Backing up my MacBook Air using Time Machine, can it backup while asleep?

I am backing up my laptop for the first time with Time Machine and a USB, will it still backup even when my laptop is asleep? I have noticed that when I close my laptop and then I open it again it connects to wifi again so I think that when its closed it isnt connected to the internet. But im not sure, can someone please help?

When plugged into power and asleep, your MacBook Air CAN and will backup to your TM.

You don't need to do anything.. both computers can use the TC and will create separate backups. It is simply designed to work with Time Machine.

Why when I connect my macbook air to time machine can't I use wifi any longer?

Whenever I want to send files from my computer to the time machine, I can't use any internet features...
If I look to which network my computer is logged on to, it says, Lara's Time Machine, which is not my wifi internet network.
Thanks in advance!

It sounds like you have two different Wi-Fi networks, one created by a Time Capsule and the other by your router, and the Time Capsule is not connected to the Internet. You should either use the TC as your router, or else connect it to the router with an Ethernet cable (if possible) and set it up to extend a wireless network in AirPort Utility. Details are in the built-in help of that application.

Why can't I back up my Macbook Air using Airport extreme.

I "used to" back up my Macbook air via Time machine using external harddisk connected to Airport extreme, of course back up wirelessly over WiFi. But now I've seen on Apple support page about Airport extreme that this cannot be done anymore. I've only 3 choices to do Time machine back up using Time capsule, external harddisk that connected to Time capsule or connect harddisk directly to Macbook air. But not harddisk connectd to Airport extreme anymore. So did Apple just change how backing up can be done recently? And is there any way I can back up using harddisk connected to Airport extreme?
Thanks in advance for any help.

Not sure what you mean here by "anymore".
Apple never did officially support Time Machine backups to a drive connected to the USB port on any of the Generation 1 though 5 AirPort Extreme versions. These were all the "flat" or "square" shaped versions of the AirPort Extreme.
Some users seemed to be able to do this though, while others.....like me....had nothing but problems when they tried it.
Time Machine backups are supported with a USB drive connected to the newer "tower" 802.11ac version of the AirPort Extreme.

Do you have the drive that is connected to the USB port on the AirPort Extreme mounted and displayed on the desktop of your Mac? If you do, it should appear as an option to choose as a destination for Time Machine backups, even though this is not officially supported if you have a Gen 1 through Gen 5 AirPort Extreme.

Need some help with backing up external hard drive using Time Machine

Hi all, I'm trying to work out the best way to back up multiple iPhoto libraries using Time Machine.
At the moment I have got an iMac and Macbook Pro, both of which have an iPhoto library (with different content). Currently these are not backed up at all. So what I want to do is back both up to an NAS drive, which I know is straightforward.
What I also want to do is create one iPhoto library on an external hard drive that I can use with my MBP, and then delete the iPhoto library on my MBP to free up some hard drive space (it's running slower and slower and I'm hoping that this might help it run quicker).
So, as I want to have the library on two seperate drives in case one fails, what I want to know is whether I could use Time Machine to back up my external hard drive as well as the internal drive of my MBP? Also, would I need to have the external drive connected at all times for Time Machine to "see" it?
I hope that makes sense, all I seem to be doing currently is going round and round and can't work out whether what I want to do is possible or not.
Thanks in advance

If I understand your goal correctly, you're considering using Time Machine as external storage, and it doesn't work that way. Time Machine keeps around what it can, and older stuff gets flushed as the storage available to Time Machine reaches its lower threshold due to the addition of newer stuff. When the older stuff gets flushed is not predictable.
It is possible to have several Time Machine backups aimed at the same target (this can be done with Apple Time Capsule, for instance), though you might want to partition the disks to ensure that the intended amount of storage is available. Different NAS drives have different features here.
NAS is only as fast as your network connection, and that's almost always much slower than the in-box I/O connections; a local disk will be far faster than a NAS disk, just because of the bottleneck that is wired gigabit Ethernet, and most WiFi is slower and sometimes far slower than wired gigabit Ethernet. FWIW.
If your MacBook Pro is old enough and you have $$ but aren't in a position to spend $$$$$ on a newer model, then consider an in-place drive upgrade.
If your network connection is fast enough to transfer the amount of data you're dealing with in a reasonable time, there are also hosted storage options.
You can use a NAS drive as storage independent of Time Machine, and relocate stuff there. (You'll still want to have backups of that data, as NAS drives — even NAS with RAID — can still lose files, become corrupted or otherwise ruin your data day.
As for your performance, keeping about 10% or so free on the disks is the local preference, but it's worth reviewing the performance of the whole system — Performance Monitor, Console.app, etc — to see if there's something else going on, or if your system load and personal performance expectations are exceeding what your MacBook Pro can provide.

