How can i use time machine using an ordinary external hard drive?

thanks in advance..

Yes. It must be partitioned using GUID and formatted Mac OS Extended, Journaled.
A whole lot about Time Machine for help with TM problems. Also you can select Mac Help from the Finder's Help menu and search for "time machine" to locate articles on how to use TM. See also Mac 101- Time Machine.

Does your external hard drive have it's own power supply? It should.
Is your external hard drive formatted with the NTFS file system? It won't work.
It needs to be formatted either with Mac OS Extended or FAT32.
(There are drivers available to add NTFS support to OS X but their quality is unknown, especially the "free" ones.)

I'm currently backing up using Time Machine and a Seagate external hard drive, how to do I restore on a new computer?

I hate to say it.. But I have never backed up!! I have thousands of pics of my son on this mac book, it got wet and NOW I'm backing up (as i type) to a Seagate external hard drive- I plugged it in, and then Time MAchine launched automatically. It looks like it's backing up my whole computer, is it backing up everything? photos, address book, documents etc? If my computer crashes tomorrow, how would I restore all of this information on a new computer?
Help, I'm computer iliterate- hence the reason I got a Mac (so easy to use). I need reasurance that it will back up! How do I continue to back up? Leave the external hard drive plugged in? I'm telling you I'm below the knowledge of "Backing Up a Mac for Dummies"

Time Machine makes a backup of the whole OS.X volume automatically, so you will have an exact copy of your hard disk in your Time Machine external disk. Also, Time Machine will make backups every hour, always that your Time Machine disk is connected. If you want more information, visit this site > http://pondini.org
To restore this in a new Mac, you have to use Migration Assistant. Just connect the Time Machine drive into the new computer, open Migration Assistant (it's in /Applications/Utilities) and follow the steps. You will be able to select what you want to transfer.
Also, if you have a brand-new Mac, you can do this during the initial setup. Setup Assistant will ask you to restore a backup, so connect the Time Machine disk and follow the steps

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?
Ed

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

Can I use Time Machine wirelessly to an external hard drive other than Time Capsule?

Since I already have a wireless router, I don't want to get Time Capsule. And since this is a laptop, I would prefer the external device *not* being physically connected to my MacBook Pro. Any suggestions on external hard drives and methods to accomplish this would be appreciated.
Chris

You can, in some cases.
If you have a desktop Mac, you can back up to a shared drive connected to it, over your network. See Time Machine - Frequently Asked Question #22 for setup instructions.
Some NAS drives work with Time Machine, to one degree or another, but I don't recommend that -- there are too many possible downsides. See the pink box in Time Machine - Frequently Asked Question #2.

Using time machine as backup AND external hard drive?

So I got the Time Machine so I could use it as a wireless external hard drive. Thought my computer just crashed and realized i realllly need a backup.... is there any way that I could back up my computer on it WITHOUT erasing my 100,000's of photos on the time capsule? Please be POSITIVE they wont erase.
Thanks

Sorry - forgot about this question.
My hard drive is about full. Its full of photoshop and rosetta stone stuff and I just would rather not loose it all if my computer were to crash (think 140GB).
As posted earlier, your best bet for that is a larger internal HD.
I just want one backup, maybe one that automatically backs itself up ever month/week and REPLACES the old one. Not looking for the time machine to work as it normally does, saving every backup it can. Looking to use the time CAPSULE as a backup, to save one copy at a time. Although not necessary, it would be nice to have it automatically REPLACE that ONE copy.
If you're going to have a backup of your system, you might as well use Time Machine. It's most recent backup is, in effect, a full backup of everything. If you let it do it's hourly backups, you'll never lose more than an hour of data.
You might want to review these:
What is Time Machine?
Time Machine Tutorial
and perhaps browse the Time Machine - Frequently Asked Questions *User Tip* at the top of the +Time Machine+ forum.
Yes, there are other backup apps; many won't back up to a network drive (such as a Time Capsule).
See Kappy's post on Basic Backup, complete with links to the web sites of each product.

How can I delete time machine backups from my external hard rive

My 2 TB hardrive is starting to fill up, so i went to check on what is taking all the space up, aparently time machine has use 321.90GB of space on my hardrive.
if it is possible I want to be able to delete a couple of backups but if i cant delete a couple of backups then i would not mind to delete all of the backups.
Thankyou

Time Machine manages space automatically. You should not delete snapshots yourself. You also should not use the backup drive for anything but backups. If there are non-backup files on the drive, move them to another drive (which must also be backed up.)

I can't get Time Machine to recognize my external hard drive.

I bought a new hard drive when we moved last September and it backed up my files once or twice. Now I cannot get Time Machine to recognize it at all.
I have tried to format it with Disc Utility and only get an error message: Error: Unable to unmount volume for repair. Is there anything I can do with this?

Is the drive showing up in finder?
Did you have it working then upgraded to Yosemite??
Amongst the many many bug in yosemite is a bug/s to do with no longer being able to use USB drive.
Did you try the fixes here.
OS X Yosemite: If a USB device isn’t working
Personally I would plug it into a computer running anything except Yosemite and you might find it works perfectly.. the issue then is not the drive.

How to I get Time Machine backups OFF my external hard drive?!?!?

I'm not asking how I restore a backup.
I plugged in my 250GB external to try out TM. Before TM did it's first backup I have 160GB free. After TM did its backup I have 1GB free. I no longer want to use TM and have told it to "Stop Backing Up" in Sys Prefs. The problem is that I still only have 1GB of space left. When I view the external in the finder I only see my 90GB of drag and drop backups, but it says the disk only has 1GB of free space. Are the Time Machine backups invisible? How do I reclaim my space back?
Thanks!

