Why Does Windows 7 Backup Take So Long?

The reason for the backup being larger than the source, in my case anyway, is that by default Windows Backup makes a backup of “Files in libraries and personal folders for all users” and it also makes a complete system image — so my user data is being backed up twice.

How long does a backup take on Windows 7?

Hence, using the drive-to-drive method, a full backup of a computer with 100 gigabytes of data should take roughly between 1 1/2 to 2 hours.

Why is my Windows backup so slow?

Make sure you’ve got enough bandwidth to handle both the backups and any other traffic on the network at the same time. A failing network component or a bad connection will also slow the backup. These and other network problems will usually show up in the network logs.
