How to Automate Backups with rsync and cron on RHEL 7 Reliable backups are the foundation of any serious system administration strategy. On RHEL 7, rsync combined with cron provides a powerful, scriptable, and highly efficient backup solution that requires no commercial software or complex infrastructure. rsync transfers only changed file blocks over the network, […]
Introduction FreeBSD 15 is a UNIX-derived operating system renowned for its network stack performance, ZFS integration, and Jail isolation primitives. Setting up mount cifs windows shares on FreeBSD 15 follows the rc.conf/service(8) paradigm rather than systemd, which means enabling a service and configuring its startup options are done differently from any Linux distribution. This guide […]
How to Set Up Software RAID with mdadm on RHEL 7 Software RAID (Redundant Array of Independent Disks) allows you to combine multiple physical disks into a single logical device that provides redundancy, improved performance, or both — without requiring a dedicated hardware RAID controller. On RHEL 7, the mdadm utility is the standard tool […]
Introduction How to Configure GEOM RAID on FreeBSD 15 is a core administration task for any FreeBSD 15 server operator. FreeBSD 15 ships with the 15.0-RELEASE kernel, ZFS as the default root filesystem, Capsicum capability sandboxing improvements, and an updated ports tree. Unlike Linux distributions, FreeBSD uses rc(8) for service management, pf for packet filtering, […]
How to Configure Samba File Sharing on RHEL 7 Samba is the go-to solution for integrating Linux servers into environments where Windows clients need to access shared files and printers. It implements the SMB/CIFS protocol natively on Linux, allowing RHEL 7 servers to appear as ordinary Windows file shares on the network. Whether you are […]

How to Set Up NFS File Sharing on RHEL 7 Network File System (NFS) is a distributed file system protocol that allows a server to share directories over a network, enabling client machines to mount and access those directories as if they were local storage. NFS has been a cornerstone of Unix and Linux networking […]
Introduction This guide explains how to Configure UFS Soft Updates on FreeBSD 15 on FreeBSD 15. FreeBSD uses the pkg(8) binary package manager, rc.conf(5) for service startup configuration, and pf(4) as its primary packet filter. There is no SELinux or AppArmor — instead, FreeBSD provides the MAC (Mandatory Access Control) framework and Capsicum for fine-grained […]
How to Configure LVM on RHEL 7 Logical Volume Manager (LVM) is one of the most powerful storage management tools available on Linux. Unlike traditional partitioning, LVM introduces an abstraction layer between physical storage devices and the file systems that use them, enabling administrators to resize volumes online, create snapshots for consistent backups, and pool […]
Introduction How to Set Up ZFS Snapshots and Replication on FreeBSD 15 is a core administration task for any FreeBSD 15 server operator. FreeBSD 15 ships with the 15.0-RELEASE kernel, ZFS as the default root filesystem, Capsicum capability sandboxing improvements, and an updated ports tree.
