I want to do a daily replication to another Truenas system, at a different site, which will be used solely for backup (specifically, it will not have NFS/SMB turned on; it is solely as a backup).
1) What is the best way to configure snapshots for this? I am guessing I should have replication-specific snapshots, if only for performance reasons - I have many hundreds of datasets so many tens of thousands of snapshots, which makes replication go extremely slowly if I just point it at the 'auto' snapshots.
1a) In replication, what is the difference between 'recursive' and '(Almost) Full Filesystem Replication'? Why would you choose one over the other?
2) I am wondering about how deletion works. Suppose I have a daily snapshot, kept for two weeks, which get replicated to the backup server. Someday, my primary server is destroyed, and I have to switch to using the backup server. Is all the data on that server going to evaporate two weeks later?!
