Hi,
Thanks to your advice, I started to get a little more acquainted with Cloudberry.
Finally, in your advice, I don't understand.
(backup Full versions of files)
I understand that the version of the file is based on Date.
Where do the options "-everyfull, -atfull" save when I save all versions of a file? For example, I save three versions based on the date (maximum number of saved versions: 3) and bac up again using the "full" option. After that, I think it is right to have 6 versions, but I can not see it when I test it.

If you have a link to an academic article on the "full" option, would you share it?

Hi , thanks for your comment.
I thought a full backup from "Cloudberry" would keep backing up the same files every time.
As I understand it, I finally understood that "CloudBerry" does not support full backup.
The full backup I'm talking about here refers to a full backup of the following sites.

But I still have questions.
For example, what are the options like "-everyfull, -atfull"?

@Gleb Thanks for your comment.

What I understood from the thread you gave me was that I understood that a full backup would only be done on the first backup and then incrementally backup.
But I still have questions.
