Right now, I have around 20TB of data in redundant ZFS mirrors, so I am somewhat protected against any single drive failing. Critical data is backed up at various cloud providers, but that’s only a few gigs of all my data.
Looking at S3 pricing, It seems rather unfeasible to back up my data there or on the other “big” cloud providers, as it would cost me around $180 with AWS or half of that with backblaze.
How and where do you guys back up your data?
The amount of data I backup offsite is significantly less than 20 TB. Therefore, my answer to your question will probably not help you.
I store my offsite backups at rsync.net and in one of Hetzners Storage Boxes. For backups in general, I use Borg.
Hetzner Storage Boxes seem much more affordable than AWS, thanks for the suggestion!
However, I would not use the storage boxes as the only backup. The offer has two disadvantages.
The boxes are regularly unavailable for some time due to maintenance work. But these maintenance times are announced in advance.
Hetzner does not specify what kind of RAID is used.
I therefore only use my box as an additional offsite backup and to swap out less important files.
