【 Weak current College 】 SME use of tape backup and restore of analysis of the advantages and disadvantages

Beginning from the hard drive prices lower than the price of tape start, enterprise-class data storage industry in the past decade has undergone significant changes, however, the tape in many companies of backup and restore functionality is still saved its original position, particularly in small and medium-sized enterprise environments of use.

Use a tape backup or tape library has many advantages. For example, for backup tape library can be removed and then secure stored in locations far away from the data center. In addition, the tape is often used to restore the hard drive is lost or other disaster caused by the hard drive will not work. Tape can withstand some special circumstances, such as flood or other disaster, and the hard disk in such an environment will result in data loss. In addition, if encountered an unexpected disaster, tape restore services can clean and dry the wet tape, and then try to restore the original data stored on it. In this article was previously published under painted, we will understand that tape storage advantages and disadvantages of skills, as well as today's leading tape data storage skills, but also touch on tape storage skills in data secure sexuality is how to deal with the topic, and tape costs or more.

Summary: this paper tape storage skills in SMEs environment utilizing the advantages and disadvantages of

Tape storage capacity is usually less than the hard disk storage capacity

Today's mainstream tape data storage skills

SME environment in tape storage backup skills need to be thought of elements

Tape storage media life

In safekeeping, tape storage media of the longest life expectancy is about 30 years. In addition, many tape storage equipment have backward compatibility. For example, a 20-year data on DLT tape, perhaps now the DLT tape can also be read out. The 1980s can read nine tracks of tape on the strange can now also read out. Although many advanced tape format in today is able to provide good support, but now the tape in a number of years there can still be read.

Hard drive interface of life and tape together maybe not such a long life. Advanced for the 1980s that capacity is small, made by MFM or RLL hard disk as a interface hardly find the corresponding PC or the corresponding interface, in today's perhaps could not be read. Parallel ATA is well-known IDE interface hard disk now has gradually beginning in the market is no longer used, but the advent of twenty years of SCSI and later out fibers interface hard drives in the market also stays for a period of time. Serial ATA (SATA) interface drive is the latest popular products, to the current date it can be used to support capacity

Up to 2TB, as a result of new product comparison, it on the market will exist at least ten years. All in all, if it is thought long storage of data, or for those who have long-term storage of data for a successful restore, the tape will be the best choice.
