backup solaris 10 machine before it dies
My Sunfire V240 server is going to die (has a faulty MB/SC). I am famillar with FreeBSD but not Solaris 10. I need to know how to tar/zip everything so i can ftp it over to another server.
I have root and ftp access via a limited account. I realize i could tar/zip everything and place it in the limited accounts ftp folder and transfer the files out. However, I don't think i have enough free space to do that (45GB used, 20GB free).
What are my options here?
Thank you.

In the same mode as omarfarid used to push a tar, you can use ufsdump to create a backup of the various partitions and store them on a remote server.
You can also do it in reverse
i.e. ssh root@server_to_be_backed_u
(I think the notation in the example is correct i.e. - for the file option (f) as standard output).
With this method you can then using ufsrestore to restore it.
Are you getting a replacement board?

I am not getting a replacement board, sun wants over $4,000 for a replacement, total rip off.. i am just going to let the server die, so i just want the actual files
You did not have it under support? Do you need the server? You could buy a system through the auction site at a quarter or half price compared to the cost you sited for the replacement board.
ASKER
it is not under support, right now the plan is to let this server die
did you try to copy / backup files to remote system?
ASKER
i'm confused, doesn't dd copy the partition? i'm looking to put all the files in a .tar file, or to tar/bzip all the main directories and scp them over.
i tried to tar bzip the entire /u0/home directory but it was too big. I need a way to tar/bzip on the fly to another server.
I have cygwin set up on a windows server 2003 box. also, i have freebsd set up on another server.
I'm guessing a network file share would do the trick, but i'm not sure how to get that going.. ideas?

The way omafarid outlined, you are using tar but instead of writing the archive on the Disk you are writing it through the standard output (-) to the ssh tunnel that uses dd to write out the data stream to a file.
On a system that could die, writing a backup to the local disk is somewhat strange. i.e. what have you achieved if at the conclusion of the tar process the system dies?
A network share would be through nfs /etc/dfstab with the exportfs.
dfstab on the host that hosts the NFS share is where you would set the parameters
then you would mount -t nfs host:/nfsshare.
I think that is right.
The tunneled data stream bypasses all this.
Note NFS might be using the UDP rather than a TCP connection mechanism.

SWEET JESUS!!! IT WORKS!!!! THANK YOU THANK YOU THANK YOU
'tar cf - / | ssh username@remoteserver dd of=/path/to/myserver.tar'
oracle 10.2.0.1.0 is running on this machine. I have no idea how to back it up.... will the tar suffice or do i need to take special steps?

How do you currently backup Oracle? rman?
you could scp the backup files. Using rman in a similar way.
You could setup Oracle on the other side and replicate the changes so that you have a hot bakup.
