I clicked on the link. offer of $4.98 is first year only. then $95.
I am pretty impressed with iDrive so far. Backed up 450 GB in about three and a half hours. Basically went about as fast as my internet connection could handle. I like the interface and I restored a few files to check the backup. I did not time a full restore. It seems the introductory $4.98 for 10 TB deal is perpetual, but may be a bit hard to find. Oh, and there is no limit on the number of computers you are backing up. With the versioning (limited to 30 copies), you need to make sure that your cloud storage is at least 3 (my made-up number) times your local storage.
