Retention points vs. retention days

[RubinCompServ]

With the upcoming release of v13.1, we're starting to prepare for our upgrade from v12. One of the changes that has our customers concerned is the forced move from retention points to retention days. Often times, they'll configure one-off (or manual-run) backup jobs because they need/want to keep a VM at a certain point in time (compliance, audit, dev/test, etc) and they're concerned that they'll lose some required points unless they configure a crazy-long retention time, which then sticks them with unnecessary points. Another concern is that if a job is configured for 14 days of retention and fails for 2 days (e.g. over a weekend), they're going to lose the 2 oldest points, which drops them below the 14 restore points that they want to actually keep. Finally, they're concerned that retention for their weekly/monthly/yearly backup jobs will become less clear as, instead of saying "Run yearly and keep 7 points", they're going to have to say "Run yearly and keep 2562 days", which isn't nearly as clear.

Does anyone else's customers have any of these concerns? If so, how did/do you address them?
