I realise the question is confusing, so allow me to elaborate. I apologise for the phrasing, as I wasn't sure how to put it.

Here's the scenario: As my backup, currently my Mac launches Rsync every 12 hours to copy data from an external hard drive to another external hard drive. I like this backup method as a workaround to mirror the data in both sides without having to do RAID. I do not use the Rsync version that comes with the OS, but rather I got the latest one using the Homebrew tool for OS X.

The problem is I want to reinstall Yosemite from scratch, and these hard drives (there's more than one hard drive copying to another hard drive - I have various drives, each with their respective "clone" drive to have nice data redundancy) contain a lot of data and are encrypted with VeraCrypt, and the initial backup took a pretty long time for each. We are talking about 500 GB - 1TB drives.

So what will happen once I put the hard drives and their "mirrors" in the new setup? Will I have to start using Rsync from scratch or will Rsync know that I have used it with another setup before and continue the "mirroring" from there, considering that the hard drives will be exactly the same ones as before?

Rsync doesn't keep any memory from one run to the next. If you move a file to a different computer, rsync doesn't care.

If you interrupt rsync in the middle of transferring a large file (it isn't clear from your question whether you intended to do that), that file is lost. To keep partial transfers, pass the --partial option.
