If my Mac ends up with a virus, can I use Time Machine to go back before the virus?

I have recently just bought a 2TB external hard drive and have just backed up using Time Machine. I was just wondering, if my Mac was to become infected with a virus, would I be able to use Time Machine to restore my machine to back before it became infected with the virus? (So I didn't have to do a full factory setting resortation)
Thank you in advance for any assistance with this query.

My apologies. As a computer user since the days of Mainframes in 1970's, I tend to be rather precise in how I phrase things (a legacy of the old punch-card days). Also I write medico-legal reports for a living, again a field where precision is rather essential!
I saometimes forget that just because I read and write the word 'virus' as meaning just that, others (as you say) are prone to use it as a blanket term for malware and other 'irritations'.
Thanks for your clarifications WZZZ. Hope winter in the Big Apple is treating you well.

I have a powerbook G4 with macosx10.5.8 (as far as I know the latest possible OS with powerPC). Can I use Time Machine to restore my data on an Intel Macbook?

Well the newer TimeMachine model as stated in current Support pages isn't directly compatible on OS X 10.5 now, as noted in above link provided.
What OS X does your newer MacBook have running in it? (Not linux?)
With the current setup you have there may be a way -among other details in the support page- to do the migration of data from Mac, including a subnote on Time Machine, in a section below the main article with triangle by it, from links here:
•OS X: How to migrate data from another Mac using Mavericks 10.9:
http://support.apple.com/kb/HT5872
•OS X: How to migrate data from another Mac using Mountain Lion 10.8 and Earlier:
http://support.apple.com/kb/ht4889
In the support articles there are various troubleshooting and help items about the technology, some data back some time and whatever still stands would be there. Some archives are no longer current and say so.
Perhaps someoone still using older PPC Macs and Leopard 10.5, will say how to backup into a G4 PowerBook, from a Time Machine.
Unless the TimeMachine backup from the older PPC G4 PowerBook is used in the migration process of transferring personal account files from there to a new MacBook running (?) OS X. This probably could be done. You may be able to access older libraries, such as iPhoto, iTunes, etc and import them from the archive, to a newer Intel-based MacBook.
Sorry for any confusion.
I'll more carefully reply in the future.
Good luck & happy computing!

Using Time Machine to "go back" before Mac Mail problem

My wife's Mac mail account stopped receiving email 3 days ago. Attempts to fix it have been futile. (It can send but not receive. The activity monitor suggests that it is getting hung up on a particular email as it stalls at 13 out of 233.) Considering using Time Machine to go back to just before the problem. Questions: Is it possible to limit TM to (1) my wife's acct only or (2) Mail only?
My wife will definitely provide me a gruesome death if I lose her emails!
Cheers,
Nigel

Thanks, applefandan. I just haven't used Time Machine quite enough to a gained confidence, but after a little bit of experimenting and a bit of Youtube coaching (http://www.youtube.com/watch?v=fes93NW_KE0) I went back to pre-problem, and had no trouble getting back the mail my wife had lost over the past several days.
Now on to the next problem! . . .

Hi, I got my Mac in 2009 with photoshop elements on it - it's recently been wiped, however before the process we put Photoshop onto a hard drive, we then copied it back over and it no longer works, I'm getting error code 150:30 and I'm being asked for a password... any ideas how to get it working again?

You can never, never migrate an installed copy of PSE. It's just too complex and you can't get to all the bits and bobs.
First you will have to download and run this:
Use the CC Cleaner Tool to solve installation problems | CC, CS3-CS6
which will not seem to do anything, but is necessary to break the links within PSE so that you can pitch the bits manually. Then you will have to go around, not only to applications, but also to your username>library>preferences and most importantly to the library at the top level of your hard drive>application support>adobe, and remove everything you can find. Spotlight will not help with this kind of search, so don't try that.
Then you can install PSE from scratch.

HT201250 Can I use Time Machine on two different Macs to back up to one external drive?

Can I use Time Machine on two different Macs to back up to one external drive?
I have one 1T Western Digital backup drive that works well with Time Machine and my MacBook Pro. I now want to back up my wife's MacBook Air using Time Machine on her Mac and want to know if I can use the same WD external drive or if I need to get a 2nd back up drive? If I can use one external drive for the two Macs do I need to do something special on the drive or will Time Machine do it automatically?

