Is it possible to sync time capsule data to a external hard drive

Is it possible to sync time capsule data to a external hard drive connected to time capsule via usb. (as an precaution just incase time capsule fails)
Thanks

Yes, if the USB drive has been previously formatted correctly in Mac OS Extended (Journaled) format.
Open AirPort Utility - Click Manual Setup
Click the Disks icon
Click the Disks tab below the icon
Click Archive
Allow plenty of time for the copy process to occur. You will not be able to make Time Machine backups from your Mac until the Archive process has completed.

I transferred data from my external hard drive to my restored Mac Book Pro via migration assistant and now my external hard drive in time capsule has red minus signs. How do I get rid of that without getting rid of any of my data?

I used Migration Assistant to transfer my data from my external hard drive via Time Capsule to my restored Mac Book Pro. When I now go into Time Capsule I there are red minus signs in the corner of all the folders that are contained in my back up. How do I get rid of this and access my previous back-ups?

Select the drive and Finder > Get info and at the bottom "ignore permissions on this volume"
You can copy the files, but the ownership on the files still belongs to the other user account, once your done copying, then perform a #6 Reset Users Permissions and that will set all the ownership to that account.

Another method is to copy the entire folder, then change it's permissions.

I cannot transfer data from my external hard drive to my new mac

I had to get a new hard drive put into my macbook pro because it was failing. So, I moved all my data onto an external hard drive so I would not lose anything. But now I cannot get iphoto or imovie back onto my computer. It says I cannot open it because it is a time machine back up. I don't want to have to purchase iPhoto and iMovie again just because I had to replace my hard drive.

Copying the files directly from a Time Machine backup may be possible but I don't recommend it. Your new hard disk is essentially a new computer to Time Machine, and it will have problems understanding where to put the individual files. What you're trying to do is just not the right way to go about it.
To restore from a Time Machine backup, boot Lion Recovery and select "Restore from Time Machine backup".

How do i recover data from an external hard drive that was accidentally deleted? After I verified the drive, a message appeared that said my drive needed to be repaired. When I tried to access the drive again, the 700 Gigs of music is gone!

Stop using the drive immediately, un plug it.
Buy a copy of ProSoft DataRescue 4 and use it to search for deleted files.

HT1751 when i have moved all of my data to an external hard drive should i delete all of the library files on my laptop/PC

i have moved all of my data to an external hard drive should i then delete the copies on my laptop

What are you actually trying to accomplish? Backing up the library, or moving it?
If backing up don't delete anything.
If moving did you move the library files as well? Ideally you would copy the entire iTunes folder out to the external drive then shift-start iTunes to connect to the relocated library. This method makes it easier to move the library to a new drive or computer later and keeps everything together for backing up. Rather than delete everything rename the iTunes or iTunes Media folder first (depending on which approach you took) and make sure the library still works before deleting.

How do i retrieve data from my external hard drive?

how do i retrieve data from my external hard drive?

If your hard drive can be detected and shows up as a drive letter in my computer but you can't access your files,then you can recover your data off it with data recovery software easily.This way is the easiest and the most inexpensive way to recover your data.If you bring it to a computer repair shop that is available for data recovery servise,they will cost you $500-1000 or more.Hmm, a lot of money.
I managed to recover data from crashed hard drive with Tenorshare Data Recovery.If needed,you can download it and scan your hard drive for free to preview whether your data can be recovered.It will show you thumbnails for recoverable pictures.

I'm having some difficulty with Time Machine. It appears to be deleting backups from random dates on my external hard drive. I am not deleting them. Are they hidden and how do I prevent this from happening? Can I retrieve them?

I'm having some difficulty with Time Machine. It appears to be deleting backups from random dates on my external hard drive. I am not deleting them. Are they hidden and how do I prevent this from happening? Can I retrieve them?

... I didn't know that Time Machine was more a last resort back up instead of main back up.
Don't rely upon Time Machine to the exclusion of all else. I compliment Time Machine with a periodic "clone". TM is much better than nothing, but it's a safety net, not a hammock
Here is my understanding of Time Machine's file deletion algorithm, distilled from Pondini's FAQ, Apple's KB articles, and my own observations.
Time Machine deletes ("thins") files from the backup disk as follows:
Hourly backups over 24 hours old, except the first backup of the day
Daily backups over 30 days old, except the first backup of the week
Older backups get deleted when Time Machine requires space and you deleted them from the source disk.
Therefore, assuming TM has been performing at least one backup per day, backup files will remain available:
at least thirty days, if they existed on your Mac for at least a day
until you run out of space, if they existed on your Mac for at least a week
In addition to the above, Time Machine always keeps one complete copy of your source disk so that the entire volume could be restored if necessary. Any files that remain on your source volume will be present on the TM backup, no matter how old they are.
If you are using 250 GB of space on your source disk, its Time Machine backups are likely to require at least twice that much. A good estimate of the minimum required backup volume size would be about three times the size of your source disk - 1.5 TB in your case.
A more thorough explanation would require Pondini since he has plumbed Time Machine's mysteries far more than I have.

Hello, Esmin77.
Thank you for visiting Apple Support Communities.
I see you want to restore your MacBook Pro from an external drive. Here is an article that may help you with this process if you used Time Machine to backup these files.

How do I transfer data from one external hard drive to another larger one?

I hope I am posting in the logical area for this topic. I have an external hard drive connected to my eMac. My iTunes library and some backup files reside on this hard drive. I am contemplating purchasing another, larger external hard drive so that I can archive more data--more music and some photos. How do I transfer my data from the first drive to the second one, and is this a risky move? (I have a lot of music!)

