Well, I have small funny story to share. I have folder `Notes` with ... well, notes (copy #1). - Inside it git repository (interesting thing, it was accidental, then I thought 'Why not?') which synchronizes with my git server (+1 copy) - It have repository file hystory (Let's exclude it for simplicity) - This folder syncs with my file cloud server (+1) - Servers uses ceph storage, so there is x3 copies of same data (x3) - Also, there are snapshots (Let's say x4) - In addition to that, there is offsite backups (Let's say x2) - File cloud syncs with another devices (Let's say x2) So in total I have `1x2+(1+1)x3+(1+1)x4+(1+1)x2 = 20` copies of same `Notes` folder! (if we count snapshots as copies)
