I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

I would like to know if you have to back up a macbook hard drive, can I use a external hard drive that has been previously used to back up several pc 's, or is it best to have a separate external drive for the Mac?

In the Mac side of things, backups usually come in two flavors: clones or incrementals.
A bootable clone is a bit-for-bit copy of all essential files in the startup volume. If using the Lions, clones can be made using CarbonCopyCloner or just plain old Disk Utility. These backups represent the safest protection of your info, but take the longest to do. Recovery is an inverse process: you copy the clone back into the internal drive.
Incremental backups start with a complete backup of the startup volume and only copy whatever changed from the previous run. OS X includes the fully integrated Time Machine backup utility to do this. It is extremely easy to do and takes the least amount of time. Recovery is another matter altogether since you have to start with a freshly installed instance of the OS and have to apply all intervening backups to bring the result to the latest saved version.
As for where the backup takes place, the recommended media is an external dedicated drive or drives connected via the fastest interface available on your Mac: Thunderbolt, USB3, Firewire, or USB2. Network-based backups, wired or wireless, are attractive but may not offer the same performance and hence take longer. Also important to note that the entire drive need not be completely dedicated to a single backup. The Mac's EFI firmware infrastructure allows for an unlimited number of partitions on a hard drive and each can be used for either type of backups.
Holler if you need specifics on how to do each. This was just an executive summary.

  • Hello i would like to know if you have apple shop in birmigham and i want to tell me the cost of iphone 4s because here in your shop i found it 199$ and it is too cheap

    hello i would like to know if you have apple shop in birmigham and i want to tell me the cost of iphone 4s because here in your shop i found it 199$ and it is too cheap

    We're not Apple here, just your fellow users. And you can look this all up yourself:
    http://store.apple.com/uk
    http://www.apple.com/uk/retail/
    A price of $199 would be in the US and would be subsidized by the cell carrier, requiring a two-year contract with them.

  • I cannot and never have been, able to open a file that has been previously saved to hard disk by choosing the print to file option in the print dialogue box

    '''I cannot and never have been, able to open a file that has been previously saved to hard disk by choosing the print to file option in the print dialogue box. Firefox displays gooblygook even though the file name is an html, Windows Notepad crashes, MS Excel does not recognise the file type. MS Word displays goobblys also when the file has no filename extension.'''

    If you use print to file then you get a file that is meant to be send to a printer and that file has all kind of formatting code for that specific printer.
    Opening such a file in Firefox or a text editor can only work if you use a text only printer to print the file to, so make sure that such a printer is installed and selected.

  • I just paid with my visa to increase the size of how much I can store in my iCloud from my iPhone but I'm noticing im going to have to pay the 27.99 price to get what I really want so I would like to know if you can stop that payment or put on 27.99

    I'm sorry I thought I was already doing that lol. Ok so I paid for more storage for my iCloud which was $3.99 but I'm releaizing that im going to have pay the $27.99 payment to get what I want I guess. So I would like to know if that payment can be stopped or forward to the other $27.99 payment I'll be making. I'm also not sure, but think I am lol, that if I were to pay the $27.99 if that applies to my iPhone and my iPad ? Or would that have to be two payments? Which I'm pretty sure its not but rather be safe than sorry. Thanks for your help. All i want to do is to able to store my music in iCloud so I can upgrade my phone to the new iOS 8.1.1 which I'm pretty sure I have room for but I'd rather just pay the $.399 than the $27.99 cuz. I don't need to listen to the radio lol

  • I would like to know if you go into free downloads why cannt you dowloads more than 10 and then you have to pay for them

    I would like to know if the download that are free why cann't you download more than 10 and then you have to pay for them

    If it's free, then it's free no matter how many you download. iTunes might take some time if you download more than three. I have more than 400 apps and a 50 of them are free and I don't have problem.
    Are you sure it was free?

  • I just bought a used XP Home Edition program that has been installed before. Will I be able to install this again on my computer or is it only a one time use software? I have the Product Key and CD.

    I just bought a used XP Home Edition software program that has been installed before. I have the Product Key and installation disc. Will I be able to install it on my own computer? Or, is this software (purchased retail) a one time install? Please advise.

    Depends on many things.
    If your system is Lion, XP can only be installed under VM.  BootCamp in Lion only accepts Windows 7.
    As to "one use only", if you are referring to OEM ...
    A reinstall can trigger the OS to "not register" because "a major component serial number or MAC (the network MAC chip) address" has changed, according to MS databases.
    But you can call MS to get the key reactivated, usually/sometimes.  It is worth a try, at least, before spending money on another Windows 7 package.  But this discussion should end *now* at "maybe" as it treads close to matters that forum Terms-of-Use would prefer we not discuss.

  • Best Anti-Virus/Firewall/Spam Software Suite for the Mac

    What are the alternatives to Intego's Internet Security Barrier dual protection software suite?

    I have to agree with all that has been said. Also - we have found Net Barrier - current version - is worthless - no longer a functional working product. Completely worthless on Leopard 10.5.5.
    Nothing is usefully functional in Leopard - Cookie Filters - Banner Filters - nothing works any more. Hasn't for a long time actually. Waste of time to try an install this product.
    Recently loaded it on a fresh 10.5.5 build - worthless effort.
    The interface is worthless in my opinion - childish and frustrating.
    Virus Barrier - works - Updater is very troublesome. Fails often. And... frankly - a waste of time - just gets in the way!
    Intego Support - non-existent. Unless you count the one time they responded four weeks after a support request was made. Worthless effort! Intego needs to concentrate on their Windows product.
    Now - one product that has always worked for us - never let us down - Little Snitch! Highly recommended!!!! Perfect Watch Dog! Grrrrrrr!
    Mac Scan - also seems to be coming right along - but - the scans are just always a waste of time. Nothing is ever there! Updates regularly! Adds maybe one item! It was free recently or I would not have it installed! It's just amusing to watch!
    As the one commentator said - responsible use and operation is always the best! Always!
    The only Mac infection seen by us to date - the user invited it in the front door and made it comfortable and welcome. Very Dumb! Why sure - here is my admin password too!
    Enough Said!
