Time Capsule slow file transfer

If I try to unmount the TC drive, the TM back-up immidiately stops, so I don't understand how that can be a solution. If I restart TM from the menu, the drive reappears when the TM back-up restarts.


BTW, another pb with the slow back-up: I have to have the computer turned on all that time. I have it in my bedroom so the noise disturbes be during the night.

Also, there is not room for all of the content of my 1 TB HD on my 1 TB TC so I might want to change around what I back-up later. And those changes will take time.

If I connect via Ethernet instead, I have an acceptable file transfer of almost ten times faster: 5 MB/s (wireless: 600 KB/s). So I guess I have to have a cable connected between TC and the computer until Apple has fixed the wireless capabilities to an acceptable speed.

If you have a newer hardware product, you have posted in the wrong forum.

You have posted in the Other Apple Hardware area.

You would want to post in the Time Capsule fourm.

Just for you to know, you may have sucess there more.

Good luck.

Has anyone tried +not using+ the Time Capsule app? I want to use the Capsule as an external drive connected via wireless, then use Retrospect as my backup application. Then I've got an updated wireless hub and a backup drive.

I've been having the same problem with the following set up:

--------------------
Network: 1TB Time Capsule 11n Airport providing an 802.11g/n network

+Home iTunes hub/file-server:+ G4 Mac mini connected via ethernet cable to Time Capsule at 100Mbit/s

+Do it all computer:+ MacBook Pro 17" connected wirelessly at 130Mbit/s

All software up to date, both machines running OS X 10.5.2
--------------------


After trying some of the suggestions posted on this thread without success, I have now found a fix that has completely worked for me. It involves a one-line entry into the terminal and is provided and endorsed by people who seem to know what they're doing (Mac admins and the like). You can read all about it at the link below. Note that I am not someone who knows what they are doing (in terms of Mac sys admin, and in fact many fields) and so can't take any responsibility if this !@£$s up your machine. All I can say is it works brilliantly for me with no observable side-effects.

+[Apple support admin: please feel free to advise on this wide-spread issue at any point, and ideally let us know when an official fix can be expected]+

I found it at the following link, but I think it originated on MacFixit:

Good luck!

even if I connect my macbook via ethernet to time capsule: iiiiincredibly slow.
Also if you want to restore something: it took 52 minutes to restore a simple file with 28MB..

Desperately asking Apple to take care of these problems!!

A quick read of the problems and discussions on the Time capsule forum gives three suggestions:

1) turn off your Virsu Checking software.

2) turn Off Spotlight Indexing of the Time Capsule.

3) do a Hardware Reset of the Time capsule. This seems to get it to go close to it anticipated speed.

I am having the same experience. I decided to set it up to back up four computers... three laptops and one MacPro... not a good idea, its very slow in most cases, creates a bottle neck. Not sure if I want to continue using it. I hope that Apple can do something about this

Your link absolutely worked, changing the default ACK setting from 3 to 0 worked amazing well. Just tested some big transfers, speed has increase massively.

wierd.

I don't know what have changed - some thing local on my mac or one of software upgrades from Apple? - but right now, one and a half month later, when I try, I get a speed of 9 MB/s using Ethernet. Almost double the speed compared to before.

It slows down for me too. I notice a slow down surfing the web then I have to restart it and it is fine. A little disappointing for an apple product, I hope there is a fix soon

I've been having issues with this as well. When I first got our TC, I really just set it up for TM and also moved some large, but relative infrequently used, files over to the general storage. The first backup went very well, and subsequent backups were so small that I didn't really notice. Just now, however, I noticed that it took over 5 minutes to backup a total of 10MB!

I am a sysadmin. I know for a fact that the ratio of data to storage capacity can affect data throughput. This is especially significant when dealing with media heavy applications, such as video editing over a SAN. Obviously, such a situation is far from the one dealt with in this thread, but it could be related. I'm at about 85% capacity on my 1TB TC right now. I'm going to move most of the data off onto my server storage and see if there are any improvements in transfer rates afterwards. I'd be interested in seeing if this works for anyone else.

The post about the 10.5.2 update could also be relevant. We'll see if 10.5.3 or subsequent updates resolve this issue.

Best luck with your tests.

quick question, all i ned to do is connect my time capsule to my computer to transfer files (i'm also using it as an external hard drive) but it is not showing up on my computer when i attach an ethernet cable between the two...?! is there something i need to do or does the time capsule not work in this way?

The Base Station involved needs to have an IP Address that is similar to the others on your other Macs, specifically, it must be on the same subnet. You either need to assign such an Address, or configure it to get one from another Router via DHCP.
