Over the past decade, it has become popular for home and business computer users to store important data and multimedia files on DVDs long-term and as regular data backups. Although significant advances have been made in computer hard drive technology, they still fail. This causes data backups to be even more important. Computer users often try to figure out how to maximize a DVD’s shelf-life in order to minimize the probability of data back-up failure.

What Type of DVD Should You Use?

Although CD and DVD/RW disks can be written to multiple times, they are still significantly less reliable than CD/R and DVD/Rs. This is due to the method used to record and erase data on the read/writable drives compared to single burn “R” discs. R/W disks fail sooner if used multiple times. DVD/Rs on the other hand, require a new disk to be used each time a data backup is done. However, the per-disk cost of writeable DVDs has continued to drop, making them a more affordable data storage solution.DVD Storage

How Many Copies Do You Need to Make?

Ideally, two copies of all important data should be made in case a backup disk fails. Make sure that each copy is stored in two different locations in order to prevent both disks being destroyed due to the storage environments, fire, theft, etc. It is best to use two different DVD brands or an alternate media storage device such as a thumb/portable drive for the second backup location.

Maintaining Cleanliness of Portable Media

A single fingerprint can cause a DVD placed in storage to fail because of the the oils and dirt from the skin of the finger that touched the disk. Do not touch the disk’s surface and store it in a protective jewel case. Many users believe that storing multiple jewel covered disks is a waste of space. However, this helps prevent damage to those disks with data.

DVD Storage

Disks should be stored in the vertical position in order to keep other DVDs or CDs from crushing those at the bottom of a stack. Each jewel case should be taped shut to keep any from opening inadvertently and damaging the disk when moved around. Disks should also be stored in a cool, dark, dry location such as a filing cabinet or infrequently used closet. Direct sunlight and extreme temperature changes have been found to damage optical disks.

Consider On-line Data Backup Solutions

A final backup option for information stored on DVDs is an on-line data storage solution. Many users prefer the flexibility of having information stored on DVD. However, an online data storage service has been found to be a useful second backup storage location, which can minimize the number of DVDs that have to be used.