How do I back up Wireless Hard Drive using Time Machine

I have a MacBook Pro and I'm running OSX Lion.
I'm having trouble setting up time machine to back up two USB external hard drives (named Portable iTunes and Portable iPhoto) connected to my Airport Extreme Base Station. I have a time capsule with a 3TB USB WD MyBook external hard drive that I'm using as the Time Machine Hard Drive.
Portable iTunes, Portable, iPhoto and MyBook are wirelessly mounted to my desktop.
Will someone please explain how I can set up MyBook to wirelessly back up the two portable drives using Time Machine?
Thanks in advance.
Wyatt.

Sorry, but Time Machine can only backup a hard drive that is connected directly to your Mac using USB or Firewire.

I have chosen to fil migrate from old ibook to new MacBook Pro using Time Machine after establishing admin account. I now have two admin. accounts and wish to delete the later one and transfer files manually. I am worried I will loose both accounts. ??

Use the Office for Mac and ignore using Parallels for that. If you have PC only apps you have to run that are MS Windows only then consider Parallels. Just transfer your main PC, using Migration Assistant. If you don't know how then simply read over Pondini's article called Lion or Mountain Lion Setup Assistant tips and look for the section on migrating from a PC. Millions have done what you are about to, it's far from leading edge these days, if you go to an Apple Store to purchase they will offer this as a service, something you might be interested in.

Can two HDs be backed up to the external using Time Machine

Here is my situation: I am using a MBP with the standard 160 GB HD. I am sure glad I went for the 160 GB instead of the "faster" 100 GB option because I'm down to just 15 GB now!
One huge file is my iPhoto 08 library, which has about 35 GB of photos in it - way over 20,000 photos and video clips from over 20 years now.
I want to use Time Machine to keep backups of it, but it really does take up a lot of MBP space.
I also have a portable USB HD I bought for my recent trip. It has like 240 GB of space on it - plenty to handle the iPhoto 08 library. I think there is an option in iPhoto for specifying that the library be on an external disk, right?
What I was wondering, if I put the iPhoto 08 library on the external portable USB HD, would it still get backed up with Time Machine, as though it were on my MBP internal drive?
Thanks,
doug

Time Machine will back up external drives if they are formatted in Mac OS Extended or Mac OS Extended (Journaled). Most drives ship formatted FAT32. The directions in this article are for formatting a Time Machine drive but they do a good job of getting rid of the FAT32 formatting so they will work for your purposes as well. People with PPC Macs should substitute Apple Partition Map for GUID when following the directions.
You also may have to drag the drive you want to back up out of Time Machine's "Do not back up" pane which is in System Preferences > Time Machine under Options.

You're skating on very thin ice. Mac OS X likes about fifteen to twenty percent of free disk space to function properly. An overly full disk can cause some extremely nasty problems.

One backup is not adequate for this type of data that usually has a lot of sentimental or business value. It would be best if you kept two copies of the data on different hard drives using different back up software. It would also be a very good idea to burn all your files to DVD/CD as well. One copy of the backups should be stored offsite.

Before downloading lion, i want to backup my computer with time machine and a G-DRIVE Slim. But how can i use time machine to only backup my system once?

Just wondering, how can i use time machine to only backup my system once? Just this once and not on a weekly basis?

Upgrade. My three year old Mac Pro and year old MacBook Pro have no problem. Both seem faster.
And there's your problem reading entirely subjective views on forums, from people that might or might not have decently maintained systems, good operating practices, or whatever....
Strangely, when most companies issue new software, it is because they believe (and believe they have checked) that it is better than the previous version.

To add to Niel's comment bear in mind that if you have a backup copy on an external HD and later delete the orignals on your Mac HD you will then only have one copy - so no backup.
If the pictures are precious you should have at least two copies, and ideally another copy kept off site,

HT204057 is there a way to use time machine with a backup drive connected to my AirPort?

is there a way to use time machine with a backup drive connected to my AirPort Extreme?

Unfortunately, this is not officially supported by Apple......if you still have the 4th Gen AirPort Extreme that you list in your equipment profile.
However, the new "tower" shaped version of the AirPort Extreme does now officially support Time Machine backups to a drive at the USB port of the device.

Restart the Time Capsule. Launch AirPort Utility and check for a firmware update.

HT201250 can I back up two different Macs using time machine to the same external hard drive?

I have a MacBook Pro and a Intel Power Mac Tower. The Power Mac is backed up to a 4 TB external hard drive using Time Machine. Can I also back up the MacBook Pro to the same 4TB hard drive using its time machine without altering any of the Power Macs backed up files on the 4TB hard drive?

Yes, as long as the backup drive is large enough.

Transfer photos and music to a new macbook pro using time machine

Help! I backed up my old macbook pro to an external drive using time machine. I want to transfer all of the photos and music to my new macbook pro, but it says I don't have permission. I can't get permission from the old mac because it won't turn on! I brought it to the genius bar and they couldn't turn it on either. They suggested I take it to Staples to get the files off.

Julie,
Probably because you used a different account name than you had on the old one. Create a new account with the same name you had when you created the backup and run Migration Assistant. Migration Assistant is in Applications / Utitlities and you create the user by clicking the Apple icon, then System Preferences, Users & Groups.
