Storage capacity

Zip disks have a storage capacity of approximately 100 to 250 megabytes. While suitable for quick incremental backups of smaller files, they are highly impractical for medium and large-scale backups. It is more efficient to consolidate backups onto a greater-capacity storage medium instead of "spanning" them across multiple Zip disks.

The size of the disk is important: Zip 250 disks can only be read by a Zip 250 drive. Zip 100 disks can be read in either a Zip 100 or a Zip 250 drive. Be sure to check your Zip drive's model before purchasing media for it!

Reliability

Although somewhat sturdier than floppy disks, Zip disks suffer from the same complications as their older cousin: corruption caused by dust, humidity, magnetic fields, and physical damage. If you must use Zip disks to backup files, it is advisable that you make at least one duplicate in case the original backup Zip disk becomes unusable.

Performing backups

1. Insert the Zip disk into the drive. Usually, this drive is designated by the letter "D", but the letter may differ depending on the other drives present.
2. Copy files to the Zip disk in one of two ways:
• Highlight the files with your mouse and drag them to the Zip drive.
• Right-click on the files and choose "Send to Zip drive".
