Backup rotation

Feature request: Date based backup folder and option to keep only x number of previous backups.

As a work around for date based backup folder, having the date variable in config works. an option to purge older than n backups will be a good addition.

[Backup To]
# E:\Backups      (example path)
D:\Personal Backup\$CurrentDate

a side affect of above is a '$CurrentDate' folder gets created in along size the date wise folders.
