    I have an iMac which backs up through Time Machine onto my Time Capsule. I want to make an additional backup onto an external hard drive just in case anything should happen to my iMac or Time Capsule. I would probably do this maybe once or twice a month.
    Should I copy & paste the Time Capsule file or do a Time Machine backup onto the external hard drive?

    Thanks in advance for you help.

    Get Carbon Copy Cloner or SuperDuper and Clone the HDD.

    Thanks for the response, just to go back to my request would either way I mentioned be possible or would I run into any problems that you could see?

    I have a similar situation. I have a 2 TB Time Capsule and attached to that I have a 2 TB USB Disk (Airport Disk). So far I have used the archive function on the Time Capsule to duplicate everything to the Airport Disk. I have only done this once (so far) so I am unsure what happens if you choose to archive again......i.e., does it make a new fresh archive or does it make an incremental archive. Maybe this is something you can use. I still need to experiment with CCC or SuperDuper in this setup.

    There are some advantages of backing up the Time Machine backup. The Time Machine archive has different versions of files, along side a full copy - which is useful. The problem is that the archive isn't bootable - and I've also found problems in the past making a good backup of all the hard-links used by Time Machine. It doesn't seem to be the most resilient of backup formats.

    I would instead do as McGiord suggested and make a bootable copy using CCC or SuperDuper!

    It really is incredibly useful to have a bootable version - it's a much quicker way to recover if you experience a crash.

    Consider keeping a copy off-site too.
