How to put Windows into data saving mode?

Question

Hard disks

I have 500 GB occupied on the disk, the same amount is free. The disk starts to crumble (they said in the repair).
How to instruct Windows 10 to start duplicating data in case of a breakdown?

UPD
But there is also folder synchronization. I just haven't figured out how to set it up yet.

SOLUTIONS
Following the advice in the comments (John Smith) and from the Internet, I did the following:
1) I broke the hard drive into two parts. Transferred data from C: to D:. Then again I bit off a piece from C:, but Windows 10 does not attach a piece to the drive located on the right.
The AOMEI Partition program helped.

2) I bought an external hard drive for 2TB (SDD expensive) Maxtor.
a) With the help of AOMEI Backupper, I made Disk Backup and threw it on an external drive (it was not useful in step 3)
b) On a 15GB flash drive (although 16GB was needed), I made a system recovery disk.
c) C room. Microsoft Synctoy did synchronization of data from drive D: to an external drive.

3) At work, we bought a GIGABYTE 1TB SSD in M2 format. The AOMEI Backupper program made a clone of the hard drive on an SSD in sector-by-sector copy mode.

I pulled out a bad hard drive - Windows worked on the SSD, did not even write about activations (I saw such problems in the descriptions of programs and on the Internet).