Hello,
Take a look at SuperDuper (link). This 'clones' any drive across to another; it should suit your needs just fine.
Firewire drives with an Oxford chipset are recommended for PowerPC Macs (like the eMac and iBook) as you can boot the Mac from one to recover the system if the internal drive suffers any issues.

Can I restore settings, apps and data from an external hard drive to new Macbook Pro?

I recently lost my Macbook Pro to water damage. It was about 3 years old and tuned for comfort. Unfortunately, my most recent backup is at least 3 months old. I purchased a new MacBook Pro and I'm wondering what my options are for migrating my settings, apps and data from the old hard drive to the new MacBook Pro? I have a USB drive bay that I plan to attach to the new MBP to gain access to the old hard drive. Someone suggested Migration Assistant but my research hasn't turned up any information about migrating data from an external drive.
Any help would be greatly appreciated.

THANKS! I guess my research wasn't THAT thorough. I booted with the external drive attached and setup immediately gave me the option to setup using Migration Assistant. It was a little slow via USB (2+ hours) but it was nothing compared to the time it would have taken to do it manually. My new 15" MBP looks exactly like my old 13" MBP. AWESOME!!!
Thanks again!

How to recover data from an external hard drive that has lost half of the data I was storing in it

I am using a Lacie external hard drive to store my photos on. Every once in awhile it disappears from my screen. I have been able to bring it back by unplugging and re-plugging from the computer. Then I had to turn it off and on again. Finally, it lost about half the stored photos, and I couldn't recover them. Does anybody have any suggestions as to what I might do to fix this problem?
I'm using an iMac with iOS 10.6.8
The hard drive has 1 TB capacity

Moving data from one external hard drive to another ERROR-36

i got a new hp simplesave external hard drive, and i'm moving all my files from an older external hard drive (can't find brand name). Some of the files are bringing up error 36 which is something along the lines of can't read/write file. which is causing the file transfer to stop on that one file. there are a lot of damaged files so the file transferring is going very slowly. is there a way i can find out which files are bad ahead of time so i can get rid of them AND THEN transfer the files?

Well, since the MacBook with Tiger still has issues with the drive, I think it is some kind of hardware problem related to the external drive. I have numerous USB and FireWire drives connected (probably too many), and I've had no issues with Snow Leopard. Snow Leopard makes my older Intel iMac run better than when it was new.
Make sure you try connecting the drive to a separate power outlet, if it is connected to a power strip. It is also possible the drive's power supply is failing; that can cause the the improper disconnect message to come up, because the drive inside is not getting sufficient power. That is why you need to try the hard drive in a different case, or using the USB adapter, to eliminate possibilities.
Also, I still don't know if this drive is USB or FireWire, but be sure to try it with no other devices connected, in case there is some interference between devices.
One more thing you can try to rule out a problem with your currently installed system. Start up using the Snow Leopard installation disc; insert disc and restart with the C key held down. When you get to Installer's first screen, go up to the menu bar and, under Utilities, select to run Disk Utility.
At this point, you can just leave the iMac alone for a while to see if the drive gets ejected. If it does not, try making a Disk Image of the external drive and saving the image file to the iMac's internal drive. If that works, there may be some issue with your current installation (and you have a backup of the data). If it fails, then I think you have confirmed that the problem is with the external drive, not the iMac or Snow Leopard.

How to archive "sent" mail to external hard drive

Accumulated and overload of "sent" mail and would like to archive them all (including attachments) on my external hard drive. Would someone give me the steps to do this, as a regular archiving procedure, as done with a mailbox, did not work. Thank you.

You can navigate to your Sent (mailbox) folder and drag and drop it to another drive.
First remember how many messages there are in the Sent folder.
Then navigate as follows to get to the folder:
Users / yourself / Library / Mail.
At this point you will see a number of folders. Look for the one that identifies your service. Something like: POP-yourname, ....
In that folder look for Sent Messages.mbox. In there look for a folder called messages. That's where all the sent messages reside. Verify the number of messages there agrees with the number you originally noted. That is to confirm you have indeed found the correct folder.
This, like any other folder, can be copied to an external drive, or whatever.
The problem with this process is that each time you do it, you will be copying over a bunch of mails that have already been copied.
Note that all of the above is on the assumption that you are running OS 10.6.8.

Data transfer to external hard drive

I have an iMac running OS X 10.9.2. The problem I'm having is that my hard drive is full - mostly due to HD home videos that I have saved to iMovie. I need to move them to an external hard drive in order to free up some room. I really would like to put them (2 copies of the same videos) on 2 separate hard drives, so that I will have a back-up in case one fails. I am not really that mac savvy - so I was wondering if someone could tell me the best/easiest way to go about doing this. Where I get hung up is if I move it to one drive, then it's no longer on the mac - so how do I put a copy on a second drive?
Any help/suggestions would be greatly appreciated!!
Thanks!

You are copying a file from one drive to another, not moving it. The file will still be on the Mac from which you copied it.
Select all the movies you wish to copy. Then drag your selection to a folder on one of the backup drives. Now drag that same selection to the second backup drive. When the copying is completed you will have two backups. You can now delete the selection from the startup drive.
Freeing Up Space on The Hard Drive
1. See Lion/Mountain Lion/Mavericks' Storage Display.
2. You can remove data from your Home folder except for the /Home/Library/ folder.
3. Visit The XLab FAQs and read the FAQ on freeing up space on your hard drive.
4. Also see Freeing space on your Mac OS X startup disk.
5. See Where did my Disk Space go?.
6. See The Storage Display.
You must Empty the Trash in order to recover the space they occupied on the hard drive.
You should consider replacing the drive with a larger one. Check out OWC for drives, tutorials, and toolkits.
Try using OmniDiskSweeper 1.8 or GrandPerspective to search your drive for large files and where they are located.
