TI v.11 What would be a normal time to backup in following conditions ?

On average, most users report backup speeds to be about 2 GB per minute to an internal disk, about 1 GB per minute to an external USB disk, and somewhere around 1.5 GB per minute across a wired Gigabit LAN. But your mileage may vary.

I would say that you have something not performing as it should since your backup rate is about 0.05 GB/min, or a factor of 20 - 30 times slower than it should be.

Questions:

1. How are you backing up? Are you running the Windows version of TI 11 or are you using the TI recovery CD?
2. What happens if you copy a large file from your PC to the NAS? Time it with a stopwatch and see what the speeds are. If you have a 1 GB file then the copy operation should take roughly a minute. If it takes 20 minutes then you have a basic problem with the network or the NAS.

I've been trying to use the TI 11 (build 8,101) boot disk to backup my entire C: drive (140GB of data) to an external USB 2.0 hard drive. I let the full disk backup run all night night, but in the morning it said it still had 5 days to go. The progress indicator had barely moved. I repeated the process verifying different options (no compression, highest disk performance setting, etc.) but had the same problem.

I booted back to Windows to test the read/write speed of the external drive using a simple file copy. The Write speed to the device was approximately 1.2GB/minute, which works out to roughly 2 hours for my entire 140GB.

I've been struggling with this issue for a long time. Does anyone have any idea what I could do to resolve this?

Kevin:

Your disk transfer rate in Windows looks good. Slow speed in the Linux recovery environment usually indicates a lack of the proper USB 2.0 driver on the recovery CD. 

Has Acronis posted a more recent ISO image file for the TI 11 bootable media? If so, go to your account on the Acronis web site and check under My Products and Downloads for newer releases of the bootable media.

Otherwise, have you tried different USB ports on the PC? Try one that is directly connected to the motherboard. If you're using a hub, try bypassing it.

Mark,
I must apologize to you. It is not my usual behavior... to not react, when being helped.
Sometimes life decides on what happens in such way far beyond what we would like to happen.  

The slow backup issue is still pending. For sure when backing up to my NAS disk.
It takes several long hours to back up the system partition C:\ (Windows-XP Pro) (about 24.5 GB used disk space) This cannot be normal, but eventually it finishes the job anyway.

Actually I could try a similar backup to another disk (firewire connection) and myabe also to another PC on my inhouse (wired) LAN network.

Coming back to your questions :
1. I use the Windows version of TI 11

2. Since this was my opportunity to be back here and to read your advice,
I still must make the test to measure the time required to transfer a large file from system harddisk to the NAS. (using Windows Explorer or some other file manager) I will be back with the results.

This is only my guess: Normal copies will probably be fast enough, but True Image 11 will remain slow in comparison.

I have to make the "COPY large file test" with and without the security software active , and the compare the measured times.

Then I have to do the same test for a partition backup with TI11 (with and without security software).

I must mention that I'm not using Norton Security any more but Avira "Antivir Premium".
This seems to be very less demanding on the CPU power than Norton.

I also use WinPatrol and the COMODO firewall, which I both could stop running to improve TI11 running time. The RAM memory is 2GB, which (to me) does not seem to be a bottleneck to do the job at the speed that you mention.

Maybe the RAID cofiguration (writing double amount of bytes) of this NAS is slowing down the process, but I doubt if this is the major reason.  

I will be back "some" time later.

My (delayed) thanks

G.
