TI 11 - Poor speed for network backup

I've recently upgraded to TI 11 and on the very first use I've noticed a severe degradation when I do a backup over my LAN. Here are some facts that clearly indicate the problem:

TI 11 backup to another drive: 25MB/s (the backup in itself is fast)
Copying some files over the gigabit network: 30MB/s (the network is fast)
TI 9 backup over the network: 8MB/s (TI 9 is decent)

but:

TI 11 backup over the gigabit network: 1MB/s!

I noticed that TI 11 has a configuration for network speed. I've use the default (max) and also set a value of 20MB/s but there was no effect. The throughput on the network was still around 1MB/s

There's no need to say that this renders it pretty useless for backing up large amounts of data. Is this a known issue of TI 11? Have others encountered the same problem?

I'm using XP SP2, True Image 11 build 8053, probably the latest.

 

E:TI 11 - Poor speed for network backup

Some more information: The target drive (on the network computer) is a RAID 5 of 4 drives with a stripe size of 64K. The controller is a 3Ware 9650.

I've did some more network copy tests:
* for 1 big file, the rate is 30MB/s
* for many small files the rate is below 1MB/s

From here I can infer that the TI network backup appears to the other computer like copying many small files which is slow because of the stripe size.

Now how can that be? The backup is just one file. Does TI do anything else than writing sequential blocks to the network file?

 

Re: E:TI 11 - Poor speed for network backup

Is this doing the backup from in Windows or from the TI CD?

Have you run a test doing a copy and backup to another network share? I doubt it's the RAID or the stripe size, however if you got the same "fast copy"/"slow TI image" results you could rule it out.

 

It's XP to XP.

Backup Computer with regular disk to computer with RAID = slow
Backup Computer with RAID to computer with regular disk = fast
Local Backup of Computer with RAID = fast

The only other thing that was slow in all my many tests of backups and simple file copying was copying many small files to the RAID computer (both locally and over the net).

 

Check your networking settings on the two computers (Control Panel > Network Connections > right-click on your network adapter and choose "Properties"). Be sure that you have both machines set up the same.

I had a similar set of symptoms on one of my machines. You could copy files to the machine quickly but going from the machine to the network was slow. The faulty machine had a different set of networking parameters from the rest of the PCs on the network. It had nothing to do with disk speed in my case.
