Detailed explanation-1: -Speed. The backup speed is one of the most important factors you should consider for your data backup. When you first add an appliance to a system, the first complete backup usually takes some time. But after the first backup is complete, the subsequent updates should take less time.

Detailed explanation-2: -Click Start, type backup in the Start Search box, and then click Backup and Restore in the Programs list. Click Back up files under Back up files or your entire computer. Select where you want to store the file backup, and then click Next.

Detailed explanation-3: -Prioritise Security. The last thing to consider is security, but it’s probably one of the most important. You can’t back up all your data and leave it in a random location. Poorly secured backups leave not only a few documents open to hackers but tons of data.
