I am using ZFS(ZoL) over LUKS on home and on remote server. All is working perfectly and fast. I do snapshots by cron, but now I want to replicate them to some backup storage. I have a small 2-HDD dlink dns-323 nas, on which I have debian installed. My requirement is to have backups encrypted. I am not sure I can install ZFS and Luks into NAS. My question may be very stupid, I know it sounds crazy, but I have only one idea in this scenario. Create LUKS and ZPOOL on NAS, but unlock and run it remotely by LAN on a workstation. By NFS or NBD. How that sounds? If my lan connection is stable and ok, will it run fine? I thought about rsync, zfs send/gpg, but I need an ability to remove some snapshots on backup box and want it to be managed automatically, and keep synced with master. Any ideas?
