Generations of Backup / Individual Retention Management Rules

Hi all,

currently I am testing Acronis True Image 2014 for my personal backup. This includes documents and a lot of photos. (Doing photography semi-professional at the moment... well, lot of data... )
However, I ran into a conceptual issues or at least, I cannot find the right solution for my desired backup plan.

The desired backup schedule itself is quite easy, but retention management (cleanup of backups) is the hard part here. I want:
- Daily incremental backups
- Each week a full backup shall be created and the incrementals can be thrown away (or kept to allow a 'delete after 7 versions' rule)

- Keep only one full backup per week within the current month (all other weekly fulls from older months can be removed)
- Keep only one full backup per month within the current year (all other monthly backups from older years can be removed)
- Keep all yearly full backups

Now, at first I tried to achieve this with one backup rule. No chance at all, as I cannot define anything relating to current month, current week, or whatsoever.

Then, I tried to create several backup schedules covering my needs. Two downsides:
- Waste of storage capacity, whenever the yearly full is stored in parallel to the monthly full and the the weekly full (not each time, but you get the idea)
- There is no 'yearly' schedule. The least often schedule says 'once per month'

Did anybody of the other users run into such or likely issues? Could you think of ideas to work around the limitations?

If somebody questions why I want to do this, my reasoning is:
- Daily backup to cover the normal progress and unintended deletions
- If I discover any date in future, a virus killed some photos (or made them nonsense), I want to be able to go back in time ... even in years ...
- For being more storage efficient, I thought, keeping it granular for the current year/month/week is enough, as long as I keep the next higher level (at least a backup of each year must be kept)

Thank you in advance. This question really keeps me thinking a lot.
