Repository Fuctionality

Setup:
If I create repository and put daily snapshot in it then on the 31st day start deleting the oldest snap and continue to do this day after day without end. Each day create a new snapshot and delete the oldest one.
The documentation says even if a snapshot is deleted that data is not deleted if it is needed by subsequent snapshots.

Questions:
Does this mean that the repository will always contain what is necessary to do a full restore?
Does it also mean that the repository will just continue to grow in size regardless of how many of the daily snapshaots are deleted from it provided the most current one is
always retained?

Say after a year of using the first repository in above scenario a second repository is created when the first snapshot is put into it will that snapshot be a complete snapshot or incremental ?

Is there a way to delete a repository?

Yes. All needed segments referenced by a snapshot will remain.

If some segments are not referenced anymore by any snapshots they will be removed.

If you create a new repository it will create a full backup again.
