    I agree he should backkup and archive his data with CCC or similar cloning software, and several people (indludiing me) have pointed to how to do that, but the topic on the table now is dual Time Machine backups.

    3 external hdds connected to a powered usb hub is what i have right now. Like i said, i wanna go wireless.



    How will timemachine backup my library on an external drive???

    I am a fan of 'bundled apple apps'. The integrity of apple apps is awesome and don't wanna be relying on 3rd party apps.

    3rd party APPS?   


    Carbon Copy Cloner is recommended on the Apple forums likely more often than all other APPS combined.

  • hands4 Level 4 (2,220 points)

    OK, wireless.


    Aha.  I did not know you had so many disks.  That could be a lot of storage.  How large is each drive, how much space is used on each, and how large are your TIme Machine backup disks?  Let's see if your USED storage fits on the Time Machine backup disks.


    For each disk volume click on its volume icon then type Command-I to see how much data is in use.

    I can appreciate the significance of ur recommendation but i would still like to use time machine for the ease of use.


    about the disks... they are under 2 tb. a 1tb drive for tm backups, a 320 gb drive for movies, tv shows, a 256 gb internal turned into an external, for developer media and betas.1 tb is for tms for sure. the remaining are used randomly.


    u didn't tell me as to how timemachine will back up my library on the external drive?

  • AceNeerav Level 1 (95 points)

    i just had a thought if i should start using my original apple hdd which was 256 for internal drive again (as i dont really need an ssd, i just bought it out of the hype) and that way be able to store my entire photo collecetion internally, and, get the highest capacity time capsule and store tm backups on it? cause a 3tb time capsule is $400 which is same as a 4tb RAID 1 nas from LACIE. but then time capsule is also a state of the art router and can take in one more hdd connected to it via usb. plus i can convert more hdds to nas drives via nas adapters.

  • AceNeerav Level 1 (95 points)

    can someone tell me if its possible to attach more than one usb hdds to the us port of the time capsule via a powered usb hub?! just wondering. cause that would also eliminate the need of a nas adapter! and the best is i can put to goo use all my current hdds!

    u didn't tell me as to how timemachine will back up my library on the external drive?

    Yes.  We are assuming Time Machine as the only backup software.  You have been clear on that.


    Sorry I was not clear on backing up your photo library.  Time Machine will backup all of your external drives, unless you exclude one or more of them. So it will backup your external library.  It will just do it.


    Let't go back to counting what you want to backup and what you consider temporary storage that you can afford to lose.


    You are clear you want to backup your internal SSD and your photo library disk.  If the other disk with movies and TV shows do not need to be backed up (if you can afford to lose them) then you do not need a huge Time Machine disk.  How large do you expect your photo library to grow to?  Add that size to your 128 GB SSD, multiple by 1.2 and then that is the size of the backup disks you need.  Will that fit on 1 TB disks?  If not you need 2 or 3 TB backup disks.  (4 TB disks are not yet reliable enough.)  Hopefully you will have a lot more space than 20% extra, but that small amount of headroom will do.


    So if you have temporary data on an external disks, just tell Time Machine not to backup those disks.

  • hands4 Level 4 (2,220 points)

    Yes.  You can attach multiple drives to any generation of Time Capsules via a powered USB hub.



    If you do that you can use one of the external drives as your second backup drive.  It might as well be a 3 TB drive.  This will allow you to backup your internal SSD, your external photo library, and other disks you wish to include in the backup, as long as the total disk USED to be backed up does not exceed about 2.4 TB.


    Again, what are the sizes of the USED space on your external hard drives?

    How do u manage backup?

    I've never used Time Machine - for me, it's overkill.


    Instead, I make a complete bootable clone of my hard drive every day, and sometimes more frequently than every day, with Carbon Copy Cloner, to an external hard drive.


    Additionally, once a week I make another clone, to another external drive.

  • hands4 Level 4 (2,220 points)



    Yes. CCC is a great option for backing up drives and that has been discussed in this thread but it requires more effort than Time Machine.  AceNeerav is clear he wants the automated simplicty of Time Machine.

  • macjack Level 9 (50,735 points)

    TM backups are not as reliable as cloning. I'd only use TM as a secondary backup. The simplicity of CCC or SuperDuper is almost equal to TM.

  • hands4 Level 4 (2,220 points)

    I agree, mostly.  Time Machine is plug and play to backup multiple disks.  CCC requires one to schedule backups or do them manually and to have one cloned disk for ever disk in use.  It requires you to purchase a 3rd party appllication.  CCC does not maintain hourly snapsots and is not available from online when you need to restore from a snapsot.  All of these are only minor points and I too find CCC to be easy to use.

  • Tom in London Level 4 (1,610 points)

    Effort to use CCC? If it required effort I wouldn't do it!


    I'm kind of a lazy guy but even I can just about manage the "effort" required to use CCC:


    1. Insert USB plug into USB socket.

    2. One click to start up CCC.

    3. One click to select the main drive.

    4. One click to select the target drive.

    5. Type in user password.

    6. Go and lie down in a darkened room for about 10 minutes while CCC clones my drive.


    Oh boy - I'm exhausted....
