which of the following is the backup software
Answers
Answer:
Backup software are computer programs used to perform a backup; they create supplementary exact copies of files, databases or entire computers. These programs may later use the supplementary copies to restore the original contents in the event of data loss.[1] Hence they're very useful to users.
Answer:
Backup software is a form of system maintenance software. The backup utility is software that automatically schedules your computer to make backups. This is usually done while the computer is not in use.
A backup is a copy of your computer system that you can use to recover your computer’s files from in the event of a system failure. There are different types of backups that can be done:
A complete backup will make a copy of an entire computer system and allow you to recover from it. This takes a relatively large amount of time if your computer uses lots of storage space. However it is easy to recover from since all the files are in one place.
Another form of backup is called an incremental backup. This will only copy the files that have changed since the last backup. However the first backup must be a complete backup, and complete backups will be done periodically to stop the backup from being too messy, this also makes sure everything is included. This takes less time as not as much needs to be copied at a time, however is more complicated to recover from. This is because there are multiple copies of the same file, but with slight changes.
Both backups are used regularly, especially by large corporations that need to make sure their data is not lost. For certain organisations, a data loss would be fatal to their company.
Backups can either be stored onto a local drive, or onto the cloud. The cloud is normally used for smaller files, like photos on a person’s phone. Local storage would be needed if you were making a backup of lots of data, as it would take too long to transfer all the data to the cloud.
Backups can be done for lots of files, on lots of different devices. Google Photos automatically backs up your photos from your phone onto your Google Drive, so that you can access them later, without using the storage on your phone, or if your phone breaks.
