Does an external hard drive ALWAYS need to be connected to my mbp with retina display for Time Machine?

Does an external hard drive ALWAYS need to be connected to my mbp (OS 10.10.1) with retina display for Time Machine? Or can it be connected once a week or whenever I want? I used to have an external drive always connected to my previous mbp, but it made moving my mbp around a bit of a hassle with it connected...

When the backup drive is not connected, some of the free space on the internal drive will be used to make local snapshots, which are backup copies of recently deleted files. Local snapshots will protect you from unintended file deletions, but not from a drive failure. You should only go as long between backups as you're willing to lose data. If losing a week's worth of work is acceptable to you, then that backup frequency is OK. Otherwise, it isn't.

I accidentally deleted my media files from iTunes and Trash when I was trying to move the files to an external hard drive. Is there a way to restore the media files from a Time Machine backup or from iTunes Match? What are the steps to do this?

If you have been backing up on Timemachine.
All you need to do is enter time machine... Then the rest is obvious.
Find the iTunes folder and hit 'Restor'.
If not the only way to get all your iTunes music back is to enter iTunes Store.
On the right hand side you should see 'Purchased'.
Click 'purchased' and there you have it.

My hard drive won't mount on 2012 mac book pro with retina display

The flash drive in my Sept 2012 mac book pro with retina display is not mounted, won't mount, and can't be repaired in disk repair. I need files created right before it failed last night that were not backed up. Can they be salvaged before a new warrantied drive is put in at my request? Also is this failure a common problem?

Do I need a film to protect my MBP with Retina Display?

I don't want to change it in at least 4 years. And I'm using it for movie production

I would say no but there may be other opinions. I just clean my MBP every now and then and clean the display with a non-residue cleaner. They look still look good after several years.
Ciao.

I made a bootable disc on an external hard drive, with Yosemite on it. I am running Snow Leopard on my iMac. How can I open the Yosemite disc from the desktop on my iMac? Does the external hard drive need to be connected to my iMac by firewire to do that?

Snow Leopard's Startup Disk pref can’t see Yosemite volumes. So the only way to switch from Snow Leopard to Yosemite is to do what Niel mentioned. Doesn't matter whether it's connected by USB or Firewire, although performance via FW would be faster.
Are you saying that Yos/10.10, as a volume located in a mounted external drive won't appear as an option in Snow Leopard's Startup Disc, in Sys Prefs? I've never heard this one before. AFAIK any mounted volume, regardless of OS, should appear there. I would think that, if it appears in the Boot Picker/Startup Manager it would also appear and could be booted to from Snow's Startup Disk. I can't test this myself, since I don't have Yos. Is what you are saying documented somewhere?

I have a Western Digital external hard drive that needs to be re formatted for use on my iMac, but I do not want to lose existing data, is this possible ?

Formatting a disk always erases all the data on it. Your only option is to back it up elsewhere and restore it once formatted.

Help needed. I have a 3TB external hard drive partitioned into 1TB's. I used one partition as backup for the main computer hard drive. But now it is greyed out as shown in the disk utility and its name changed, i dont know how that happened, i tried verifying and repairing it but had no luck. I also tried mounting and unmounting it but still no solution. Anyone to help please?

Looks bad. I would strongly advise backing up the stuff on the other two partitions as soon as possible in case the rest of the drive goes wrong.
Beyond that, Disk Utility has limited abilities to repair disks, DiskWarrior uses a different approach and might, emphasis might be more successful. It has certainly done the job for me in the past when Disk Utility could not.

IPhoto Library moved to External Hard Drive and need help moving library

Hi - Recently I had my hard drive replaced. I purchased Disk Warrior and moved all files to my external hard drive. Now that my hard drive has been replaced, I'm having trouble moving all my photos back to iPhoto. Nearly all of my 8K+ photos are blurry after I import and enlarge. The ones that are fine have dimensions of or more than 1K x 1K. The digital photos that I moved and are blurry when enlarged are 340x360 (hundreds range). How can I correct?
Thanks so much in advance.

I think I might need to back up ---- So I had a failing hard drive, went to Apple and purchased Disk Warrior. Installed Disk Warrior and tried to recover everything from my hard drive. Then all that was recovered was supposedly moved to my external hard drive. I have now received my computer back with the new hard drive. I plug in my external hard drive and have been trying to move all my images from the external hard drive to iphoto. In both places (external HD and when the photos are imported), the image is at the lower dimensions.
Thanks for your time.

I am looking to back up my MAC, and I need to know how big of an external hard drive I need

I am looking to back up my MAC, and I need to know how big of an external hard drive I need. How do I determine this?

Well, they recommend at least 2 - 3 times the size of your hard drive if you are using Time Machine because that keeps making backups until it runs out of space (and then deletes the oldest to make room for the newest).
However, if you prefer to have a bootable clone as a backup, you need about the same size as your hard drive since it is a perfect copy of your system (unless you want to partition and keep an older clone separately).
So, check to see how large your hard drive is and go from there.

Sorry, but this does not seem to be an iPad question. I'd therefore suggest you ask in the iTunes for Mac forum.

I recently moved my Aperture Library file to an external hard drive. Can I now create a vault to be saved on my Time Capsule for the Aperture library on this external hard drive?

I recently moved my Aperture Library file to an external hard drive. Can I now create a vault to be saved on my Time Capsule for the Aperture library on this external hard drive?

One thing to bear in mind, if you are using Time Machine on your Time Capsule and have it set so the TM backup includes your external drive, you will effectively be backing up your Aperture library twice on the same drive, once with Time Machine and once with the vault. This isn't a problem unless you start to run out of space.
Another thing to note, vaults on network drives used to be flaky (i.e. not really supported) and required workarounds to be able to use them. I'm not sure if this has changed, but I just managed to create a vault on my TC ok.

So I am trying to copy my hard drive "Macintosh HD" to an external hard drive, i want to use Terminal and have tried many ways. For example cp -r /Volumes/"Macintosh HD" /Volumes/"NO NAME". When i do it says No such file or directory. Ideas?

The reason that threadjacking is frowned on (as mentioned in the terms use which you can read by clicking the link to the right on this page) is for the most part a practical one:
By starting your own thread your problem can get individual attention, focussed on your particular set of circumstances.
By joining somebody else's thread it becomes tricky to answer more than one question at the same time, and can lead to confusion for both parties.
So if you don't mind the minor inconvenience, please start your own thread (in the correct forum) so we can get to grips with your particular problem!
