I can see that being a very large gap if it is not easy to see if your files are actually backed up or not. That kind of surprises me a little bit that back blaze doesn't have that but again it's been many years since I've used them and I only did briefly.

That is one of the features that is very easy to see in spider oak. The UI opens to a dashboard that tells you the number of items and bytes that are outstanding and waiting to be uploaded. One other thing about spider oak is there's not an automatic retention like I believe you said 30 days you have to plug in the hard drives to keep them refreshed. In spider oak I've had systems that have been offline for years and the backup is still retained until I manually go delete that system to have its data purged. One of the other features I do like about them is their hive that allows you to synchronize between systems as well. So depending on your requirements you can back up things to their cloud for redundancy and maybe things that are of a lower priority you can simply have it synchronized between various systems.

The One singular feature that sold me on spider oak as opposed to every other provider I looked at was their Linux support. How they don't really treat Linux or even a Windows servers as different from any other thing you're backing up. You purchase your amount of cloud data and they don't care.

Just doing a little more looking at my spider oak and their UI I feel can be a little bit slow at times especially navigating large amounts of files but I did double check this and nothing gets automatically purged from their system based on time. Even files that are deleted from your local system simply go into their deleted items bucket and they are there in perpetuity until you manually go purge it to free up space.
