Backups & RPO/RTO
For Backup types: full, incremental — RPO/RTO in one sentence each., interviewers listen for a crisp definition, how the pieces interact in a real system, and one trade-off or failure mode you have seen or would guard against.
| Type | Description |
|---|---|
| Full | Entire database snapshot |
| Incremental | Changes since last backup |
| RPO | Max acceptable data loss time |
| RTO | Max downtime to restore |
Test restore quarterly—untested backup is wishful thinking.
