Backup - Secondary Storage Mediums
Secondary storage mediums are designed to backup mission-critical data, storing files on its disks.
Still, data on backup disks can become lost and a recovery plans need to be set in motion. Backup storage mediums should be kept in a safe environment away from dust, heat, static, and other contaminations that can cause data loss. Before backup your files, your should consider space reduction and security. Compressing your files before you back them up, will save space and add needed space for t extra backup. Encryptions used in backup processes will protect your mission-critical data.
Backup - the Right Space
Backup disks are great for storing data, but if you have a large loads of data, other options should be considered before purchasing secondary storage mediums. The new optical disk on the market today can store terabytes of storage data. RAID (Redundant Array of Inexpensive Disks) can store large quantities of data, and send data to separate disks attached to its surface if the first backup fails. Hard disk supplies huge and swift secondary storage space than common diskettes.
A hard disk consists of one or more rigid platters coated with oxide material, which enables files to be magnetically recorded on the disks surface. Most hard disks however are mounted inside your computer and can not be moved like diskettes. Hard disks if you store data on one drive, two surfaces will be obtainable for storing data.
Backup - Access Time
Hard disks access time is between ten and twenty milliseconds. This means that hard disk is faster than backup disks, CDs, or diskettes. Hard disks spin ten to twenty times faster than backup disk drives. The storage capacity of hard disk drives is measured in megabytes. Some computers have hard disks that can store billions of bytes of data on its surface. Hard disk read/write heads are attached to what are called access arms that swing over the disks surface reaching the correct track.
Data is usually organized in one or two ways on a hard disk. The sector method is comparable to the disk method. The disk surface is divided, while the cylinder method- all tracks of the same number on each recording is considered part of the same cylinder.
Backup disks are economical, however you must ensure disk protection and security once you have backed up your data to disks. If you chose automatic backup features for disk, CD programs, tapes, or RAID be sure to select the disk that will provide the right amount of disk space. In many cases people forget to backup mission-critical data and their failures lead to disaster. Automatic backup offers solutions to all backup needs, including recovery.
Third-party software or Iomega products offer automatic features for backup , as well as recovery tools. The sophisticated software's available today can offer features for business continuity. Features such as, easy access to data, security, space reduction, and application availability. The features can provide companies' a long-lasting business environment.
