Problem
Backup repository encryption for a repository located in a CentOS 7 or newer machine does not work.
Background
NAKIVO Backup & Replication uses ecryptfs and cryptsetup to encrypt backup repository data. As of CentOS 7, ecryptfs is not automatically included in the operating system. As a result, you need to install this kernel manually.
Solution
CentOS 7
To configure the ecryptfs kernel in CentOS 7, first install ecryptfs-utils by running the following command.
yum install -y ecryptfs-utils
Then, install the kernel module for ecryptfs by running the following command (in this case, from ELRepo).
rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org yum install -y https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm yum install -y kmod-ecryptfs
CentOS 8
To install the ecryptfs kernel in CentOS 8, run the following command.
sudo yum install epel-release sudo yum install ecryptfs-utils
