Tape backup drives can be integral to the network or housed at remote locations. Tape backup provides a high amount of data storage at an economical price, but tape drive technology is becoming dated in computer fields. The largest disadvantage of a tape backup is the speed, which can be critical in situations where a restore is necessary. A DVD recorder can be used as a backup system that operates faster than a tape drive at a comparable price. The disadvantage here is the need to have personnel on location to change and label the disks.

Tapes and floppies are economical, but slow for server backups.
Disk Image Backups
A disk image is an exact duplicate of a hard drive compressed into a single large file. Disk backups can be stored on the server or on other media devices. Disk images can be created using common disk copying and burning software. The main disadvantage for using disk images is you cannot access specific folders or other data in the image; you must install the complete image to get to the data. Disk images are suited more towards laptop or home networks than large network applications.

A disk image makes an exact, compressed copy of the hard drive contents.
Cloned Drives
A cloned drive is an exact copy of one computer hard drive onto another hard drive. In the event of a drive failure, the two can be swapped out, returning the system to the last clone session. Cloning requires investing in dual drives and running frequent backup sequences. Automated cloning systems have the potential to transfer a computer virus or other malicious software, rendering the backup useless for a recovery. Scheduled cloning of server drives provides the ability to restore a drive to as little as minutes before a crash but must be monitored to prevent the introduction of undesirable code errors.

External hard drives are useful for disk cloning backups.
NAS Backups
Network attached storage (NAS) are essentially self-contained hard drives connected to the network. NAS systems may be the most dependable on-site backup for servers. They can be set up to operate using backups, clones or disk images. The least favorable aspect of a NAS is the price, which can be much higher than other types of server backup hardware.

A NAS box resemble as computer case, but lacks a motherboard and CPU.
RAID Systems
In a redundant array of independent disks (RAID) system, for every active drive within the server, a duplicate, identical drive exists. When data is written to one disk, it is simultaneously written to the other. RAID systems provide real-time backups that other server backup devices cannot match. For disadvantages, RAID systems are controlled at the motherboard or BIOS level and can be difficult to install. Because both disks receive the same data, older computers may face severe reduction in CPU performance. RAID systems do not have any defense against malicious code, and data written on the primary drive immediately corrupts the secondary drive as well.

RAID systems are usually installed in the server.

How to Set Up Filezilla for Joomla!In Feburary 2016 09,
In Feburary 2016 09,
Double-click on the FileZilla icon or select it from the start menu. FileZilla will start and display the local hard disk directory structure on the left side of the window.
Enter the domain name of your website or the IP address in the 'Host' field. Do not include the 'http://' part of the address, just the domain name. For example, 'mycoolsite.com' is a domain name and '192.168.2.1' is an Internet Protocol address. If your domain name hasn't been assigned yet, use the IP address provided by your hosting company.
Fill in the 'Username' field at the top of the screen with your FTP user name. Use the exact spelling and character case as the FTP user name issued by your hosting service provider.
Enter your FTP password in the 'Password' field at the top of the screen. Use the exact spelling and character case as the password issued by your hosting service provider.
Enter the FTP port number in the 'Port' field if your hosting provider uses a port other than 21. Most users will leave this field blank as 21 is the default port. Only enter a port number if your hosting provider uses a port other than 21.
Click on the 'Edit' menu, then click on 'Settings.' Select 'File Types' under 'Transfers' on the left side of the settings window. Click the 'Binary' radio button on the right side at the top of the window. This setting ensures that binary files such as archives and backup files transfer properly. If such files are accidentally treated as ASCII files, they may become corrupted during transfer. Having this set correctly is especially important for uploading Joomla! installation files, Joomla! extension packages and downloading backup files.
Click on the 'OK' button at the bottom of the settings window to save the settings. Click the 'Quick Connect' button to the right of the host, username, password and port fields previously entered. FileZilla will connect to your Joomla! website root directory on the server and display the file structure in the right side of the window.
Click on the 'File' menu, then click on 'Copy Current Connection to the Site Manager.' This saves your settings and allows you to select them the next time you use FileZilla from the Site Manager. Just click 'File' then 'Site Manager' or press 'Ctrl - S.'
