Hello,
How to configure backuppc Schedule for this:
1-day - full
2-day - empty
3-day - empty
4-day - incremental
5-day - empty
6-day - empty
7-day - incremental
.....
14-day (or 15-day) - clear 1 day full and create new full
Need ONE full on 2 week and time to time
incremental
I resetup
FullPeriod - 13.97
FullKeepCnt - 1
FullKeepCntMin - 1
IncrPeriod - 2.97
IncrKeepCnt - 12
But I see backupams:

(sorry FullPeriod - change from 7)
But why one FULL and two incremental then full, why not full ->
10x incremental...
I'm not sure why the fulls are different time periods (9 days then
16 days) unless you have been messing with the FullPeriod between
runs or something caused the last full to fail for a couple of days
before it succeeded.
You will not be able to keep only one full the way you are doing
it. Incrementals depend on the previous full, so full backups will
be kept until the incrementals that rely on them are removed.
However, due to the pooling of duplicate files, keeping extra fulls
will not result in using much extra storage, so it shouldn't be a
problem.
To be more specific, you are keeping 36 days worth of incrementals,
so you need about 36 days worth of full backups to support them. In
practice, this means that BPC will need to keep 3-4 fulls to support
the incrementals depending on the exact timing.
