Did my boss say I should look into ways of doing a backup, so far I know how to restore the OS,
but would like to know how to recover ALL data,
What else is there for methods, I still know the copying of the hard drive on an external storage by device, but do not know how to do that if the hard drive is damaged.
That's why I wanted to ask questions, I thank you in advance for any answer
Data recovery is only known to me with external tools.
Or playing back with already secured things on a network.
But in order not to let the loss of data occur at all, there are many different possibilities. RAID, grandfather principle, windows backup, backups to a network, etc.
Windows has built-in functions for it
But would like to know how to recover ALL data,
All data can be restored, if one has created an image (hard disk image) of all partitions.
The internal Windows backup creates such an image, but IT usually uses external programs for it.
The image copies all the data of a partition at the bit level.
This article describes the Windows internal version of image creation and a variant with an external tool:

Data basically on a separate drive and then… Backup backup backup! Best a NAS with mirrored plates (Raid 1). Food n 'a few Hunnis. I have at home. In addition, I make a backup once a month on an external hard drive, which I keep elsewhere.
Alternative: cloud backup. People take care of backup etc.
After the hard drive has gone I became a bit paranoid.
A NAS is still this device, where one packs the original hard disk in the "source (A)" and the external one on the other (B)
NAS: network attached storage, is a storage station in the LAN. Mine is in the basement and all PCs, tablets and smartphones in the household can access it.
How data security is organized varies:
Raid is data redundancy (Redundant Array of Independent Disks)
Raid 0: just a hard drive with network connection - well, roughly. Generally, two or more hard disks are made data technically one. Two 3 GB patten will make a 6 GB disk.
Raid 1: two disks (or systems) that are mirrored, that is, contain the same information twice. If one goes bad, the info is still on the other. You need twice as much storage capacity. So two plates or two Raid 1 systems.
Raid 5: A method where there's more than one hard disk for the data to be available. With four plates for data, there's a fifth. The data is stored in such a way that the data can still be restored if one disk fails. This is worthwhile only with large systems.
I have a Raid 1 with 2 x 3 GB.
A raid system is NOT a backup! Backup is storage completely elsewhere.
