Has anyone tried OwnBackup? Would you recommend it?

Although we have not used it but my research on this tool has lead me to conclude that it's been an excellent tool for automatically  backing up the data and metadata without compromising on the security aspects. It is compliant to many data privacy regulations and can be used to send alerts for suspicious actions by users such as bulk data deletion  etc.. 
However, it is bit costly and many alternatives are available at the modest price. If price is not the concern then it can listed on the top to be considered . 

I had a conversation with OwnBackup to understand their capabilities and value prop but did not explore anything beyond that. That was minor interest from my organization to use the backup and recovery option, but primary use cases would have been for data arching to maintain compliance. 

like others heard of it but we don’t use it but it looks like an interesting option

I haven’t used but have heard about it and seen some features which looks to be exciting but post thorough evaluation it can be looked at.

No. I will check and evaluate.