Looking at info, I found the folder was owned by root. Even with my admin privileges, I couldn't delete. I then found that root wasn't activated on that machine, so I had to do more dancing around.
In cases like this, you should be able to delete it from the command line by using sudo: sudo rm -rf directory (be careful with this command)
After deleting the TM backup folder, the drive still indicated that the former lost space was still lost. I eventually reformatted.
How did you delete it? Could it be that the folder was still in the Trash of the external disk?

How do I get Time Machine to backup an external Hard Drive to Time Capsule?

Just purchased 3TB Time Capsule. I have a 250GB ext hard drive where iTunes library and iMovie files are stored. The external HD is connected to my iMac The iMac's 250GB is at 50% capacity with iPhotos so i cannot move iTunes/iMovie library back to the iMac. I would like Time Machine to back up both the iMac HD and the contents of the 250GB external HD. Thank you.

To reformat the drive, move the data on it to another location, including a second partition of the drive or the Time Capsule manually, open the Disk Utility in the /Applications/Utilities/ folder to erase it, and move the files back.

Will Time Machine Back up an External Hard Drive Attached to my Mac Pro?

Apple TV is GREAT, but it quickly filled up my hard drive. My thought is to take my folder that contains all of my personal files and put it on an 1TB external hard drive. I'd then "point" iTunes to where this new folder is. First, is that the right approach? Will that mess anything else up? Second, can I have Time Machine then back this external hard drive up? So, I'd like to have Time Machine back up my Mac HD and the external HD. If Time Machine won't do this, is there a good back up program for Macs that is very turnkey?
Thanks in advance!!!

If the drive is formatted +Mac OS Extended,+ yes. While it's connected, go to TM Preferences > Options. If it's listed in the exclusion box, just select it and click the minus sign at the bottom.
If it's listed in gray, however, it's either formatted wrong or corrupted, and you can't remove the exclusion.

On imac 10.6.8 using current version of Aperture. How can I access the Aperture Library on my external hard drive that I use with time machine for backup? I can only access the application but not the library..

On imac 10.6.8 using current version of Aperture. How can I access the Aperture Library on my external hard drive that I use with time machine for backup? I can only access the application but not the library..

Go into Time Machine (the program not the bundle on the extrnal disk) and using Time Machine's browser go to the Folder where the library lives. You could look in the library bundle in Time Machine but that won't really tell you much,
If you want to make sure it truely has backed up your library you will need to restore it and open the restored library with Aperture.
If all this still has you confused you need to read up on Time Machine in order to get a feel for how it works, for what it is doing and for how to restore files from it.

How can I make Time Machine use the ethernet cable to Time Capsule instead of the wireless connection? Wireless is too slow; has been taking 40 hours to create an initial 142 GB backup.

Plug in ethernet .. in the computer.. turn off wireless.

Is there any way to create a time machine backup to an external hard drive with content already on it? I have a hard drive that i have used for pictures but when i try to run a backup it says i need to start from a blank drive. Can i get around it?

It would be much better if you had separate drives for the pictures and Time Machine backups.....but, if you want to use the same drive for both purposes, temporarily move the folder with the pictures to another location for safe storage.
Run the Time Machine backup on the hard drive and verify that everything is working correctly. Time Machine will format the disk for you in Mac OS Extended (Journaled) as part of the backup process.
Then move the folder with the pictures back to the hard drive with the Time Machine backups.
When you have tested to make sure that everything is working again, then and only then should you delete the folder with pictures from the temporary storage area.
Again....it would be much better to keep Time Machine backups on a drive just for that purpose, and other data on another drive for that purpose. This is clearly one of those times when the fact that you can do something does not mean to imply that you should do it.

HT201250 How can I migrate a Time Machine backup from an external hard drive to a new TimeCapsuls?

I just got a 2TB Time Capsule. I want to migrate my time machine backups on an external hard drive to the new Time Capsule. I have about 430Gb of files to back up; I don't want to wait 7-8 days for the backup, unless I have to. I am using OS 10.7.5 (forget which cat that is). I have mounted the TC drive as 10.0.1.1; I tried to drag and drop from old to "data" on TC, but I get the error "The volume is the wrong format for a backup." Any ideas how I can move my old files to the new, and bypass creating a brand new backup file?
Thanks.

Rather than do that, which means starting over from scratch, losing all your edits, organisation and so on, why not simply use iPhoto Library Manager to revert the Library to the older version? Easier, less destructive.
The instructions on that are here
If you really want to start over: you can access the Originals folder simply by going to your Pictures Folder and finding the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.

Re Time Machine
I have an external hard drive with files I backed up manually over the past 2 years 1TB of memory.
I am finally taking the leap to use Time machine to back everything.
will I have to reformat that drive, thus wiping my previous back ups?
can I split it the drive in two partitions?
Also
as I have two separate Macbook Pro's- one older than the other.
OSX 10.68
the other is
OSX 10.75
can I back them up separately?
or even synch and merge files and folders etc? between the two?

You CAN use a drive with files already on it to store Time Machine backups. But long term, that is not recommended. You do not need to reformat or re-partition the drive to do this. Once Time Machine Backups are established, you could remove the old files.
But do not delete Time Machines files with the Finder -- that can cause it to lose its place and lose everything.
With the cost of backup drives under US$100, it might be a better idea in the long run to get another drive. Best results from Time Machine is a drive about 3 times larger than the drive(s) you are backing up.
