That's one backup every hour for 7+ years. I'm really curious about the use case. Anyway, theoretically[0]: > As you might know btrfs treats subvolumes as filesystems and hence the number of snapshots is indeed limited: namely by the size of files. According to the btrfs wiki the maximum filesize that can be reached is 2^64 byte == 16 EiB But it seems practically you're hitting the mud at ~100 snapshots[1] but be sure to read the reply to that mail as it will depend on the use case and it might turn out to be fine way beyond that.
