/nosst0 c 206 128

And:

mkdir /dev/nosst1 c 206 129

if you have a second tape drive (etc). But why anyone would buy a *second* 
Onstream tape drive is beyond me :-)

Ok, thats a problem.   It just seem like it won't let you
set the block size.  

You can try putting

 $mt{setblk} = "nop";

in the config file.  If you are using a blocksize that is what the drive
expects, it _might_ work out ok.

/dev/st0 = rewind-on-close.  When ever anything gets done writing to the
tape, it will rewind.  If you use this device flexbackup will overwrite its
archives and you get only one per tape.

/dev/nst0 = no rewind-on-close.  When ever anything is done writing to the
tape, it stays at its current position unless you move it around with mt.
This is what you want.

Re: [flexbackup-help] Problem with tape drive

Hi,

Thanks for getting back to me

I tried what you mentioned, and...

/dev/osst0 does exist, but if I try something like

mt -f /dev/osst0 setblk 0

I get

mt: /dev/osst0: no such device

Which seems strange (to me anyway))...

Just to report the detail, here's the ls -l for /dev/*st0

crw-rw---- 1 roor root 9, 128 Oct 26 2002 /dev/nst0
crw-r--r-- 1 roor root 206, 0 Oct 26 2002 /dev/osst0
crw-rw---- 1 roor root 9, 0 Oct 26 2002 /dev/st0

Once again, thanks in advance for any help

Cheers

Paul

Actually, for the Onstream, you may want /dev/nosst0. Onstream appear not
to understand open source, and forked the st driver, rather than add on
option to it to handle their non-standard protocol. Hence osst.o (for 
Onstream st.o).

Beware that prior to RedHat 9, RH RPMs didn't include /dev/nosst0, just
/dev/osst0.

[flexbackup-help] Afio smbmount

[Matteo R. <ma...@co...>]

I have 2 problems:

First:
Flexbackup with Afio does not backup samba mount points.
I have a share directory from the MSSQL server mounted with samba on my 
file server but it does not backup the files.
The permissions are o, also if I try to make a siple Tar archive it works.

Second:
In the conf file I  configured a set to backup" /home 
/var/spool/fax/donq /var/spool/fax/recvq /var/spool/fax/docq" but 
Flexbackup start and finish to backup only the home directory. When it 
stop it does not start the /var/spool/fax/donq but ends up with:

Depends on the archive backend used.

For some (like tar) just specify the directory in the filelist (with
"-extract -flist <mylist.txt>") and it will recurse.

For others you'll need to list all the files (do a "flexbackup -list" and edit
the output is probably easiest.)

Does

give an error? How about

  mt -f /dev/nst0 setblk 0

(variable block size)?

Sounds like it might be some sort of tape file-mark problem...

You can check the backup logs to see if block 767 is really where you want
to be to get the start of your second archive.  I bet its not.


You can also try manually positioning things to see if you can find where
the data got to:

  mt rewind ; mt fsf 1 ; flexbackup -list
  mt rewind ; mt fsf 2 ; flexbackup -list
  mt rewind ; mt fsf 3 ; flexbackup -list

No way to limit such sizes.

You can go down one directory level and/or prune things to chop it into
different-sized parts, perhaps.


(Yes, a good reason to split it up is for archiving to CD's... implementing
a good way to do that has been on the list for some time)

Re: [flexbackup-help] Broken pipe now. Worked before.

[Simon B. <ho...@si...>]

Hi Edwin,

To cut a long story short the problem turned out to be a mounted samba 
directory. The Windows servers has been re-organised so that the mounted 
location had moved. This resulted in an input/ouput error if any GNU 
command (in this case "find") tried to access it, even though the /mnt 
directory was excluded.

Re-pointing the samba share to its new location fixed the problem.

Thanks,
SimonB
