I want to copy files from one server to another server . Which would be the best solution.
The file is 12Gb compressed ufsdump format.We have 10MBps LAN.The source server is Sun Fire V880 Server with FCAL Hard disks adn the destination server is Sun Enterprise 450 Server with SCSI Hard disks.
1) FTP
2) rcp
3)ufsdump
4)tar
Please give a suggestion as soon as possible .
Thanks in Advacne.
Assuming this is a one-time push. Just use FTP.
If this is a activity you need more frequenty, I would still suggest using FTP but I would use a anonymous FTP setup with the incoming directory setup in write-only mode.
You didn't say which version of Solaris you are running. I haven't used it yet but the FTP daemon in Solaris 9 appears to be rather configurable. Related is ProFTPd which is a very configurable FTP daemon - you might investigate using this.
If security is going to be an issue, you should thinkg about using SSH. Although SSH gives you much better security - performance isn't going to be near what FTP will give you.
...do you have time to compress the file first?
You can use the compress utility or the gnzip/gnunzip GNU utilities.
The network transfer time could be reduced tremendously if you did.
It would also be faster if you had a 10/100 circuit running at 100mb...
Is this a one-time transfer - or does it occur more often?
It might be easier to come to the mountain rather than move it.
In other words, do you really have to move a 12GB dump file?
Can the file be analyzed where it is through a telnet session?

I would suggest using netcat if this is a recurring event. Check out the link here http://www.sans.org/rr/audit/netcat.php As the article states, its the swiss army knife of the networking world. I personally use it to back up files (running a simple bash script) between to ftp mirrors. It's over head is low and very easy to learn.
