- 1Image level• Bare metal backup using images • Operating system volume snapshots or hypervisor snapshots • Recover the entire system at once • Make an exact copy somewhere else
- 2File levelCopy individual files to a backup • May not necessarily store all system files • May need to rebuild the OS and then perform a file restore
- 3Critical applicationsApplication software • Often distributed across multiple servers • Application data • Databases, other data storage • Location of data • Local and cloud-based • All of these are needed when restoring • They all work together
- 4Backup testingIt’s not enough to perform the backup • You have to be able to restore • Disaster recovery testing • Simulate a disaster situation • Restore from backup • Confirm the restoration • Test the restored application and data • Perform periodic audits • Always have a good backup
- 5UPSUninterruptible Power Supply • Short-term backup power • Blackouts, brownouts, surges
- 6Surge protectorNot all power is “clean” • Self-inflicted power spikes and noise • Storms, power grid changes • Spikes are diverted to ground • Noise filters remove line noise • Decibel (Db) levels at a specified frequency • Higher Db is better
- 7Cloud storage vs. local storage backupsData is available anywhere, anytime, on any device • If you have a network, you have your data • Advantages over local backups • No tape drives to manage • No offsite storage processing • Disadvantages over local backups • Data is not under your direct control • Strong encryption mechanisms are critical
- 8• Account recovery optionsApps won’t work if users can’t login • Your Windows Domain will most likely be the foundation of your recovery efforts • Consider other authentication requirements • Multi-factor authentication validation
Additional authentication databases • RADIUS, TACACS • Another good reason for centralized administration • No local accounts - 9—
