Dear Forum,

I'm still having troubles to get that right: How do I set up Backup Rotation right?
I hope you can clarify this for me.

What I want: Daily backup, only keep one version per month during the last 12 month, older versions only 4 per year (every 3 month).
My settings:

The preview window shows me one backup-version after 4 weeks, one after 8 weeks, … thats fine.

But what I get is one version per day, so it takes a huge amount of target-disk-space…
Why are the intermediate versions not deleted?

Thank you for any hints.

Synology support gave the answer:

Please note in general: When the set amount of versions won't be reached, so the rotation also won't be activated or run in backround to delete older versions. Please double check this. This is a very common for many cases.

We recommend to set up the intelligent rotation named "smart recylce". Please read also below hyper backup rotation options:

With best regards

So rotation rules only apply if you are exceeding "the max number of versions". This approach doesn't make a lot of sense to me. It will take much more backup space than actually needed until you reach the max number…

That's what I did now - it's just a little hassle to calculate the right number of versions to be sure to keep the oldest one… :/
