I finally got this 'Time Machine' to work, & am now regretting it; it's been on ALL NIGHT; ALL DAY; and is telling me it still needs to take another 12 hours?! This is insane. This is the first back-up, but I omitted all my photos from the back-up, so it is ONLY backing up around 59GB; this cannot take 48 hours, surely?! I've been previously backing up photos manually by dragging & dropping & have already copied across around 58GB to the hard drive in just a few hours. Is there something wrong with it? Will it ever finish?

 

What will happen if I just stop it; will all of the stuff it's copied so far vanish? Or can I re-start it & it will simply finish off where it left off?

 

Apart from anything else I really do not like to leave my computer on for this length of time!

iMac, Mac OS X (10.7)

    Are you doing your backup wirelessly? It will go much faster connected by Ethernet cable.

    Is the USB ExHD formatted for Mac OS Extended (Journaled)?

    The first back-up is always the longest, though yours seems excessive. USB can be slow though. RRFS makes a good point that your back-up should be in the correct format. I would say let it finish is possible, and if subsequent back-ups take a long time then reformat the back-up drive and start over. Something seems amiss.

    Most hard drives are shipped in a Windows file format. Mac OS uses a very different file format and can write to a FAT32 (Windows) format but it takes time and it won't read it well. New drives for Macs should be erased and reformatted for Mac OS and you should never install the junk software that manages the drives as it will typically cause problems down the road. Open Applications > Utilities > Disk Utility and highlight your drive and then find which format you have on the drive.

    He is not talking about the format of the files, but the format of the hard drive volume. Many drives come pre-formatted for Windows (guess why) and while Macs will read and (usually) write to those formats it will work better if the drive is formatted to be used by a Mac.

     

    To do this, open Disk Utility on the Mac (found in /Applications/Utilities) and select the external hard drive. Go to the Erase tab. What format is selected below? If it is Mac OS Extended (Journaled) you don't need to do anything, but if something else, select Mac OS Extended (Journaled) and then click the Erase... button.

     

    It only takes a few seconds to erase.

    Mac OS Extended (Journaled) is a HD format specific to OSX. Others can be used, but I believe Time Machine requires that one. I recently started using Time Machine as well and assure you that it is not useless. Before that I back-up using a drive mirroring program named SuperDuper! that is great for backing up your entire drive as a bootable disk. I still use it since I've found redundancy to be important.  Anyway, I bout a WD hard drive and reformated it using Disk Utility before starting to use it with Time Machine. The first backup ran overnight, but the subsequent ones are fairly speedy.

    Here is the very best tutorial for Time Machine:

    "I also do not understand this business about it keeping several different back-ups 'until the hard drive is full'; why would it keep copying the same things? I only want one back-up copy of all my files."

     

    I don't believe it copies the same files over again. Rather I think it copies different versions of the same files. This is in case you need to return to a version of a file that worked properly or had not been edited after a certain point. Believe me, this is a handy feature, esp. for people that write and have different versions of a specific file.
