	How many backups to retain:		How many backups to retain:

			These settings used to be called "hourly, daily, weekly, monthly" in older releases of rsnapshot, but were changed to "alpha, beta, gamma, delta" because the time interval between backups is arbitrary.

			Setting this means I end up with 6 backups which were done most recently, then one of those gets hived off to become the beta backup, which it keeps 7 of, one of which gets hived off as gamma, and so on. This means you have multiple alpha backups fairly recently, multiple older beta backups representing days then gamma representing weeks and delta backups going back months. Set this according to how many backups you want to have.

	retain ~~daily~~ 7		retain alpha 6
