External hard drives are pretty cheap nowadays.

This ^^^

For the security of your sensitive data and credentials, I strongly suggest to backup everything locally. I trust a physical location (example external HDDs), than cloud storage. For example, look what happened with MegaUpload many years ago. I have 4 HDDs and perform daily Incremental backups (backs up only data changes on a day-by-day basis).

Some day 4 HDDs Is an overkill but In the event of failure, hard disks can be replaced, loss of data (In It's absolute entirety) cannot.

Cant afford one so local server from old desktop it is
