Help on what program to backup my Mac?
I'm really confused about backing up files to an external hard drive, I have a Mac, and when I connect my external hard drive to the computer it tells me if I want to backup my Mac with Time Machine, but I don't know what it's the best thing to do.
I want to use my external hard drive like an usb. I don't want to backup all my Mac, but a bunch of videos that I'm scared to lose if my Mac chrases someday. How should I backup it? Is there a way to just selectively drag the files into the external hard drive (Like an USB). I tried by opening the file of the external hard drive and dragging the videos to the drive but it doesn't work. Also, what I may have to do is backup the videos and delete them from my Mac afterwards... (it takes up almost all my space). I'm sorry, I'm just very confused about everything. _____________________________________ I was searching on how to manually just drag my files to the Hard Drive and found out that the reason I cant drag the files is because the Hard Drive is formatted NTFS (which means you can't add files to it from your mac.) what can I do?

Then there is CarbonCopyCloner (free version 3.4.7 not officially compatible with OS X 10.8 Mountain Lion though) and SuperDuper!, which are applications, that clone (create a 1:1 copy) your internal HDD to an external HDD. With those two applications you can select what to copy and what not to copy (more advanced than Time Machine), the process can also be scheduled for a daily backup (Time Machine runs hourly). The advantage of a clone is also that it is bootable, which means, if your internal HDD gets corrupt or Mac OS X does not boot, you can boot from the external clone (if you have not deselected files/folders that the system needs). Time Machine might be the best solution out of those three if you are not that technically savvy. * Time Machine FAQ Quote:

Your HDD needs to be formatted appropriately, HFS+ (Mac OS Extended) being the best, if all you want to do with the HDD is use it with Mac OS X. Quote:

I have one 500 GB HDD for my photographs (digital and analog) libraries and editing documents, one 500 GB HDD with my personal video footage in an editing friendly format. Both 500 GB HDDs get backed up to one 1 TB HDD via CarbonCopyCloner. And that 1 TB HDD gets backed up to another 1 TB HDD via CarbonCopyCloner. Therefore I have three copies of my important data.

Thanks sim for all the good info. I have similar questions with my new iMac and that answered a lot. One thing I haven't found yet.. Can I use clone with SuperDuper and use Time Machine for backup to the same external HDD or should I have my clone on a separate partition than Time Machine? Is so, any idea how large a clone can be? Is it a compressed format? I have the 1TB Fusion drive. Thanks again.

The TM backup and the clone backup are at maximum around the size of the data you want to backup, say you have a 1 TB primary drive and have 256 GB of it used, around 256 GB will be backed up via cloning and Time Machine (if nothing is excluded).

That makes sense. I asked about the sizes because the Time Machine FAQ you linked to states:
"A general "rule of thumb" is, Time Machine needs 2 to 3 times as much space as the data it's backing-up (not necessarily the entire size of your internal HD (and any other drives/partitions you want to back up). " Using EaseUs Todo backup on my PC laptop and creating incremental backups at high compression rates has left my with backup files much larger than the original file source. I always thought this was just a problem with the software but after reading that FAQ I thought Time Machine might work in a similar manner. Thanks |

). If I delete or lose an important file I can recover it from the Time Machine. My cloned backup runs nightly, and allows me to recover from catastrophic hardware errors... like the hard-drive crashes. However - there is a another recovery option besides from a hard-drive failure. If your entire computer goes into the shop, you can use your cloned backup to boot a 2nd Mac computer. This computer will then have all of your documents, applications, settings, etc. In other words - within the limitations of the hardware this 2nd computer becomes the computer that is in the shop, and you can carry on with your work. I used this to boot a Mac Book Pro (a laptop) as a backup computer when my Mac Pro was in the shop. When the sick computer came back I simply copied the external HDD to the internal HDD to bring it up to date... It is not perfect - some applications are licensed using the hardware for instance, and if it is a USB external HDD the boot times can be brutal. But... for the most part it works really well to keep you working when you would otherwise be stuck. Quote:
