Backup and recovery are critical tasks in system administration to protect data from loss, corruption, or disasters. Admins implement strategies to back up files, databases, and entire systems locally or remotely. Popular tools include rsync, tar, and Timeshift on Linux; Windows Backup and Veeam for Windows. Backups can be full, incremental, or differential based on needs and frequency. A strong recovery plan ensures minimal downtime and quick restoration in case of failure.
