ATIH 2012 - First backup of 88Gb to local network drive taking 22 hours!

Tony,

Just to make sure, do not trust ATI time estimates, they are well known to be out of whack. If your backup actually tool 22 hours, it is a different story.

I have two "file servers." One is a a Western Digital MyBook World Edition NAS device and it is SLOW SLOW SLOW. I was seeing times as you described for large backups. My other device is just an old PC I installed Linux on and use as a file server. It is nice and speedy. I had the World Book device a few years before I built the Linux server and couldn't understand why I was having such a hard time with it until after I started using the Linux box alongside it.

I guess my thought is that it's possible you could have a slow network device as well. I spent over $400 on that WD device and am not happy at all with it because of this speed issue.

What speed is the network? 100Mbps, 1000Mbps? If you have a slower network or even just one slow connection on a fast network it won't be able to move data faster than the slowest device in the route.

Have the same problem with 2012 True Image Home - file backup from SSD to NAS 55gb took 14 hours - 1000mb link - what am I doing wrong?

Have reloaded software to try and speed up to no avail.

Brian,

Just to be sure the problem is not just in Acronis, you should do some testing with basic copy and paste commands using Windows to do the copying from your system to your NAS. See if the copy to NAS performace is better, the same, or worse using Window's vs Acronis's speed.
There are some settings in Acronis that could cause slow writes to the NAS such as compression, network speed settings, validation, consolidation, archive splitting, etc.

Thanks James - will do that - however the major time appears to be the "calculation" phase of the process as well as the actual file copy time. In fact I have done an incremental backup just 24 hours after the initial b/u (and it isn't a busy system) and it took about three hours to decide the estimated backup time was going to be 2 days - and then copied the files in about 20 minutes!

You could also try a "test run" by imaging the same volume to a directory on an internal hard drive and see if the same problems persist. This would at least indicate if the network and/or NAS were the problem for sure.

Well I changed the B/U proggie to Windows 7 Backup and saved 7 Gb - which took 2 hours on the same NAS set-up - so I suppose 55gb taking 14 hours is about the same speed. Perhaps I'll just split my backups into smaller chunks.

I would check for network issues. You should be getting much higher rates (1GB/min. or so). There may be bad wires or something causing lots of transmission errors. Is the router/switch showing 1Gbps connections for all devices?

Just incase anybody else has this "slow backup to network share" issue, I had the same problem. On a 1GB network, I was barely managing to achieve more than 2MB/s copy speeds! Copying a single large file from the PC to my NAS achieved 22MB/s, yet True Image would never move above 2MB/s.

Anyway, cut to the chase, the fix to my issue was to change several settings on the Network Interface device. I disabled "IPv4 CheckSum Offload" and "Large Send Offload (IPv4)", that seems to have done the trick. Acronis backups to network shares are now running at 22MB/s :-)

I hope this helps, I did a lot of searching across Acronis forums and there are lots of threads, but no resolutions!

Many thanks for this Gavin:

Two questions:

a) How do I disable those items?, and
b) What's the downside of disabling those items?

Many thanks :)

PS Changed all my cables to Cat6 and Router works up to 75mb/s

Hi Brian,

Disabling these options moves the process onto the CPU, rather than letting the Network Interface card do the checksum calculations. There could be a performance hit on your PC. If so, turn them back on again.

Click on Start.
Click on Control Panel.
Double click on the System icon (in Windows XP, you may need to click Switch to Classic View on the left hand side of the screen).
Select the Hardware tab.
Click on Device Manager.
Expand the section labeled Network Adapters.
Right click on your Ethernet network card and select Properties.
Click on the Advanced Tab
Click on IPv4 Checksum Offload (or Hardware Checksumming).
Change the value on the right to Disable.
Do the same with "Large Send Offload (IPv4)" if available. set it to Disable.
Click OK.

Then give it whirl and see what happens. If there is no improvement, it is easy enough to switch back.

cheers

Cheers Gavin

I have two Win XP PCs linked via a wired ethernet 100Mb/s router. I suddenly found that one of the PCs could not access file shares on the other, getting the message 'Not enough server space....'.

I had also found that ATI 9 was suddenly very slow to backup across the network.

I applied the solution found here:

http://www.techfleece.com/2011/03/03/how-to-fix-not-enough-server-stora…

to correct the network file access problem. I applied this to the sharing PC first and it worked perfectly.

I wondered if this was related to the Acronis slow network backup problem and applied the same correction to the other PC.

Bingo, problem solved.
