Add a client to tykbackup
The following steps should be followed to add a new client to TykBackup:
Add SSH key
Make sure the folder /root/.ssh
exists, and add the public ssh key below to /root/.ssh/authorized_keys
to allow the backup server to log in as root using ssh:
from="backup.tyknet.dk,10.100.100.18" ssh-rsa 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 root@backup.tyknet.dk
Configure sshd
Also change PermitRootLogin no
to yes in /etc/ssh/sshd_config
, the (sensible) default in FreeBSD is to not allow root logins over ssh.
Consider disallowing password logins and use key login only, and always firewall ssh.
Configure firewall
Allow SSH logins from backup.tyknet.dk
or 10.100.100.18
to allow the backup server to login.
Install rsync
Dirvish uses rsync, so install the port /usr/ports/net/rsync/
with the default options:
sudo portmaster /usr/ports/net/rsync/
Install sysinfo
I use Daniel Gerzos sysinfo port to get some information about the server included in the backup. It is called from the backup server before the backup starts, so it must be installed on the client:
sudo portmaster /usr/ports/sysutils/sysinfo/
I normally check both options, dmidecode and portaudit, to get as much info as possible.
Change root shell to sh
Dirvish runs the pre-* and post-* hooks with sh, so the root shell needs to be sh instead of the default csh:
sudo chsh -s sh
This shouldn't matter much, since you shouldn't be using the root account for actual work anyway.
