My apologies for being unclear. I was referring to the new backup naming option available in v0.19.
Like you, I generally just use the numbered versions. That said, chrisb mentioned an issue I will have to look into more deeply. So I may be revising my earlier opinion. For now, with my limited number of backups, the number scheme seems to be working just fine.
The new option would be very useful if there was also an option to set a separate path to store backups. Then they could be stored elsewhere on a separate drive, network, or cloud, adding a possible additional physical layer of protection to the data
