New page

This is a very basic guide on using [https://pve.proxmox.com/wiki/PVE-zsync pve-zsync] to send backups to a macos host with [https://openzfsonosx.org/ ZFS] running on it via ssh.

= configure repository =
Lets first make the zfs dataset that all this will live under. We want to prevent the host os from seeing the virtual devices under it 'volmode=none' does this.

zfs create -o volmode=none ZfsMediaPool/proxback

= Configure user on mac =

We want to use and unprivileged account on osx and setup it to allow ssh.

sysadminctl -addUser proxback -home /Volumes/ZfsMediaPool/proxback/
chown -R proxback:wheel /Volumes/ZfsMediaPool/proxback/

Now we need to make the .ssh files to allow the sending proxmox hosts to ssh in as proxback.

You will need to grant this user ssh access in System Preferences > Sharing > Remote Login for ssh to work.

= ZFS perms =

Allow this user to do anything under the proxback dataset

zfs allow -u proxback create,mount,receive,send ZfsMediaPool/proxback

= symlink the zfs binary =

mac installs the zfs binary in the path, but the pve-zsync uses absolute paths. It's fixable, but easier to just symlink it on osx

ln -s /usr/local/zfs/bin/zfs /usr/sbin/zfs

= configure ssh on proxmox =

I use a nonstandard port number so in the .ssh/config file I need to setup my server:

Host proxback
hostname IPADDRESS
port 2022
user proxback

= ssh to the server =

ssh to the server as root and test that you can login

ssh proxback

= Do the first backup =

time pve-zsync sync --compressed --source 116 --dest-user proxback --dest proxback:ZfsMediaPool/proxback --dest-config-path /Volumes/ZfsMediaPool/proxback/pve-sync --verbose --maxsnap 7 --name test flowman

== verify it made it on the server ==

# zfs list -r -t all ZfsMediaPool/proxback

NAME USED AVAIL REFER MOUNTPOINT
ZfsMediaPool/proxback 51.7G 78.2T 2.59M /Volumes/ZfsMediaPool/proxback
