2 days agoIt is a pain to figure out how to give everyone the same user id. I only have a couple computers at home. I’ve never figured out how to make LDAP work (including laptops which might not have network access when I’m on the road). Worse some systems start with userid 1000, some 1001. NFS is a real mess - but I use it because I haven’t found anything better for unix.
ZFS even if only one server is much better than most people have. If your ZFS replication is to a different building you have done pretty good. However as others have pointed out there are limits. Those servers costs you a couple bucks/month in electric (where I live my electric is 100% wind, but most of you should read CO2). You have to buy both servers, and hard drives will crash regularly.
There are a lot of trade offs, but cold storage backups are often much cheaper in the long run than the backup zfs server. And those cold backups are a lot easier to put into multiple different locations.
