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. Rsync to make incremental backups of all user data Even some sensitive files that may be stored in a secure, fireproof safe with limited access to the trusted company personnel.Ī multiphase bare metal restore and data recovery plan using native CentOS tools may consist of −ĭd to make and restore production disk-images of configured servers #Os x shell script to create admin deploystudio full#Where Windows uses a micro-kernel architecture.Ī 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 RecoveryĪ 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.
