I have a new external drive for my time machine. My hard drive of 650 gb is full. It is reallyslow backing up to my external drive. I have to stay near by as it stops after an hour or so. If I'm not here to restart it, I lose all that time it could have been backing up. It says it is going to take 581 days. Eventually it will say 12 days. Back up time is all over the place. How can I keep the machine backing up when I sleep at night.

I would go into your  in the upper left corner of the mac
Click on system preferences
Click on energy saver
Change the computer sleep and display sleep to never.

Trying to use a new, larger external hard drive for my Time Machine backup. However, every time I start the backup, it gets started then fails. And, I can't delete the few files that did save on the external. Sort of a catch 22. Any ideas?

Is it a USB hard drive? USB hard drives have the problem of not giving full speed if they are hooked up on the same bus as keyboards and mice. Double check your profiler to make sure that is not a problem. If it is Firewire, make sure there aren't other firewire devices in use at the same time. I recommend not only keeping a Time Machine backup, but also a clone, and if you do use Time Machine, to make sure the Time Machine drive or partition is at least twice the size of the original drive.

I have a 250GB western digital external hard drive for my time machine backups. if i just want to backup and recover my photos and movies how do i do that with time machine?

I have a 250GB western digital external hard drive for my time machine backups. I did not download the software that came with the external HD. If I only want to backup my photos and movies from my Macbook how do I do that in Tme Machine with my external HD?

Format the HDD in Disk Utility>Erase to Mac OS Extended (Journaled) and the open System Preferences>Time Machine and set up the external disk as the Time Machine HDD. Then look at the Options, and exclude what you do not want backed up.
Ciao.

Do you get this window when you hold down the Command+Option keys and launch iPhoto?
If not then you're not holding down both keys long enough.

How can I use one external hard drive for both Time Machine and iPhoto Library?

I have been using a 1 TG LaCie external hard drive for Time Machine backups. My (older) Mac has 160 GB and is almost full. I would like to move my iPhoto Library to the external hard drive, but I've heard Time Machine doesn't share one space well. Should I
1. create another partition (but will this erase what I've already saved) with Disk Utility? *I am running Snow Leopard*
2. create another volume to use for iPhoto, and if so, should the two volumes be of equal size?
3. leave it with one partition and move the iPhoto Library to the same partition with Time Machine back ups?
I know I don't need the entire 1 TG for back up of 160 GBs. Please advise the best path to take. Thank you!

You are getting incorrect information from your ASP. If you look at drive specifications the heat generated is no different for high vs low capacity drives.
I have upgraded the internal drive in my iMac 2007 with a 3TB Hitachi drive without any heat issues or other problems.
Larger hard drives have higher density platters so to access any given amount data the drives travel a shorter distance. Higher capacity drives should therefore run cooler than lower density drives because the drive spends less time spinning to access data.

I am trying to setup a new external hard drive as my Time Machine

I purchased a new 4TB external hard drive to store my stuff on. I have formatted the hard drive to work on my iMac but i cannot get it to successfully sork with Time Machine. I have tried anything and everthing that I could find on the matter and cannot seem to get it to work. I am constanly getting errors. Any ideas? Your help is appreciated!

Thanks for your suggestions. Whatever was happening seemed to be solved yesterday morning, my Time Machine is now up and running with the new drive.

Can't use my external hard drive for the time machine

I have a mac mini and i'm having a time trying to back data using the time machine to my external hard drive

you need to format the external drive. To do that (if haven't got anything important on that external hard drive at the moment) select finder > Go menue > then utilities > open disk utility > then select you external hard drive and partition it to the size you want and format it the Mac os extened journaled.
Once you have done the above, re open time machine from system preferences and brows the disk. Time Machine will then re format it to its own format and start backing up.....

What is the best external hard drive for iMac time machine?

I need to purchase 1TB external hard drive to use as a backup drive for iMac (lion) Time Machine. I currently have the Lacie little disk but I need more storage. All I need is a simple USB connection.

I've been happy with my silver FW Western Digital drives, I use two daisy chainned together (1TB, 2TB). These were the ones sold for mac's so they have a aluminum look to them. Only a bit more expensive than their black USB brothers.

Formatting an external hard drive for Mac/Time Machine.

