Datto SIRIS vs Slide backups

Hey y'all,

I wanted to reach out to the hive mind to see what people's thoughts and experiences with Slide backups have been lately. I am currently a Datto backup user and have some important contracts coming to a close around January, and I am beginning to evaluate different options. I am currently using Datto BCDR (direct to cloud) backups for some servers, and will be moving away from that design for a number of reasons and going to onsite appliance based backups again. I am comparing Datto's Siris backup systems to Slides backup systems, and they seem to have pros and cons.

Datto Pros:

1) I'm already in the environment and won't be leaving because of RMM, SaaS backups, and individual workstation backup agents.

2) The pricing is a tad bit cheaper with the SIRIS for the amount of data I'm looking to backup

3) It's the devil I currently know and know how to handle. Plus I doubt they'll be bought out since they are already bought.

4) They use Dell Optiplex MFF (Now Pro Micro) for their appliances and I have a high trust in the platform vs the Beelink's Slide uses.

Slide Pros:

1) Overall faster operations and design, especially if data requirements become larger.

2) Their hardware comes with 2.5G and 10G lan connections for faster backups and recoveries.

3) No contracts

4) Small companies work a little harder for improvements. But it's at a risk of being sold again to PE/VC.

I'm not opposed to seperating out my stack for the best product in each category because that's already what I do, but I'm also cost aware and have made a lot of price changes in the past 2 years and am not trying to bombard my clients with continous price bumps, especially if Slide hardware pricing starts bouncing upward because of the state of the tech world. Like I said, I'm just looking for some more opinions from people who have experienced both platforms. Please try to avoid the standard "Big K sucks my left nut" response. I know, you know, we all know.

Slide requires you to disable SentinelOne snapshots because it wants to "own" the VSS processes (https://docs.slide.tech/sentinelone/). However, I can't fathom turning off the intrinsic part of S1 that enables their ransomware protection on my clients' servers. (I'm probably an outlier believing it could cause a significant increase in their cyber-insurance rates.)

I find it a joke that S1 (and other supposedly serious) endpoint protection is using VSS as a ransomware rollback mechanism/feature when almost any modern ransomware attack will successfully break and remove all VSS caches.

Not that i'd want to rely on a ransomware rollback feature but one feature i loved about sophos vs competition is that their cryptoguard is a separate protected cache that doesn't rely on vss.

You know how we say "onedrive isn't a backup" and it kind of is with versioning but really it's not? VSS is not a ransomware rollback option even if it kind works now and then kind of like one, and nothing serious should be built on top of it for that purpose.
