How has zfs replaced rsync for you? One is a filesystem, and the other is a filesyncing tool. Does zfs do something im not aware of lol?
I used to use
rsyncto copy data from my storage array on one machine to an external and an off site backup. Since a lot of it was code, it always took forever to scan all the small files, and I had to script unlocking remote partitions.With encrypted ZFS, I can just
zfs snapthenzfs send, and it does the same thing at the block level, raw, so way faster, less data transfer, and no need to send a key or passphrase unless I need to mount it at the destination (meaning a cloud provider could never know the data, for instance).ZFS is also recursive, so if I have
s/storageand/storage/stuffdefined, I can snap and send either level, which makes it as versatile as rsync.Oh interesting, i am not super familar with zfs' tools, so thats pretty cool! Ill have to look at that for my storage array.
