I believe it was selected because the licensing options and costs were much better than Veeam’s offering.
To be honest I can’t comment much further - it was set up by a colleague, it runs in a different country, and I’ve never needed to do a restore from it because I’ve always been able to recover lost files/emails from the recycle bin/recoverable items.
It’s more of an insurance policy against ransomware or other malware than anything else. It’s good to have, but not used day to day.
Although that does remind me that we are probably due a test restore. I’ll add that to the list for this month. Thanks! 😉
