It’s the method of guarding against and detecting illegal access to your computer system. Data security refers to the process of securing data from illegal access or any disaster. This process includes the following terms: Data backup Data Recovery What is the meaning of backup and restore? Backup and restore refers to technologies and practices for making periodic copies of data and applications to a separate, secondary device and then using those copies to recover the data and applications  Difference between Backup and Recovery 1. Backup: Backup refers to storing a copy of original data which can be used in case of data loss. Backup is considered one of the approaches to data protection. Important data of the organization needs to be kept in backup efficiently for protecting valuable data. Backup can be achieved by storing a copy of the original data separately or in a database on storage devices. The cost of backup is affordable. The prior goal of backup is just to keep one extra copy to refer in case of original data loss.  Difference between Backup and Recovery 2. Recovery refers to Restoring lost data by following some processes. Even if the data was backed up still lost so it can be recovered by using/implementing some recovery techniques. The cost of recovery is expensive. The prior goal of recovery is retrieve original data in case of original data failure. Importance of Backup and Restore  The purpose of the backup is to create a copy of data that can be recovered in the event of a primary data failure.  Backup copies allow data to be restored from an earlier point in time to help the business recover from an unplanned event.  NTFS-FAT32 Windows supports three different file systems namely FAT32, ex FAT, and NTFS. FAT32 or the file system is one of the File Allocation Table oldest file systems available on the Windows machine. It was first introduced on MS-DOS 7.1 / Windows 95 OSR2 in 1996 replacing the previous FAT16 file system.  NTFS First introduced in 1993, it is used in newer versions of operating systems such as Windows NT and 2000 and later versions of Windows. The New Technology File System or NTFS was developed for Windows NT, and it was a default file system for all the members of the Windows NT family of operating systems right up until Windows XP which kind of combined NT and the framework of the traditional windows together. On Windows XP , the NTFS became the default for Windows including Windows 10 which you may well be using today. Power-UPS UPS: Uninterruptible Power Supplies can offer protection to your equipment and essential services throughout your infrastructure. A standby UPS resorts to battery backup power in the event of common power problems such as a blackout, voltage sag, or voltage surge.  When incoming utility power drops below or surges above safe voltage levels, the UPS switches to DC battery power and then inverts it to AC power to run connected equipment. Activity 3  What are the backup devices?  Compare between NFTS and FAT32.
