Improve automated backups and config diffing in NCM tools

Hey all, Throwing this out there because we're in the middle of evaluating NCM/config backup tools and I'm going a little cross-eyed reading vendor docs. Would love to hear from people who've actually run these in production. We're mainly looking at Unimus and rConfig, with Oxidized loosely in the mix – though I suspect Oxidized might not cut it for us on the security/auditing side without a lot of extra work. A bit of context on our setup: we're an MSP with a few hundred devices today, probably pushing \~1000 before long. Mostly Cisco and Aruba. Small team (3-6 engineers), multi-client environment, and connectivity is sometimes a mess – VPNs, jump hosts, devices sitting inside client networks, the usual fun. Core things we need: solid automated backups, config diffing, and ideally the ability to push changes. Compliance and audit features would be a nice bonus. Basically trying to figure out: * Which of these actually holds up in production without babysitting * What the upgrade/maintenance experience is like over time * Whether support is responsive or you're on your own * How well they handle multi-tenant/MSP setups * Security and auditing depth If you've gone through a similar eval – or just have strong opinions from running any of these day-to-day – I'd genuinely love to know what you picked, why, and especially anything you wish someone had told you before you deployed it. Appreciate any real-world takes, even if it's just "X was a nightmare, avoid it."
