What are the options for implementing backup under given conditions?

Question

Backup

There are 6+ Win-terminal-servers on which 30+ 1C file bases live.
A bat nickname is launched on each server every day, which closes all 1C processes and backs up each database to its archive on NAS-1.

Thus, on NAS-1 we have a bunch of backup archives for a long time, decomposed into subfolders (by database names)

I want to implement a system that will store the last N instances of all databases on NAS-2, copying the new one from NAS-1 (and deleting obsolete).
Ideally, the same system will upload these last N-copies of each database to the cloud / s3.

I didn’t remember a ready-made suitable product offhand.
Writing a set of scripts for this business is essentially reinventing your own wheel.

Please tell me if there is something ready-made (free) that suits me?
(BareOS please do not offer - I came across in due time. I did not like it)

Shl. the solution is not necessarily for Windows. Perhaps for Linux it will be even more convenient.

What also prevents a batch file or a posh script from being thrown, which would pull out the last N backups or backups for the last N days and store them for K days? From the free one, take a look at Cobian backup.
