Backup Solutions for Virtualized File Servers with Large Files | CompTIA Cloud+ Exam CV0-002

Best Backup Solution for Virtualized File Servers

Question

A company is seeking a new backup solution for its virtualized file servers that fits the following characteristics: -> The files stored on the servers are extremely large.

-> Existing files receive multiple small changes per day.

-> New files are only created once per month.

-> All backups are being sent to a cloud repository.

Which of the following would BEST minimize backup size?

The best option to minimize the backup size in this scenario is Differential backups.

Differential backups are incremental backups that only backup the data that has changed since the last full backup. This means that when a new backup is created, only the changes made to the files since the last full backup are backed up, rather than backing up the entire file.

In this scenario, since existing files receive multiple small changes per day, differential backups will only backup those small changes made to the files and not the entire file. This will minimize the backup size, reducing storage and bandwidth requirements.

Local snapshots, file-based replication, and change block tracking are other backup solutions, but they do not necessarily minimize the backup size in this scenario.

Local snapshots are copies of data taken at a specific point in time, and while they can reduce the recovery time, they do not necessarily minimize backup size.

File-based replication involves copying the entire file to another location, which would not minimize the backup size in this scenario, as the files are extremely large.

Change block tracking keeps track of the changes made to a virtual disk, but it does not necessarily minimize backup size in this scenario, as it would still need to backup the entire file each time a new file is created.
