I have a Seagate DP4 NAS connected to the network at the router by Ethernet.

I have just asked Crashplan to back up 2.6Tb of data, partially from my iMac SSD and partially from a RAID drive connected to the iMac via Thunderbolt.

At present, it is suggesting that this backup will take 4 days.

Does that seem normal or not?

Separate the tests for NAS performance and CrashPlan performance.

Test the speed copying say a 10GB file to the NAS manually. It could be the CrashPlan app that's a bit slow, it does a lot of things like versioning, compression, and maybe de-duplication.

Copy. Start stopwatch. Paste. Stop stopwatch.

Impossible to say when you're talking about a proprietary piece of software doing the backup

Is your iMac connected via wifi?

Test transfer rate, divide total data to be backed up by average transfer rate.

don't know about this particular model, but a seagate drive i had a little while back had a decent read speed, but absolute garbage write speed. so slow that it was actually the bottleneck for how fast my downloads went. I could get stuff off the internet much faster than I could write it to my hard drive. And this isnt on gigatown or anything. It was on pretty average VDSL.

You can see that whichever special snowflake invented Could backup had fibre...

If it takes this long internally, Lord alone knows how long it would take to the Cloud. May as well go on holiday..!

It's copying at around 55 Mbps although the speed rises and falls a bit.

Is that copy direct with your operating system, or crash plan?

I have a Synology NAS unit that will connect in three different ways - USB3, eSATA, or gigabit ethernet.

NAS write speeds from a SSD on a PC (large files):

USB3 120Mbps +

eSATA 100 Mbps +

gigabit Ethernet 100 Mbps +

Hope this helps

2.6TB is a lot of data.

This might sound like a silly question, but are the ports on the router 100 or 1000Mbps?

And the ethernet ports on your devices are...........????

Says 1Gb/second on the Admin screen for the NAS.

The router is a Vodafone issued one and says it is connected at 1000Mbps.

So many things could go wrong. For example I have everything at home connected to a switch and the switch to the router. The reason I do this is so that my internal traffic does not overload the router and Internet continues to run ok.

2.6TB is not a small task. If you have a NAS then make sure you use a native file system and enabled Write Cache if available.

If you have antivirus on your PC or NAS then those files are being scanned, one by one.

If you have other people using the network then your traffic will slow down.

And so on.

Since you don't seem to be interested in doing the diagnostics multiple people have recommended there's nothing I can do to help. Unfollowed.
