Borg backup is a good tool in my opinion and has everything that I need (deduplication, compression, mountable snapshot.
Hetzner Storage Box is nothing fancy but good enough for a backup and is sensibly cheaper for the alternatives (I pay about 10 eur/month for 5TB of storage)
Before that I was using s3cmd [3] to backup on a S3 bucket.
D'argh.
In other words, a backup can be degraded into a sync-to-nothing situation if the client logic is untrustworthy.
Just this weekend, my backup tool went rogue and exhausted quota on rsync.net (Some bad config by me on Borg.) Emailed them, they promptly added 100 GB storage for a day so that I could recover the situation. Plus, their product has been rock solid since a few years I've been using them.
Sorry to hear about your troubles. Hope your backup situation's sorted out?
Do you recall if you used a link like this to sign up?

If you don't, a good heuristic would be to see how much you pay per GB - if it's less than a cent, you probably did. The ones that come with support are typically a shade above per a cent per GB
Just to clarify - there are discounted plans that don't have free ZFS snapshots but you can still have them ... they just count towards your quota.
If your files don't change much - you don't have much "churn" - they might not take up any real space anyway.
It would be incredible if you started to look into S3 compatible object stores, unless you have made a business decision not to support it.
Thank You for providing an affordable option for self hosters.
There is 100% a difference between "dead data" (eg: movie.mp4) and "live data" (eg: a git directory with `chmod` attributes)- S3 and similar often don't preserve "attributes and metadata" without a special secondary pass, even though the `md5` might be the same.
