Quick Reference Table
| # | Scenario | Key Error Signal | Root Cause | The Fix |
|---|---|---|---|---|
| 1 | EBS Snapshot limit exceeded (Incomplete/Pending stuck) | ConcurrentSnapshotLimitExceeded | Trying to create multiple concurrent snapshots exceeds the limit of one pending snapshot for st1/sc1 volumes, or five for other volume types. | N/A |
| 2 | Multi-Volume Snapshot Set Failure | "event": "createSnapshots", "result": "failed", "cause": "Snapshot snap-01234567 is in status error" | If any one snapshot in a multi-volume snapshot set fails, all other snapshots are moved to an error status and the creation fails. | N/A |
| 3 | Incomplete Backup Due to OS/Application Caching | "This might exclude any data that has been cached by any applications or the operating system." | File writes are not paused and the volume is not unmounted before the snapshot command is issued, leaving cached data out of the point-in-time snapshot. | N/A |
| 4 | Encrypted Snapshot Copy Fails Silently | "StateMessage": "Given key ID is not accessible" | Attempting to copy an encrypted snapshot fails silently if the user lacks DescribeKey permissions on the default CMK or the snapshot's customer master key. | N/A |
