What's the "obscure network setting change"? Maybe I should try that...

In the Terminal, type:

sudo sysctl net.inet.tcp.delayed_ack

If the value is anything but 0, type:

sudo sysctl -w net.inet.tcp.delayed_ack=0

It was 3, now it's 0, so perhaps I'll see an improvement. Does it require a restart to take effect?

Glenn, really helpful review and podcast.

I am looking to upgrade my 5 Mac home network from Tiger to Leopard and from a "g" router to 802.11n. While I currently have a serviceable backup system with a combo of Super Duper clones and Retrospect backup server (with two Firewire drives, one always offsite), I long to dump Retrospect and its inscrutable interface for the combination of Super Duper and Time Machine. I will continue to use my FW drives for the Super Duper clones, but would contemplate buying Time Capsule for the TM backup.

However, in reading your Time Capsule review, I guess I just don't understand the real value of Time Capsule over buying an AEBS n router with Gigabit Ethernet and plugging in a 1TB drive for a TM backup. I understand its probably a few bucks cheaper right now for a TC, but buying a separate router and plugging in drives seems to make it more forward compatible. What if prices go down on drives next year (and my storage needs go up) and you can get a 1.5TB drive for about the same price? Also, despite the "server grade" drive description, it seems that drives still fail before routers and that drive capacity becomes obsolete sooner than router speeds improve. Plus having one or more USB drives would make it easier to take one offsite, and it would be faster than to go through the extra step of archiving the TM backup.

Or is this solution not really "supported" by Apple? And is it any less set and forget than using TC?

It just kills me that this only has one USB port and no digital audio output. I want to replace my Airport Express with this, and hook up my laserjet and multifunction printer. I will never need all those ethernet ports, and I don't want to keep the Airport Express just so I can continue playing music over AirTunes! Seems like such little things to make it the perfect hub.
Also, does anyone know whether I could use half of this to store all my media, and then use the other half as my backup? I only need to backup one 200GB hard drive, and I'd like to use the other 300GB to store my iTunes library for playback.

[epskionline]

Whoops. Saw a couple of posts on the media storage aspect of TC later in the comments (after "read more"). Still not sure exactly how this implements, but it looks doable, which is key.

I posted before about an incompatibility of Time Machine with Intego Virus Barrier X5. I finally got a chance to speak with Intego Tech Support. The fix is simple:

Open Virus Barrier X5
Open Preferences
Click 'Scanner'
Go to 'Trusted Zone'
Click on '+' and add the drive you wish to use for Time Machine or drag the drive's icon to the Zone area.

As I no longer have Time Capsule and my new drive is not here yet, I cannot test this but it makes sense.

Update: My new WD Home Studio Edition 1TB drive arrived and the fix works. I timed my initial backup at 1GB/minute and auto saves work fine.

I've done an archive using Time Capsule. My question is: "Now what?" I end up with a sparse bundle representing the backup, but I don't see how gets used when needed. If I try to double-click on the sparse bundle, it opens a folder that includes a "bands" folder, which includes many subfolders. But none of this looks like the original hard drive and it's data. When I try to point Time Machine to a directly drive containing the archive, it doesn't see the archive. So how do you make use of the archive?

[moloko]

open the item you want to restore, run Time Machine.

e.g. launch Mail, run time machine. you will then be shown all the backups of Mail that Time Machine has performed.

[workingmacs]

I understand the process for restoring data from a standard Time Machine or Time Capsule backup, however that's not what I'm asking about. The archive process creates a sparse bundle. In the event that you need to use it, because you've lost your Time Capsule hard drive, for example, then how do you get Time Machine to recognize the archived sparse bundle. I thought it would show up when you point to it in Time Machine preferences, but that's not what I'm seeing.

[workingmacs]

I may have found a clue. It appears that there is a bug in the archive process. See http://www.macintouc...ws/timecapsule/

and look at the section on Archive-to-USB Glitch

[moloko]

you can right/ctrl-click on the time machine application and select 'browse other time machine disks'

Also you should be able to browse the backup disk image once mounted. Iinside it you should find a folder called something like 'Backups.backupdb', in which you should find another folder that will be named the same as your mac, then inside that there's a whole bunch of folders named by date+time plus a shortcut called 'Latest'. Open that to see the backed-up contents of your Mac.

I have a question regarding AFP performance: my TimeCapsule works with acceptable speed (say 30 secs per 100MB) when copying large monolithic files (e.g. audio/video files), but when I copy a bundle/package, performance is just unbearably slow (e.g. over two minutes for the approx. 10MB of the Calculator application). I tried the same tests also Mac to Mac and noticed similar sluggish behavior, i.e. the problem is not TimeCapsule specific, but seems to be protocol related. Hence my question: is this behavior normal?

Time machine backs up every hour eating up the space on an external drive rather quickly. Is there a method, other than simply turning Time Machine off, to do a daily or weekly backup rather than such a frequent hourly backup? I saw some Command Line instructions for changing the number of backups but I'm not comfortable working in Command Line.

Sure is! :-) Just download and use TimeMachineEditor
