You can use SRM or vSphere Replication in your VSAN infrastructure. You can replicate the virtual machines in your infrastructure to a different site. vSphere Replication is included in your current license. You also do not need to make a purchase.

Please, if this solution helped your problem, "Helpful" if it solves your problem "Correct Answer" to mark.
A couple of ideas for your DR.
- vSAN is as redundant as you want to configure it, of course, more disk groups with more disks will become in something more robust.
- Depending on the corruption for vSAN, the data could be useless, I mean, if your RAID5/6/whatever fails, all your data couldn't be re-constructed, therefore, no data.
- Best thing for redundancy is replication to another site/location, more disks per diskgroup, in order to increase resiliency and have a good VMware contract, is always a must!
Hope this helps.
It must have been highly stressful time for you and your team. It is sad to hear and a bit difficult for me to imagine.
Few important points
- You need data protection strategy (what if vSAN itself becomes corrupt?)
- You need Business Continuity Plans for (Thinking outside the box I realized we have no other storage array to move data to and that would have saved us in this event.)
- How redundant vSAN is (you have FTT option to decide) and above 1, 2 points.
If I were you I will divide this goal into three parts
1. Things which you can do immediately
2. Things which you can do in 6 months
3. Last, in one year.
1. Easy Wins
- Is your team properly trained on vSAN? Have they read vSAN operation guide
- Is your monitoring for vSAN component properly configured? If not, configure it
- Is your vSAN configured as per VMware recommendations, if not this is the time?
2. Short Term Fixes
- Do you how much your Services/Applications/Servers/VM are Mission Critical?
- Now attached the RTO and RPO requirement for it. If there are not in place, start majoring how early you restore your backup data
3. Long term Plan
- Remote site (Availability zone, Region) defined by VMware Validated Architecture
- The decision on vSAN Stretched cluster
- Classical Approach.
I hope it helps if you wish to discuss more please reach me out.With Great Regards,1 person found this helpful
