Golden rule for sys admins- 1

 Backup everything and make sure to regularly validate those backups.

Backing up your data is absolutely crucial in case anything goes wrong. It's like having a safety net to fall back on if something unexpected happens. So, make it a habit to back up all your important files, configurations, and databases regularly.

Why it matters:

1. Protects against data loss: Hardware failure, ransomware, or human error won’t destroy your data.

2. Ensures business continuity: Quick recovery keeps operations running smoothly.

3. Reduces risk: Validating backups ensures they are complete and usable.

4. Complies with regulations: Many industries require reliable backup procedures.

Best Practices:

• Back up all critical data and system configurations, not just files.

• Store backups offsite or in the cloud in addition to local copies.

• Schedule regular automated backups to reduce human error.

• Test restores regularly to confirm backups are reliable.

• Keep a backup retention policy to manage storage and versioning.