Hello-
Just purchased a Time Capsule to use both as a wireless Network and backup hard drive. Both are working great. However, I have an external hd (500 gig "My Book") I used with a previous computer (PC). I would like Time Capsule/Time Machine to backup everything on the My Book external hd but I realize I need to reformat in order to have the Time Machine backup this drive. It appears that the only way to reformat the external hd is to erase it's contents. This isn't an option for me as this drive is almost full and has a ton of data I do not want to lose. Can anyone elaborate on how I can reformat this disk so it will be compatible with my new setup without losing any of it's contents? Thank you for your time and help.
Matt

Some 3rd-party apps, such as iPartition, claim to be able to do that. But they +*very prominently+* warn you to back up first, in case something goes wrong. And there have been a few posts here where something did go wrong and the user hadn't backed-up, so lost everything.
iPartition (and I think all the others) cost money, of course. Instead of spending it there, your best bet is to get another external HD, a larger one. Copy the data to it, reformat the WD, and copy it back. Make sure Time Machine is backing-it up to your Time Capsule (ie., not listed in the exclusions box of +Time Machine Preferences > Options).+
Then erase and partition the new one. One partition should be at least as large as your Mac's internal HD, the other 500 GB or more. Use this drive for "secondary" backups of both, via CarbonCopyCloner or SuperDuper. [CarbonCopyCloner|http://www.bombich.com> is donationware; [SuperDuper|http://www.shirt-pocket.com/SuperDuper/SuperDuperDescription.html] has a free version, but you need the paid one (about $30) to do updates instead of full replacements, or scheduling.
You might even want to get a portable HD for this, so you can take it off-site and also be protected against fire, flood, theft, direct lightning strike on your power lines, etc.

How can I reformat my external hard drive from the time machine format to regular format?

Ok so when first starting out I got an external hard drive for my time machine, little did I know I would run out of space really fast and would need to buy a bigger and better hard drive. Now that I did that, I have my old hard drive that I would like to use for copying material form my laptop to my desktop. However, it is still set as my time machine and tries to back up my lap top every time I plug it in. Also, it says that about half of it is still filled with stuff. I erased everything on it. I just want to reformat it so that it is like I just bought it.

I had the same idea as you however when I tried going to Disk Utility and I tried to erase it an error message came up telling me that it is unable to erase.
Unable to erase, or unable to unmount?
If Time Machine is trying to back up to it, or some other process is using it, Disk Utility won't be able to unmount it. Turn Time Machine OFF; if you have the drive open via the Finder or any other app, close it or quit the app(s).
At worst, start up from your Install disc or other alternate source and erase it from there. If you're not sure how to do that, see the yellow box in #1 of Formatting, Partitioning, Verifying, and Repairing Disks.

When Time Machine backs up a portable Mac, some of the free space will be used to make local snapshots, which are backup copies of recently deleted files. The space occupied by local snapshots is reported as available by the Finder, and should be considered as such. In the Storage display of System Information, local snapshots are shown as Backups. The snapshots are automatically deleted when they expire or when free space falls below a certain level. You ordinarily don't need to, and should not, delete local snapshots yourself. If you followed bad advice to disable local snapshots by running a shell command, you may have ended up with a lot of data in the Other category. Ask for instructions in that case.
See this support article for some simple ways to free up storage space.

I have an IMAC and I'm running OSX 10.9.2. I'd like to store my Aperture /IMovie Libraries on an external hard drive. In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives. Is this possible? Can I set up a RAID 5 format for redundancy?

I'd like to store my Aperture /IMovie Libraries on an external hard drive.
That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
You must have backups on a different disk .. otherwise it is pointless.
Can I set up a RAID 5 format for redundancy?
No.. you can buy special USB and Thunderbolt external drives that support RAID..
BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
Raid will corrupt all copies of the files.. it is replicated across all disks.
Delete a photo it is deleted across all disks.. you have no recovery.
Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

I bought a new external hard drive for backups, but time machine won't do a full back up. I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?

I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?
When I bought the new (used) iMac, I also bought an external hard drive for backups. It worked fine, but my husband stole it.
Then I bought a new external hard drive (Seagate) and it worked fine for three weeks, then died.
So I just got a new external hard drive, which was put together from an internal hard drive and a hard drive enclosure.
Time machine did the first backup today, and it should have taken 9 hours like it did on the previous first time full back up. Instead, it took 30 minutes. That can't be right. I want to start over and do a full backup to make sure everything gets onto my new external hard drive, but I can't figure out how to do that. Please help.

Triple-click anywhere in the line below to select it:
tmutil compare -E
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.
