With R1soft you can create backups at bit level. To use R1soft you have to install an agent which is available on Linux and Windows. For each Operating System there are different instructions:
CentOS, Red Hat and Fedora
wget https://gist.githubusercontent.com/MrKoopie/4b636d7a2ebab70634e96e949ab77d02/raw/c1e447eebee8eaa8995269887d95f0d0d2641559/install_r1soft_rhel.sh -O - | bash
Debian and Ubuntu
echo "deb http://repo.r1soft.com/apt stable main" >> /etc/apt/sources.list wget http://repo.r1soft.com/r1soft.asc apt-key add r1soft.asc apt-get update apt-get install serverbackup-enterprise-agent serverbackup-setup —get-module serverbackup-setup —get-key https://backupxxx.ispnoc.net
Replace backupxxx with the name of the backupserver.
You can find the detailed installations instructions of R1soft on Windows: at the website of R1soft.
Are you using a firewall (if you do not, check here how to install a firewall)? Remember to open the incoming tcp port 1167 for the backupserver. You can find the backup server IP by using the command
host backupserverxxx.ispnoc.net. Replace 18.104.22.168 with the server’s IP and execute the command when you have CSF installed.
csf -a 'tcp|in|d=1167|s=22.214.171.124'
