Large number of snapshots on a ZFS system
Solution 1:
There's no problem with lots of snapshots. Having thousands of ZFS filesystems can cause boot times of more than an hour, but you're not doing that.
Solution 2:
I wouldn't be too concerned about this. You're talking about 1 snapshot a day here. I have heard of production environments with over 10k snapshots. But I don't have any information on how this was working for them but I didn't hear it in a bad context so I'm going to assume that it was working well.
