We can back up data stored on one of your local drives and we can also back up data stored on another computer in the workgroup, such as a share that we have mapped as a drive. However, placing the backup on someone else’s computer doesn’t necessarily mean that the backup is safe from accidental erasure or corruption.
Having a backup copy of the computer data allows restoring the data if the data is accidentally deleted or if there is any hardware problems such as a failed hard drive. For example, if the hard drive fails, put a new hard drive in the computer, install Windows and other software, and then restore the backed-up data files to the new hard drive. All that has lost is the time it takes to put in a new hard drive and restore the files. Important data that has been backed up can also be restored to an entirely different computer, which is particularly useful if we are upgrading to a new computer.
All software development and web development company India backing up the data on the network, use two alternatives: local backups or backups over the Wi-Fi network. Because a workgroup network is a grouping of peer computers that share resources among the individual computers, local backups allow each computer user to select and back up the files she feels are important. Backing up locally to a backup device directly connected to a computer is a fairly fast process and does not consume network bandwidth; backing up over the network can actually slow down the network.
The other alternative is to have a device on the network dedicated to the backup process such as a computer designated as a file server or a network backup drive that is directly connected to the Wi-Fi network. However, to back up to another computer on the network, tie up processing power on that computer during the backup. And because the data must travel on the network, the backup will take more time than backing up to a directly connected local device.
For example, a directly connected USB hard drive can provide a transfer rate of 480Mbps while the Wi-Fi network can transfer data at only a maximum speed of 56Mbps (unless we are using some type of speed-boosting technology on the router and adapters, which can provide faster throughput but still not as fast as a directly connected drive). So, directly connected backup devices are always going to be faster and more reliable.
