Discuss the advantages and disadvantages of performing backups from a device installed on the server and over the network.
What will be an ideal response?
Performing backups from a backup device installed on the server has two important advantages:
No extra load is produced on the network from traffic caused by transferring files over the network.
Equipping each server with its own backup capability gives you a way to perform backups on a multiple-server network, even if a backup device fails on one of the servers. Backups can be performed from backup media on one of the other servers.
The advantages of performing a network backup are that backup jobs can be stored on a single backup media and one administrator can be responsible for backing up multiple servers. The main disadvantage is the increase in network traffic.
