Mac backup hard drive to dvd

A Plan B or Plan C user might be able to get by with DVD-R backups in a pinch but that means he or she will have to be present during backups to swap discs, which may be unacceptable. Bulk, cheap DVD-R media can be very flaky. One last thing: If your drive supports both plus and minus, feel free to purchase whichever flavor you can get the best deal on. If you bought your Mac in the last few years it's likely you have an optical disc burner known as a "SuperDrive" built into your Mac. If you're not sure what type of optical discs you can burn on your Mac, launch the Apple System Profiler application it's in your Utilities folder and click on Disc Burning in the Contents column as shown in Figure Click on the thumbnail for a larger image.

Also, if you're going to do incremental backups on a DVD-R, your backup software must support the burner. Without this compatibility you can only burn a disc in one session; with compatibility you can add to a DVD-R disc in multiple backup sessions, a feature you almost certainly want. I have a pile of them in my cupboard. Larger capacity MO drives are available but are more expensive, so for the sake of this discussion we'll limit ourselves to the 1. One of the best things about MO cartridges is that they're nearly indestructible. If you're hard on your media, and often drop stuff on a hard floor, MO may be a good choice for you.

An MO drive can also serve as an additional 1. Tape is the holy grail of big backups.

Each uses a slightly different mechanism and requires slightly different tapes. Tape drives are less versatile than any of the devices discussed so far. Unlike the others, a tape drive can't be used for anything but backups.

Commercial DVDs

In other words, you can't copy files to a tape from the Finder and you can't open a file directly from a tape. Still, if you have big backup needs, there's nothing like backing up two or three hundred gigabytes of data to the one tape. The biggest advantage of tape, for most people, is that backups can be performed "unattended" i.

But tapes have a dark side. My experience is that tapes don't maintain their integrity over long periods of time; they last a few years at best. After a few years, tapes tend to develop errors, which can render them useless. That's because, unlike optical discs, which use lasers to record your data, tape drives use magnetic tape heads kind of like a big audiocassette recorder. Which basically means backup tapes are subject to the same idiosyncrasies as audiotapes: They deteriorate over time and are particularly sensitive to temperature extremes and magnets.

This is yet another reason Rule 1 one backup is never enough is so important. Also, the heads on tape drives get dirty and wear out, which can damage a tape beyond redemption.

Backup Files, Partitions, and Drives to DVD/CD

So I only recommend tape for short-term backups. In other words, if you think you are going to need data from a tape 5 years from now, I strongly recommend you also back up that data to a more permanent media such as CD, DVD, MO, or hard disk. I recommend a combination of tape and another media such as DVD, MO, or hard disk for Plan C users who want their backup data available both tomorrow and several years from tomorrow. A tape drive is way-overkill for a Plan A user, and probably too expensive tape drives cost more than any of the devices listed so far for Plan B users.

But they're great for the serious Plan C user who doesn't want to hang around to swap discs during large backups. Drag each of the files you want backed up from your system from their location on your hard drive to the external hard drive's disk window. To organize content in folders, click the drop-down menu on the external hard drive's window and select "New Folder" to create a new folder: Close the external hard drive's disk window once all files have safely been transferred to the device.

Make certain that no files are still in the process of transfer before you close the window.

Drag the hard drive's icon from the Desktop to the Trash bin to safely eject. Connect an external hard drive to the computer using the USB cable and wait for the drive's icon to appear on the desktop. Hold the "C" key to start the system from the disc.