Yes. You will need to configure Time Machine preferences on each computer to backup to the same drive. Note that you cannot connect the backup drive to both machines at the same time.

I am trying to get an answer to whether or not I can successfully use Time Machine with an external HDD connected to an airport extreme? Some forums say yes, some say no.

I am trying to get an answer to whether or not I can successfuly use Time Machine with an external HDD connected to an airport extreme. Some forums say yes, some say no. I'm also curious about formatting the hard drive to work both on my wife's MacBook Pro and my PC. Any help would definitely be appreciated.

You may be going on a recollection, that I share, that at one time Apple stated this would be possible:
In fact, Apple’s Time Machine Web page touted this very capability as recently as last Tuesday, as you can see from Google’s October 16 cache of the page
Effortless meets wireless. With a hard disk connected to your AirPort Extreme Base Station, all the Macs in your house can use Time Machine to back up wirelessly. Simply select your AirPort Disk as the backup disk for each computer and the whole family can enjoy the benefits of Time Machine.
But if you look at the current Time Machine page on Apple’s Web site, that text is nowhere to be found.
That was a long time ago, it has never been officially implemented, and at present they specifically say it cannot be done.
In summary, it may work, but probably won't, and even if it does it may not be reliable.

My guess would be it has created an entirely new backup of your drive when you upgraded to Mavericks.

Long story short....I restored my computer to an earlier point using time machine and now all of the previous back-ups are gone. My question has to do with itunes...is it possible to restore my itunes library to the most recent backup because the restore that I did was in march and the latest backup was in may....the reason being is that there were app that i had downloaded that are in my most recent back-up, that were not in the backup I restored to. Is it possible to just restore one application ie)itunes?

Is it possible to reinstall Mac OS X Lion on MacBook and then use Time Machine to restore to the previous backup I made before reinstalling Mac OS X Lion?

Is it possible to reinstall Mac OS X Lion on MacBook and then use Time Machine to restore to the previous backup I made before reinstalling Mac OS X Lion?

My MacBook was not normally booting up. It would turn on, make the Apple startup noise, and the bottom loading bar would progress just a little bit, then my MacBook would shut down. I tried rebooting it many times and the same thing would happen, it would just shut down. Then, I read that I can reset the PRAM (by holding Option+Command+P+R after the Apple startup noise comes). That worked, but now I get a screen that asks me to choose one of the 4 options (see: http://images.macworld.com/images/article/2012/07/lionrecoveryutilities-289404.j pg). I choose Restore From Time Machine Backup, but it progresses to 17.6% and gets stuck there forever. I tried doing it again, and it got stuck at 17.6% again. That is why I am asking if I should just reinstall Lion, then restore a previous backup on the fresh new Lion?

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.

Can I use Time Machine and an external HDD to move to a new mac?

I'm in the process of selling my MBP. I'm looking to buy a Mini with dual screens for a better photo editing experience. Here's the deal. I have to sell my laptop first, then I will use that money to buy the mini.
I have a portable 1TB HDD, I'm using Time Machine to back up my laptop. After my laptop is sold and I restore it.. Can I plug the portable HDD into my new mini and load the backup as if I didn't get a new computer?

HT201250 Can I use Time Machine to backup a LaCie Hard Drive connected to an Airport Extreme onto a My Book that is connected directly to a Mac Mini?

I have a LaCie 2TB hard drive connected to a Airport Extreme Base Station. I also have a 1TB MyBook connected to a Mac Mini. My question is can you backup selected files (photos) from the LaCie drive to the MyBook drive using Time Machine, or any other software? If it will cost a fortune, I guess I can always just copy the newer files over.

