Create the user/group hb (329 is the UID/GID of "oracle-xe" removed from SBo)

# groupadd -g 329 hb

# useradd -u 329 -g 329 -s /sbin/nologin -M hb

Download hb from https://www.hashbackup.com/hashbackup/download.html to /usr/local/sbin/hb
- # chown root:hb /usr/local/sbin/hb
- # chmod 750 /usr/local/sbin/hb
- # setcap cap_dac_read_search=+ep /usr/local/sbin/hb
# mkdir /var/hashbackup
- # chown hb:hb /var/hashbackup
- # chmod 700 /var/hashbackup
$ sudo -u hb /usr/local/sbin/hb init -c /var/hashbackup
Create /var/hashbackup/dest.conf
