My question - is this limitation on total number of snapshots on the system or only on related (parent<->child) chain of snapshots? What I want to do is the following: create (and then rotate) last 7 daily snapshots (and maybe 4 weekly) for each user in his /home dir. For around 100 users. So if limitation is only on related snapshots then I'm OK since only each 7 (or maybe 7+4) of them are related which is well under the 15-20 limit. However in total there could be 700 snapshots. So what is true? Thank you!
