Using pipes you don't need temporary diskspace and tar does not care whether it writes an archive onto disk or onto /dev/rmtX directly. This is all files to Unix. Try to use a combination of commands, pipes and files to backup compressed data onto a tape. Sth. like
Code:
# tar -cBf - /yourdirectory | compress | dd of=/dev/rmt0
B option (blocking) is recommended with pipes. Reverse the syntax to read data from tape again.
Code:
# dd if=/dev/rmt0 | uncompress | tar -xBf -
gzip is open source. What did you mean with "the license is only on one server"?
Doesn't 'compress' use the current folder to store the *.Z files ? If so I cannot do that (sorry I am mistaken. My Unix knowledge is limited). The folders where the backups are are over 90% full. I tried finding other places to move the files (and then compress them) but I did not have enough time to continue my search. Compression will have to be elsewhere (if there is room enough somewhere). The biggest backup folder has 10.5Gb and by extrapolating the compression time, it would take 2hrs to compress the whole thing on disk (I would not gain any time with this way. That is why I am looking for compressing directly to tape). This particular backup folder takes over 4 hours to be TARed to tape (without compression).
By "the license is only on one server", my teamlead said the licence for the few servers (1-2) we have GZIP on them is only valid those servers only ant that it cannot be copied on any other servers. Frankly I do not know if he is telling the truth or simply not knowing the answer at all. We have gzip v1.2.4 on those AIX 4.2 servers (they all have AIX 4.2). I sent an email to the gzip support for the whereabouts of the licence vs our intented usages.

Hello all,
Anyboby knows what is the reason by which the ouput of the command mt -f /dev/rmt0.1 status on AIX does not show the same information that in the rest of platforms UNIX (Solaris, HP-UX, ...)?
Then, what command of AIX is similar to mt- f /dev/rmt0.1 status of Solaris? We need it to... (0 Replies)
Hello guys,
on my Red Hat machine the /bin/mt status command gives the output dev/tape: inappropriate ioctl for device. This messages comes up after the Server has been rebooted.
Anybody an idea?
Thx

I want to compress backup files to tape using compress on our AIX 4.2
- Our TAR does not have compression.
- I do not want to use local storage to compress as most of the filesystems are pretty full.
- the only compressing tool we have is 'compress'
- tapes are 5Gb 8mm

I only about the principle of filesystems from the very basics on Linux and Windows. But I want to know if it is possible on an AIX 4.2 to create one NFS on a server which is pointing to a tape drive (/dev/rmt0) of another server ?
This is because we several backups to do on a 5 servers that... (5 Replies)
Dear all,
we are running SLES 11 where an iscsi tape library is
attached. To load the tape in a slot we are using for
instance the command #mtx -f /dev/sg1 load 2 which is doing
very well.
But after a server's reboot the device name of the loader is now
/dev/sg4 or /dev/sg5 I mean it is... (1 Reply)
I have an HP Proliant DL380 with Intel Processors that I recently loaded Solaris 10 with latest patches on it. I'm trying to do a ufsdump to an HP DAT 40 tape drive via SCSI, but I can't get it to do anything because /dev/rmt is empty. I've tried the following with luck:

Hi all,
I am facing problem with my Tape drive (hp) (/dev/rct0) on SCO Unix version 6.0.0. Sometimes tar works fine but some times it doesnot work and I have to restart the server to get it work. One reboot/shutdown is OK. to solve the problem. Error is "cannot open ... (9 Replies)
Dear all
First of all, my English not so good.
We have p52a (production server) and p52a (test server). Tape drives are VXA2.
When both servers were AIX 5.3, mksysb on production server and restoring to test server was OK.
The production server was AIX 5.3 and recently upgraded to... (3 Replies)
