I don’t do backups of a lot. The important stuff that has like, an actual backup, has 2 copies off site. One at my work, one at my wife’s work. Just a regular LTO tape. The vast majority of what I store, is not something I consider important enough to backup as it’s stuff like, dvds and blurays I’ve ripped and still have and thus could get out of storage and rip again should that need arise. I do however donoff site replication. 3 replica ceph pool where one copy has to be off site. There’s again one node at my work and one at my wife’s work, plus ofc the local cluster which for drive constraints in the work nodes, always has two of the replicas. Might add a second node at my work but while we both get to place the servers there, I still pay for power, and wife for power and connection. With power prices these days, it gets kind of expensive.
