In the OP, given
1. Convert the snapshot dir's datetime name to epoch
2. In the trip script apply the epochs to a parabolic function: y = x^
is the epoch equivalent of the directorys' timestamp and y
is the value on which the decision to backup (or not) is made - as determined by applying the function to the epoch.
Is that of any help ?
A user level that continues to overstate my experience :-))
