What is the best computer backup system?

The computer backup system is paramount when home computers are approaching the terrabyte border. The reconstruction of the operating system itself can be time consuming, although data files have been archived for compact discs or other media. The best computer backup system for individuals depends on many factors, including personal needs, preferences, skills and financial considerations.

external, magnetic tape units provided an affordable back at a time when it was an alternative to floppy disks or later compact discs. Although most tape units are still widely used for network backup, it has extremely slow access. With the falling price of hard drives and more convenient alternatives, the magnetic tape unit becomes an inheritance and is not the best option for home users. The disk image is one large, compressed file that takes up much less space than cloning or copying. The disk image can buffed with anywhere, even on the primary unit, and toWhen it's not the best place. It is safer to lay a disk on a secondary or external unit. In the event of a primary disk failure, the image can be used to restore the system on a new hard drive.

The

advantage of the disk image is that it consumes a relatively small amount of space. The disadvantage is that it cannot be directly accessed, but must be restored to the software that has created it. This can mean introduction from a proprietary CD to access the recovery process. Although this procedure is not complicated, it may be a little nervous confusion to "jump over the hoops" to convert the system.

Better computer backup system deals with a secondary hard disk as a clone for the primary disk. If the primary disk fails, instead of a secondary disk. No restoration, no downtime and no problems are required. Simply bootable ride and go about your business.

Software as popular acronis ™ can runm for a few minutes to clone the primary disk on the secondary disk. The secondary disk can be installed internally or can be placed in an external cover. In the event of a disk failure, a desktop computer or laptop has the ability to introduce an external device from the use of an external (or secondary) unit until the unsuccessful drive is replaced. At this point, the outer unit is cloned back to the new primary unit.

A nice thing on this computer backup system is that there are no hoops that would take place, and you don't have to wait for a replacement unit that will continue to work. Your clone is ready from the moment the main unit fails. If the secondary unit is located externally, you can also keep it in a safe place as a focal point, locked in safe. The disadvantage of using this computer backup system is that a new disk must be purchased and the whole print must be reserved as a clone.

Another solution that uses two discs (minimum),is the raid or redundant field of independent discs. Both units are installed internally, which makes it only for desktop computers. RAID has different flavors or methods of functioning, referred to as RAID 0, RAID 1, RAID 2, etc. RAID 1 is a mirror technology, which means that everything that is written on the primary unit is written simultaneously on a secondary unit that maintains a constant duplicate or a mirror of the primary drive. If one of the drives fails, it is replaced and the mirror unit is copied to a replacement unit.

The advantage over the previous computer backup system is that both units are always up to date. Disadvantages include RAID settings (motherboard function), which can be technically demanding. Raid 1 also doubles the burden on the computer processing unit (CPU) that could slow down some systems. In addition, the mirroring opens the door to damage both discs SSTEjná vocal event. Using the previous solution If the system operates after the program installation, for example, you canOut the "offline" clone unit to copy the primary unit and return it to the previous state.

If you do not tend to add a dedicated clone unit, the services of remote backup online are available. Users log in to subscribe to the service, set the login information to enter a secure server, and use the site software backup their system to a remote web server.

Advantages include easy use and access online to the computer backup system from anywhere in the world. Backup is also safe from damage that could affect your personal computer before a natural disaster or theft. Disadvantages include inherent risks of data placement on the server before you are not owned, and over which you have a small final control. It is also important to realize that you cannot introduce remote backup from online.
