What is a suitable fuse

If the previous article "How to create what they have learned to specific software to backup using backup cost is to be read manually. Another problem is the different materials and is suitable for different backup strategy. Discuss in this article we are the most important is to save and protect the balance of the media, reliability, ease of use, comfort and price.

Tape

Strip was introduced in 1960 is a big step forward compared to just punch cards and hard disks. Because of its low cost, convenience and scalability of tape backup is still possible for some companies. However, it is inevitable in history: a backup solution for most companies today do not support tape drives that are not included in the backup software at home.

There are some problems with the tape. First, it is very reliable and copies stored on them to study very hard. Statistically, it is never 34% of the companies testing the backup tapes, and those errors were 77% of various types and sizes. This allows you to save only of all necessary documents and information to determine what has changed almost impossible. Finally, transported and stored in a special room for the mild conditions.

External storage media: hard disk (including external hard drives, USB, FireWire and flash drives)

Data backup to another hard disk or RAID (redundant series of inexpensive disk) is a good choice if you always want to backup. One of the biggest advantages of cloning the hard drive is that if the primary hard drive is simply connected to the others and continue without delay. However, an external backup drive does not protect against theft and fire (unless the town is saved always present.) In addition, external hard drives price much higher than the price of the DVD packaging, for example.

Optical Discs

CD and DVD media, one of the most popular and reliable in use. They are compact, inexpensive and make a sufficient capacity for regular backups. In most cases the 700 MB and 4.7 GB DVD disc to store a copy, the new information in a few days or weeks (depending on your computer). To make matters worse, when you back up huge amounts of data (eg backup disk) want the new numbers and accounting, but can be very boring. What is the sensitivity of one copy of the DVD, which is identical to the hard disk: optical media in general in the vicinity of the unit that protects data from fire and natural disasters.

Another frequent topic of discussion on the next generation of optical discs or Blu-Ray and HD-DVD. Very promising in the backup can be up to 100 GB of data. However, the recording devices are not yet widespread, and there are no statistics to back off.

Remote Storage

The basic idea of remote backup data from remote computer, which can not for the disasters that occur on the sides, not applicable. Today, many online backup services, the storage space on your hard drive (or, more generally, to rent a storage type system), to ensure complete security. Some of them offer space and remote access to them, others are backups for easy data management. In general, remote servers, which are known to be the safest and most reliable supply, but at the same time, the most expensive storage space.

The choice of locations to store information on a simple rule: "The most important information should be maintained reliably. For example, the combination can work well: writing a weekly system backup external hard drive and move documents on a daily backup to a FTP server. When planning a backup plan to ensure backups are regularly performed and data are protected against all risks.
