The beauty of rsync is it works incrementally at the block level on a file-by-file basis. The following sync sent nearly 2.3GB of data across our LAN. Rsync is named for its purpose: Remote Sync and is both powerful and flexible in use.ДЇollowing is a basic rsync remote backup over ssh в€’

Explore and talk about some common options.

In this tutorial, we will discuss rsync in various ways в€’ In the author's opinion, one of the best features of sync is its ability to be scripted from the command line. rsync has been used for years by System Administrators, hence it is very refined for the purpose of backing up data. Rsync is a great utility for syncing directories of files either locally or to another server.

Restore data to the working server from backups If a system crashes due to a hardware failure or disaster, following will be the different phases of restoring operations в€’Д«uild a working server with a configured bare metal image

Also, this ensures someone else will know vital security credentials if the current administrator wins the lottery and disappears to a sunny island somewhere. Commonly, this can be put on a USB drive, encrypted and locked in a safe that a Senior Manager access. Tar & gzip to store encrypted backups of files with passwords and notes from administrators.

Where Windows uses a micro-kernel architecture.ДЄ full data restore and bare metal recovery are usually accomplished through a combination of methods including working, configured production disk-images of key operational servers, redundant backups of user data abiding by the 3-2-1 rule. The monolithic kernel used in Linux actually makes bare metal restores using system images much easier than Windows. Assuming 100% systems failure and loss of all past system hardware, an administrator must have a plan to achieve uptime with intact user-data costing minimal downtime. System RecoveryДЄ bare metal restore plan is simply a plan laid out by a CentOS administrator to get vital systems online with all data intact. Another modern approach may be a cloud backup provider. 1 copy of data offsite we are rotating the USB drives offsite on a nightly basis. We would actually have three different backup mediums in this case: the working copy on an SSD of a laptop or workstation, the CentOS server data on a RADI6 Array, and the offsite backups put on USB drives. 3-2-1 is defined as follows: 3 copies of data for example, we may have the working copy a copy put onto the CentOS server designed for redundancy using rsync and rotated, offsite USB backups are made from data on the backup server. This is a very good approach to live by when implementing a backup plan. Throughout the industry, you'll often hear the term 3-2-1 backup model. The first thing we want to get accustomed to is the 3-2-1 backup rule. Before exploring methods particular to CentOS for deploying a standard backup plan, let's first discuss typical considerations for a standard level backup policy.
