rsync with mode --delete

[Budi Janto]

Hallo,

I need to know, I use rsync-3.1.3_1 under FreeBSD both of server &
client side. Server running ZFS with RAID system, stored data mount
point to /mnt/DATA. Under certain circumstances, ZFS failure to mounting
data in /mnt/DATA (Just empty directory), so client with rsync running
periodically with mode --delete it's safety or will remove data on
client too?
