What is the best way off using two external harddrives with timemachine?

Hi,
I have already searched the board but I am still not sure what the best way is to backup to two harddisk.
Here is what I want to achieve:
I have two identical external firewire drives. One is always stored at my parents house. I swap drives once a week +(not perfect, should be everyday but much better than nothing).+
Before TimeMachine I have used SuperDuper which made incremental backups on both disks.
Due to my "method" I never have both drives at home. So it will not work to clone the external disks.
Can I now simply swap the drives and TimeMachine will backup again on disk 2, what it has already backupped to disk 1? Like "catching up" the now missing backups for the last week?
Should I give the disks the same names or should I choose "change disk" everytime?
I appreciate any suggestions and experiences.
Best Regards
Olaf

Hi Olaf,
Germany . . . hmmm, nice talking to you!
OK - We seem to have a lot in common. I used SuperDuper all the time too. Loved it. NEVER had a problem at all with it. Ever!
I use Carbon Copy Cloner now - it seems a bit erratic - sometimes fails, sometimes works, can't find the pattern.
But enough of that.
YES - Time Machine will do exactly what you want (or does for me, at least.)
I named the two drives the same name and bounced back and forth between them, Time Machining to each. Works PERFECTLY every time . . . BUT - you MUST go to TM preferences each time and click "change disk". Simply reclick the one it sees. This seems stupid - but it's worked every time for me so far. So this morning, I simple renamed one of the backup drives (from Finder). Simple renamed it.
Went directly to TM with the renamed disk - clicked "change disk" - he instantly "saw" the newly named disk - and it Time Machined perfectly to the "newly named" one. I didn't even have to re time machine the entire drive - it picked up perfectly and backed up only 50 meg, which is all I changed!
So Time Machine seems to work perfectly backing up to two hard drives, with either the same name, or different names - TM doesn't care. But you MUST simple click "change disk" each time.
Let me know how it works for you. It really does work for me!

What is the best way to use two external displays at the same time?

One of my displays has HDMI, DVI, and VGA inputs. The other has VGA and DVI inputs.
MBP, early 2011

Kappy is dead on correct about Bridge Mode as a requirement for the Time Capsule.
Do you know how to check to see if the Time Capsule is configured this way?
Next question.....you really should not try to have two wireless networks....one Arris and another Time Capsule.....unless it is absolutely necessary. Two wireless routers in close proximity can create wireless interference effects that can cause problems with either...or both...networks.
Best to turn off the wireless on one router to keep the chances of wireless interference between routers minimized.
Are both the Arris and Time Capsule providing wireless signals?

What's the best way to connect two imac's with shared internet connection?

Hi
I plan on purchasing a new iMac (likely 2.4 GHz Intel Core Duo - 20 inch, probably will have leopard) and would like to set it up so I can share files and internet connection with my older iMac (1.25 GHz Power PC G4, 768 MB DDR SDRAM, using Tiger Version 10.4.11). I plan on using the Airport Extreme Base Station. I have a exterior cable modem for high speed internet through Shaw (internet provider) and my ethernet connection is through that.
I've heard a few things about this set up, but there are mixed reviews on everything. Would it be better to connect the Airport Base Station to my older iMac and then connect to the internet wirelessly through my new iMac or vice versa? I've heard some of the older iMac's have slow Airport Cards so thinking maybe should use my new iMac for wireless. One computer will be upstairs and the other downstairs.
There must be a few people out there who've done this, so any assistance would be great. Thanks for your help.

Would it be better to connect the Airport Base Station to my older iMac and then connect to the internet wirelessly through my new iMac...
Yes
This would allow the old iMac to use a 100 Mbps Ethernet connection while the new iMac can use a 802.11n wireless connection.
The old iMac only has 802.11g (54 Mbps) wireless capability.

Frankly, I expect a bit more courtesy and details from someone wanting help from fellow users.
Don't use your AT&T SIM/plan out of the country for the iPad.
Just purchase a SIM in France for about 15 euros and use that.

What's the best way to use your iPad instead of textbooks?

What's the best way to use your iPad instead of textbooks? I'm about to start a BSN program and have heard of using your iPad for textbooks instead of buying and carrying around 8 different books. Is there an app for that? Or do you buy or rent the books? What's the best solution?

