Two years ago my server SSD suddenly died on me during a routine restart, it was then I realized my users backup routine had failed several months prior and I had to rebuild everything as best I could using emails, public web achieves, and several other methods that took days. Now I have a local backup server that pulls hourly/daily/monthly DA backups of the system and users, and it emails me if there is any issues. Very comforting, but there's still been a lack of complete peace in my mind because I would still need to reinstall the server, installed utilities, and DA itself. To that end, I've spent some time looking into creating a weekly server image that could be installed, then I'd just have to update/overwrite the DA users from the image with their most recent daily user backup.
I was looking into Rsync for this when I came upon the Relax-and-Recover (ReaR) utility. Looks like it does exactly what I was hoping to do:

I did some searching to see if any DA admins had any previous feedback/experience using ReaR, but nothing came up. Just hoping to know if there are any tips, gotchas or drawbacks to this using this utility on a DA server. Would I be able to install the ReaR image and back up and running without any (DA) issues? If something wasn't the exact same, say the DA license/install updated since the image was created so the license/install didn't match what DA had on file, would I face an issue where DA wouldn't function until I got the issue rectified?
