FTP

Ade Falusi_1 — Wed, 21 Feb 2001 18:29:31 GMT

WE ARE TRANSFERRING 600 MB OF DATA FROM A UNIX SYSTEM TO AN NT SYSTEM EVERY MONTH.
THIS IS DONE WITHOUT DATA COMPRESSION AND TAKES APPROX 10HRS.

CAN THIS BE DONE IN LESS TIME OR IS THERE ANY APPLICATION OUT THERE THAT CAN MAKE MY LIFE LESS STRESSFULL.

Hi,
I havent tried copying 600MB from unix to NT..., but on a couples of machines I have NFS (up to 1.5 GB FS) to NTs and it works well, I use Reflection NFS gateway because its dead easy to maintain... I know there is a HP solution but cant remember the name now... CIFS?
that is based on samba like...

All the best
Victor

From what I've heard others say who have set this up I would go with Victor's last choice....
For that amount of data..just make a map connection between the two. CIFS (Common Internet File Systems) is was Samba is or uses, they are 'basically..' the same thing....

And Samba is free. www.samba.org

Sounds like you only have a 10 MB Ethernet connection. Have you thought about installing 100 MB Ethernet?
Compressing the data will take time to compress it and decompress it on both servers but may save some overall time if you have the disk space.
How far apart are these servers, feet, yards, or miles?
You might also investigate transferring the data nightly and combining it for the weekly run.

Ade,

The solution to the problem is to speed up the data link that you are using. Doing the math:
600,000,000Byte / (10 HR * 60 MIN/HR * 60 SEC/MIN)
Yields: 16,667Byte/second or 133,333bit/second. This must be a very slow connection! My ISDN here at my remote office is just slightly slower than this! FTP is optimized for this kind of connection better than anything out there; it was created back in the "old days" when the Internet was connected together by slow links.

So, go try to find out what is slowing down the data transfer between these two systems, and free up that bottleneck, or add bandwidth.

As an aside, upgrading from 10Mbit/sec to 100Mbit/sec LAN most likely is not going to speed up the slower components between the systems.

Hope this helps,
Brian Hackley

Never discount the manual method if your network is hosed. Are your machines not on the same LAN?

Lets see.. 600Mb would fit quite nicely on a CD-R! Takes about 45 mins to burn a CD depending on the speed of your CD burner.
Or do you have compatible tape drives on both machines?
