Here are some free options:
Cartel already mentioned - Seagate DiskWizard/Maxblast - you must have at least 1 Seagate/Maxtor drive. You can make backup images of drives/ partitions manually. There is no scheduling. There is no file/folder backup. I found it large and heavy on resources - but hey, it's free.
Macrium Reflect Free Edition. Images Drives / partitions - allows scheduling , mounting and restoring individual files from the mounted image. There is no separate separate file/folder backup with the Free Editon. Extremely small, fast relatively light - I have found it totally reliable.
Paragon do free Drive Backup Express version on their website - does a good job and is reliable - but very limited features.
Paragon also do a free promo. version , which is much better - it images drives/ partitions, and files and folders, and includes scheduling. Not as fulll featured as their paid versions - fantastic for a free product.
It is called Paragon Drive Backup 9.0 Personal SE. You might find it if you look around.
For individual file / folder backup ( not drives/partitions), GFI is well liked, as Barman58 pointed out.
Hope it helps