Or, if you're like me and you want to do a lot of heavy reading, use the iPad because the low contrast on a Kindle is extremely fatiguing.
Seriously, though "screen glare will cause eye strain" is often taken as an article of faith, there's not a lot of good scientific evidence for it. "Eye strain" can be caused by concentrating on any close work for long periods of time. Looking up and focusing on something distant periodically is very helpful. Older CRT screens that flicker also can be aggravting. I'm not denying that some people find reading backlit screens uncomfortable. However, it's not dangerous. And, then, there are other people who find the higher contrast a backlit screen affords to be much less wearying over long periods of time.

What is the best way to use recovery files

I am working in FM 11 and have crashed FM a few times. What is the best way to use the recovery files and save them as the normal file? Then should I filter an explorer window for "recovery" so FM won't keep asking me if I want to use older recovery files? Thanks for your help.

> What is the best way to use the recovery files ...
Use a .recover file to extract only the new/changed content that would otherwise be lost if you were instead to open the .auto (if any), or .backup files.
> ... and save them as the normal file?
Don't. If the document crashed because of an internal data structure problem, the .recover file (although actually a MIF) is apt to contain that problem.
Before doing anything, preserve the debris. Copy the .backup and .auto files in particular, because as soon as you open the main .fm file, it's going to overwrite that .backup, and then the .auto at the next auto-save interval. You can dispose of any zero-length files or files with temporary names (which result from the crash itself crashing).
I typically:
preserve a snapshot of the debris
open the original file, and if it won't, the .backup
open the .recover, .auto or .backup (whichever seems the most useful candidate as a sourcing file)
copy in the changes from the .recover, .auto or .backup to the working copy
save the working copy as the original.fm, close the sourcing file
do a MIF wash on the new original.fm
clean up the debris in preparation for the next crash

What is the best way to zero a 'custom voltage with excitation' sensor from the front panel?

What is the best way to zero a 'custom voltage with excitation' sensor from the front panel?
Thanks for any help

Hi Donavan,
There are two options for zeroing with the NI-9237. You can perform offset nulling and shunt calibration with a strain task, or if you use custom excitation you can use software compensation.
See the Bridge Balancing, Offset Nulling section in the Load, Force, and Torque Measurements tutorial. Take a measurement before the strain is applied and subtract this from all subsequent measurements. See the above tutorial to consider the tradeoff in accuracy between these two options.
Hope this helps,

What is the best way to set up business accounts with multiple ipads?

Here are three different methods >

This article > iOS: How to transfer or sync content to your computer, http://support.apple.com/kb/HT1296
suggests using contacts groups.
When syncing contacts, you can choose to sync all of your contacts or only selected groups.
You can select a group of contacts to which all new contacts created on your iOS device will be added.
You can set up groups in the Address Book application.
If you are all going to use the same iTunes apps library, turn off "Automatically sync new apps" in the apps tab just below the list of apps. Then you won't get new apps on your device unless you select them.

What is the best way to hookup my airport extreme with my time capsule ?

what is the best way to hookup my airport extreme with my time capsule ?

It sounds like you have the AirPort Extreme configured as the "main" router on your network.
If that is the case, connect an Ethernet cable from one of the LAN <-> ports on the AirPort Extreme to the WAN "O" port on the Time Capsule
Power up the Time Capsule
Connect another spare Ethernet cable from your Mac to one of the LAN <-> ports on the Time Capsule
Open Macintosh HD > Applications > Utilities > AirPort Utility
Click on the Time Capsule, then click Manual Setup
Click the Wireless tab below the row of icons and make sure that the setting for Wireless Mode = Off
Click the Internet icon, the click the Internet tab
Insure that the setting for Connect Using = Ethernet
Insure that the setting for Connection Sharing = Off (Bridge Mode)
Click the Update button at the lower right of the window and wait a full minute for the Time Capsule to restart
Then power cycle the entire network by powering everything off....order of power down does not matter
Wait a minute
Power up the modem first, and let it run a few minutes by itself
Power up the AirPort Extreme next and let it run a full minute
Power up the Time Capsule next and let it run a full minute
Keep starting devices one at a time about a minute apart until the entire network is back up
You will need to reset the backup path from your Mac to the Time Capsule to get backups going again
Open System Preference (gear icon on the dock)
Open Time Machine
Click Select Disk
Click the Time Capsule to highlight it
Click Use for Backups or Use Disk and backups should begin again in a few minutes
If you do not want to leave the Mac connected to the Time Capsule by Ethernet, remove the Ethernet cable from the Mac to the Time Capsule, then log on to the AirPort Extreme wireless network
