# RepositoryVerificationException: [my_repo] verification failed: could not write to repository at path [s3://bucket/backup]

- **ID:** `elasticsearch/repository-verification-failed-write`
- **Domain:** elasticsearch
- **Category:** config_error
- **Verification:** ai_generated
- **Fix Rate:** 88%

## Root Cause

Elasticsearch cannot write to the configured snapshot repository path due to permissions or connectivity issues.

## Version Compatibility

| Version | Status | Introduced | Deprecated |
|---------|--------|------------|------------|

| 8.10.0 | active | — | — |
| 8.14.0 | active | — | — |

## Workarounds

1. **Verify the S3 bucket permissions and ensure the IAM role has `s3:PutObject` access: `aws s3api put-bucket-policy --bucket backup --policy file://policy.json`.** (90% success)
   ```
   Verify the S3 bucket permissions and ensure the IAM role has `s3:PutObject` access: `aws s3api put-bucket-policy --bucket backup --policy file://policy.json`.
   ```
2. **Test the repository path manually using `curl -XPUT 'localhost:9200/_snapshot/my_repo' -H 'Content-Type: application/json' -d '{"type": "s3", "settings": {"bucket": "backup", "region": "us-east-1"}}'` and check for errors.** (88% success)
   ```
   Test the repository path manually using `curl -XPUT 'localhost:9200/_snapshot/my_repo' -H 'Content-Type: application/json' -d '{"type": "s3", "settings": {"bucket": "backup", "region": "us-east-1"}}'` and check for errors.
   ```
3. **Update the repository path to a writable location, e.g., change `s3://bucket/backup` to `s3://bucket/backups/` and ensure the path exists.** (85% success)
   ```
   Update the repository path to a writable location, e.g., change `s3://bucket/backup` to `s3://bucket/backups/` and ensure the path exists.
   ```

## Dead Ends

- **** — The underlying write issue remains unchanged. (90% fail)
- **** — A timeout increase does not fix permission or connectivity errors. (85% fail)
- **** — The new repository may have similar issues if the path is incorrect. (75% fail)
