@girish no, they're pretty useless. Their web UI S3 console is such crap it can't handle the chatty API requests and keeps timing out. Also I may be wrong that multiple directories are because of failures and restarts. It just looks like multiple changed apps per day get a new dir.
So I am attempting other workarounds. Like creating a new bucket and just nuking the old one.
rsync isn't great for object store backups as it makes a ton of small files.
tgz isn't great as it's a lot of repeated information.
We need something hybrid that is the best of both.
Something like backing up to a local Minio much more quickly then doing an object to object store transfer offsite, which is much more efficient. This may also offer an opportunity to dedupe and further optimize.
