3 questions regarding Backrest

Hi,

Recently after losing some important files, I started exploring file level backup software that would upload my important folders to cloud storage on a daily basis. Previously, I was only using image level backup software on a monthly basis.

Backrest + Restic sounds like a very atrractive FOSS option based on the amount of features they offer.

I had some questions though as I found some conflicting imformation during my search:

1. I have my backup set to run daily at 8 am as below. My question is, let's say my laptop was in sleep mode/shut down until 11 am, will the Backrest schduler automatically detect that it missed a backup schedule and start running a snapshot when laptop is awoken?

2. Let's say I'm running for the 1st time & taking a full file backup which takes about 6 hours. If the idle sleep timer on my Windows/macOS is set to 15 minutes, will Backrest keep the laptop awake post 15 minutes or does this have to be handled separately?

3. I have some confusion in regards to how retention policy works based on the options shown below.

I want to make 2 backup plans:

a) One that runs daily & should keep deleted/modified files for 30 days before it is removed from the cloud.
b) One that runs on a adhoc basis manually every 30-45 days and should keep only 1 deleted/modified version of the file. (So essentially at any given moment, it should have the latest file + the most recent deleted/modified files.)

How can I achieve the above 2?

Essentially, how does Backrest determine what is Daily, Hourly? Like if my cron is running daily it might go under daily but what if it's running every 3 days, every 3 weeks or 2 months? How does it determine daily, weekly etc. in that case?

Did some testing on this, both on Windows and macOS cuz I own both & plan to run Restic on them.

On Windows, it worked as excepted, I set it to run at 8 am and woke my laptop at 11 am, it triggered on wake up.
But on macOS, it completely missed the schedule and just showed the next day's schedule as waiting. ☹️
