how VR keep instance per day

[baber]

Dear All

Hi

my RPO is 15min

i have a question about point in time instance

i understand this from point in time  (instance that when i set keep 3 instance per day for the last 7 days )

it can just save 3 snapshot every day is that means if i start first synch on 07:00 the next sync is on 07:15 and finally is on 07:30 ?

or

1-do it  synch continuesly every 15 min from 07:00 untill 00:00 finally just keep 3 last snapshots ?

2 - is that mean when do 4th synch this snapshot will replaced with first snapshot ?

Here are a couple of examples:

- If you are retaining 24 in a 1 day period, it will have 24 “slots” for retention in that day.  It will keep the most up to date instance for each 1 hour slot.  If you have a 15 minute RPO you will have 96 slots, but it will keep only 24 of them.  So it will retain the most up to date replica *roughly* every 4 replicas.

- If you have say a retention of 6 in a 1 day period, then you have 4 “slots” per day.  It will retain the most up to date replica every 6 hours.  If you have a 15 minute RPO it will retain roughly every 24th replica.

The oldest snapshot will be discarded to retain the newest and stay under the 24 snapshot limit.
