Best Practices for Data Backup in Linux Operations

In daily operations, data backup is a crucial step. If data backup is not done properly, data loss due to accidental system crashes or other unexpected events can be irreversible.

It’s advisable to manually back up relevant files before making any configuration changes or updating code, as this allows for quick restoration in case of errors.

It’s also a good practice to regularly back up important data to quickly recover from data loss and avoid long business interruptions, which can pose a risk of data leakage.

After backing up data, it’s best to move the backup files to a secure location to prevent data loss. Secure locations can include another disk, cloud storage, or a dedicated backup server.

Maintaining a copy locally and keeping another copy in a separate physical location ensures redundancy and enhances disaster recovery capabilities.

Three common backup methods are introduced here.
