Do you use a VPS/cloud hosting and if yes, may I ask which provider?
I have always used EliteHost and am very happy with them.
But I must prefaces I fully accept anything hosted by anyone will not be 100% private and secure.
Some are just better than others.
My main "interest" has always been data back up security.
I did experiment with a double blind cloud service recommendation from Michael Bazzell podcast, worth a listen if you are in OSINT and privacy, but can't remember the name of the service, I gave up own it due to the cost.
you pay a hang of a lot more for privacy and security.
I now have a pretty waxed system, the bulk is my important documents so not massive amounts of data in terms of volume.
I have a local network name with an encrypted back copy that auto runs.
I do a weekly back up to google drive of an encrypted archive folder. - the reason I choose to do it on google drive is they have the muscle and resources to keep there cloud secure and actively protect it, plus its cheap. In the same breath I do a secure archive folder because they do scan and have access if required.
I then do a monthly cold storage unencrypted back ie an external drive hidden "under the bed"
What is of interest to me but I have done the deep dive on yet is I believe Synology now allows you to sync two Nas over the net, I think that could be quite cool for a remote back up and then mange via adding the CloudFlare tunnels docker application on to the remote unit.
or using the CloudFlare Tunnels to do the sync.
