Help with backup on SCO_SV 3.2 5.0.5 i386
Ulven
therefor my boss has put me on a case...
Installing backup on this server
In this server, there are installed a Seagate Travan tape station (10/20 GB)
The server are located in Sweeden, and i'm in Norway..
I want to set up my backup station to take backup of the server.
in my /etc/init.d folder i have a backup script,
-------------------------------script ---------------------------------

---------------------------------end of script.----------------------------
This script works for a while, then i stops, asking for tape2, but the tape
should take 10GB without comp.
There are only one 9GB harddrive in the server..
What block size should i use, can i use another script that formats the tape
before running backup etc..
This is important to me, i hope that some of you may help me..
Hope to hear from you...
Cheers!

Reached end of medium on output.
If you want to go on, type device/file name when ready.
Anyone?

You've run out of room.
Insert a new tape, floppy or whatever, type its device name and press enter.
You might want to try reading "man cpio", which explains this and tells
you how you can even have it spit out a different message.

I guess your real question was "Why have I run out of room?"
I would guess that your tape unit is not set for hardware compression.
The cpio headers add enough to run you out. Turn on compression

How can i run out of room on a 10GB (native) 20GB compressed tape, when i
have only 9GB harddrive installed, and it is not full....

Thank, i got some tips from this link...
But, what block size should i use on tapes?
I don't find anything on Seagate's pages :-(

Your problem isn't block size, but if you searcxh for "tape" at
http://aplawrence.com/mysearch.html you'll find more than enough to
satisfy just about anything you want to know.
Really, though, you should be using a supertar:

But, one more questions...
If a backup failes, the tape drive is been blocked until i reboot the
server..
example:
# tape status
tape: can't open '/dev/nrStp0': Device busy
There are no help in killing PID's etc..
Is there any other way of killing this session?

Do you mean while it's asking you to put in the next tape??? It closes
the device before asking that, though you will have to wait for it to
rewind bfore you can use it again.
If that's not what you mean, then you have a hardware problem or this is
one of those useless cheap Travan pieces of junk I see so much of
nowadays. I guess the newer ones are a lot better than what they used
to make, but I'm still no fan. If you have one of the old ones, this
type of behavior is perfectly typical. It's junk and you should treat
it accordingly.
If not, then you have scsi configuration issues: bad cabling,
termination, whatever: see http://aplawrence.com/Unixart/scsi.html
BTW, with 9 gb or less to back up, DVDRAM is a far better backup: see
http://aplawrence.com/Reviews/dvdram.html

I guess it just an old crap.. hehe.. its a Seagate Travan NS20 (10/20GB)
We have had a lot of problems with this type on WinNT 4 and 2000 to, bad
writings etc..
But the thing here is that if i try to run a backup with my script, it
shuddenly stops and hangs.. ctrl-d/z/x/q etc dows not work.. i have to log
off, and on again.. i kill the session, and i try to kill proc. that uses
the device.. but still hangs..
But with the script i got here at news seems to work, it runs with
compression now.. i have run backup for 4-5 times and it works great.
Is there a way that i can "see" or check whats on the tape... i want to see
that the backup is realy on the tape.
Server is located in sweeden, and i'm in norway you see... :-)
Cheers!

We, too, unfortunately have the Travan tape drives, and replacement
is an economic impossibility at this time.
One of the many funny problems we have had with this tape drive is that there
is a rubber belt driving a capstan. The rubber belt periodically slips
off, and the messages pertaining to this are, to be kind, ambiguous and
inconsistent. The only consistency is that the drive doesn't work without
the belt (Duh).
The rubber band comes off quite often. We have tape drive problems
on a regular basis, and before we call the hardware man we now as a
matter of routine check the rubber band, and replace it by hand if
need be.
I would not be surprised to find a full-grown squirrel cage, complete
with squirrel, inside a Travan tape drive. They will not sell us
another drive. Ever.
Good luck!

You really shouldn't be doing this. You should be using a supertar (

Well there were many Travans. Most I recall list the compressed
capacity using DOS type programs that compressed the data before
storage. Good current SCSI devices that most Unix people use have
native hardwae compression in the tape drive.
It might have helped if you had given model number. Otherwise
it's like saying 'I need a head gasket for my Chevrolet' with
giving year/model/etc.
