Mo Backups, Better Backup
Backup - Types of Mediums
Backup secondary storage mediums is considered when companies' have large amounts of data to store. In the early days of computer invention companies used tapes to backup their data. Today the storage mediums offer tremendous amounts of space for backup. Removable disk packs in the old times store data in capacities of gigabytes to terabytes. The large disks that were used in recent years did not have the ability to rotate and backup was slow as a result.
Today our disks can backup data at speeds of lightning. Floppy disks were used in recent years, however companies that stored small amount of data would use floppy.
Tapes offer sequential-access while some disks will offer random access. Sequential access is the process of going over every file on the tape until it reaches the right file.
Backup - Raid (Redundant Array of Inexpensive Disks)
RAID are disks that have several small disks in parallel to perform the job of the larger disks. When RAID disks are mirrored; files that are written to the drive creates an identical copy and sends it to another drive. RAID offers a quick recovery of data from hard drive crashes and the speed is outstanding. RAID is a great choice of backup and an outstanding source for data recovery .
Backup - Optical Disks
Backup CD's offers users the ability to read and write from disk. Backup such as text, graphics, illustrations and so forth can be written to the disk for backup . The CD densities offers digital images in finer view over many of the other magnetic secondary storage mediums. Optical disks can store in megabytes to gigabytes of backup storage . To use optical disks you must have an peripheral device installed on your unit.
The drive will offer features with the provided software to backup data onto the surface of the optical disks. WORM is an optical disks that allows users to read once and write many. Read once means you can view the data and erase, writing to disks over and over. WORM optical disks allow you to backup for more than a year to the disk. Multisession Capability WORM Disks only) CD-R is probably one of the most widely used optical disk for backup by users.
However, companies' lean more toward disks that offer high-capacity of storage space. CD-R optical disks allows users to store programs, files, photos, software, and operating systems for backup . Music can also be stored onto the CD-R for easy listening.
MO (magneto-optical) disks allow users to erase data or write data to the disk. MO is a combination of magnetic and optical technology that read/writes data. CD PD (Power Drive Disks) is used for heavy-duty random-access applications and is a rewrite disk. CD-RW is also a rewritable disk. The CD-RW can be read on DVD and CD-ROM devices.
Regardless of the secondary storage mediums you choose to back up your mission-critical data, you should always backup . Companies' who value their data will choose wisely when selected secondary storage mediums for backup .
