Deduplication Techniques to Minimize Backup Time
Question
The data backup window has expanded into the morning hours and has begun to affect production users.
The main bottleneck in the process is the time it takes to replicate the backups to separate severs at the offsite data center.
Which of the following uses of deduplication could be implemented to reduce the backup window?

A. B. C. D.B.
The use of deduplication can help to reduce the amount of data that needs to be backed up, which in turn can reduce the backup window. Deduplication is a process that identifies and eliminates duplicate data within a data set, resulting in a smaller amount of data that needs to be backed up.
In this scenario, the main bottleneck in the backup process is the time it takes to replicate the backups to separate servers at the offsite data center. Therefore, the implementation of deduplication should be targeted at reducing the amount of data that needs to be replicated to the offsite data center.
Option A: Implement deduplication at the network level between the two locations. This option involves implementing deduplication technology at the network level to reduce the amount of data that needs to be transmitted between the two locations. However, this may not be effective in reducing the backup window since the bottleneck is in the replication process rather than the network.
Option B: Implement deduplication on the storage array to reduce the amount of drive space needed. This option involves implementing deduplication technology on the storage array to reduce the amount of data that needs to be backed up. This can help to reduce the backup window, but it may not address the bottleneck in the replication process.
Option C: Implement deduplication on the server storage to reduce the data backed up. This option involves implementing deduplication technology on the server storage to reduce the amount of data that needs to be backed up. This can help to reduce the backup window, but it may not address the bottleneck in the replication process.
Option D: Implement deduplication on both the local and remote servers. This option involves implementing deduplication technology on both the local and remote servers to reduce the amount of data that needs to be backed up and replicated. This can help to reduce the backup window and address the bottleneck in the replication process.
In conclusion, option D - Implement deduplication on both the local and remote servers, would be the best solution to reduce the backup window while addressing the bottleneck in the replication process.
