Online backup software. help

I am working on backing up my computers, the one part I would like some help on is the online part.

Also i am looking to get the best i can for free, and probably only backing up the most inportan stuff.

Out of my reaserch Mega seems to be a good idea, and mabye ADrive, both give 50GB free.

I also came accross Tencent Weiyun, though I don't know how much I trust a company offering 1TB of data from china.

Also I think i will encrypt everything before i upload it.

What do you think of what I have here, and do you have any sugestions.

thanks.

If you would like to have a second backup plan, to go with your online backup plan:  two external usb 1TB-3TB HDs, Macrium Reflect [free or fee].  At least twice monthly, make OS and data partition full-images onto each ext HD, to compliment your well-thought-out online plan 

Ok sorry 

  make OS and data partition full-images onto each ext HD.

Sorry but I am a little confused by what you mean by "Full-images." Would copying the recovery image ot an HDD also help.

Pretend you have the following partitions on one hard-drive: Manufacturer's recovery; System Reserved, OS, data; OS being C, data being D; recovery & SysRes should not have drive letters normally.  Yes, you can make a full backup of each partition, you only need Manuf & SysRes once, your data D can be monthly or bi-monthly, your OS C can be a full image monthly or bi-monthly.
