What is Data backup? What is its type? Explain each in brief?
Answers
Answer:
Effectively backing up your files, networks, servers, and other assets begins with addressing the capabilities of a network and selecting the proper type of backup for the circumstances. The different types of backups available to managed service providers and IT administrators include:
Full backups – A full backup is the most basic of all backup types. And as its name suggests, it’s also the most comprehensive. In a full data or system backup, all data is copied to another location.
Advantage: A complete copy of all data is available in one location and restoration time is minimal.
Disadvantage: A full backup takes longer to execute than other types of backups.
Incremental backups – This type only backs up the information that has changed since the last backup occurred.
Advantage: Because only the changed data is being backed up, an incremental backup can be carried out as often as needed. Incremental backups are completed quickly and require fewer resources.
Disadvantage: While incremental backups have the fastest backup time, they also boast the slowest data recovery time.
Differential backups: Similar to an incremental backup, a differential backup copies all data changed since the last full backup every time it is run.
Advantage: A differential backup provides a way of backing up changed data to the same convenient location as all new data.
Disadvantage: A differential backup requires more time and space to complete.