Thank you for such a lightning-fast response Niel :-) Can I just double check with you the following ...?
The external drive where my iPhoto library is located has three partitions - Time Machine Backup, Pictures (where the iPhoto library is located) and SuperDuper Bootable Clone.
When you say 'Remove the external drive from the list of items set to be excluded from the backup, and then add everything else on it' - am I correct in thinking that I should remove Pictures partition from the items to be excluded but leave the Time Machine Backup and SuperDuper Bootable Clone as excluded items?
On my 2TB external drive (the one I'm backing up to) there are 5 partitions - Time Machine Backup, SuperDuper Clone, Pictures, Photo Archive and Document Archive. The Time Machine Backup is 700GB of which I still have 473GB available - when I include the Pictures folder that contains the iPhoto library that will use up another 148GB but I think there's still plenty of room to use it.
When you say if the partition contain the iPhoto library isn't dedicated to it it may be easier to create one which is, the only item I have on the Pictures volume is the iPhoto library so I think that it's dedicated to it. I was going to add images from the Pictures folder on my MacBook Pro but haven't done so at this stage so I won't do so. It wouldn't matter though, would it, if I copied the images from the Pictures folder on my MBP to the 'Photo Archive' partition of the EHD?
Thank you once more for your reply.

I can't use Time Machine with a USB drive plugged into an Airport Extreme.

I connected an external drive to the USB port of an Airport Extreme, intending to use it with Time Machine and one of the laptops in the Wi-Fi network (call it Laptop). The drive is visible from the Disks tab of each computer’s Airport Utility but from nowhere else, in particular not to Laptop’s Time Machine preference.
Laptop is relatively new and arrived with Mavericks. Time Machine used to work on Laptop before I upgraded the rest of the network (a desktop Mac Pro and another laptop) from OS X 10.6 to Mavericks.
The drive is formatted as Mac OS Extended (Journaled). I have tried other external hard drives, with the same behavior. The desktop correctly use Time Machine to back up its internal drive to another internal drive. Another possibly relevant factor is that our DSL connection has recently been upgraded, and now uses a 2Wire modem that provides its own router, so Airport Utility’s Network Router Mode is set to “Off (Bridge Mode)”.
I would be grateful for suggestions of what to try next.

Can i use time machine with a airport extreme and a external hard drive

I have connected a hard drive to my airport extreme.
Now i would like to use time machine to back up my computers, and would like to do this on the hard drive which is connected to my airport extreme.
Next step is that i would like to be able to approach my external hard drive via the internet.
Is this possible or not?

Both are possible. However, Apple does NOT support Time Machine backups to AirPort Disks attached to the 802.11n AirPort Extreme Base Station (AEBSn). Doing so will potentially lead to data corruption and is highly not recommended. Please check out this excellent Pondini article for more details. This article also provides the Apple Support references that states Apple's position. Bottom line? If your backups are critical to you, then you may want to rethink your backup solution.
As far as accessing the AirPort Disk from the Internet, the following is the basic steps to do so:
Start the AirPort Utility > Select the AEBSn, and then, note the IP address shown.
Select Manual Setup.
Verify that Connection Sharing = Share a public IP address is selected on the Internet > Internet Connection tab.
Select Disks, and then, select File Sharing.
Verify that both the "Enable file sharing" and "Share disks over WAN" options are enabled.
Verify that Secure Shared Disks = With a disk password. (Recommended)
Verify that AirPort Disks Guest Access = Not allowed. (Recommended)
Select Advanced, and then, select the Port Mapping tab.
Click the plus sign to add a new port mapping.
For Service, select the "Personal File Sharing" option. (Note: This option would only allow Mac clients to access the AirPort Disks. If you want both Macs and PCs to connect, you would need to leave this field at its default value and enter the appropriate SMB ports to the mix of ports to be opened.)
In the Public UDP Port(s) and Public TCP Port(s) boxes, type in a 4-digit port number (e.g., 8888) that you choose. In the Private IP Address box, type the internal IP address of your AEBSn that you wrote down in step 1. In the Private UDP Port(s) and Private TCP Port(s) boxes, type 548. Click Continue.
In the Description box, type a descriptive name like "AirPort Disk File Sharing," and then, click Done.
Click on Update.
To connect to the shared AirPort Disk from a remote location using a Mac:
From the Finder > Go > Connect to Server.
Enter the Pubic (WAN-side) IP address of the AEBSn, followed by a colon and the Public port number that you choose in step 11 of the previous procedure. For example: afp://www.mydyndnsdomain.com:8888 or afp://123.456.789.123:8888
Click Connect.
You should be prompted for your user name and password. The user name can be anything you like; the password should be the Disk password for the AEBSn that you created in step 6 previously.
Click Connect.
