What are the options for protecting against accidental / intentional / hardware data loss?

Question

Backup

Something budgetary, without special requirements for the speed of information transfer. But more convenient than copying by hand.

Ideally, everything (well, except for any system files) that is created on the main HDD falls into the backup HDD, but is not deleted, even if it was deleted on the main HDD.

At the same time, everything that fell on the backup HDD could be viewed (and approved for saving (or deleting)) separately from the files that were saved during the previous, so to speak, approval for saving. In short, a kind of wastebasket in which one could poke around a lot.

But the bottom line for the most part is that if the main HDD crashes, or a virus is atrocious, or something else, there are copies of the data on the backup HDD.

Answer 1

Look at https://www.duplicati.com/ , it can save to disk\NAS

Answer 2

You can use almost any software for backup. The main point is that the backup should not be located in the same place as the data being backed up, and also that there should not be _easy_ access to the backup from the main computer. Look in the direction of backup to the cloud (for example, backblaze and the like)
upd:
Free Veeam Agent can backup to the OneDrive cloud (if there is a subscription, then this is the best option)

Answer 3

Regular backup.
Use any backup software that is convenient for you.
I mostly use a simple script, shadow copies, zpaq for packaging, and console utilities to move to ftp, or cloud services.
