Greptile Summary

This PR makes a single documentation update to README.md, improving the Backups feature description to mention volume backups and listing specific storage destinations. The addition of "and volumes" is accurate — volume backup support exists in the codebase. However, the listed destinations "(S3, SFTP, FTP, Google Drive)" are partially inaccurate: the entire backup system is built exclusively on rclone's S3 driver, and there is no SFTP, FTP, or Google Drive implementation anywhere in the project.

• ✅ "databases and volumes" — correctly reflects the existing volume-backup feature
• ❌ "SFTP, FTP, Google Drive" — these destination types are not implemented; all backup utilities only support S3-compatible storage

Confidence Score: 2/5

Not safe to merge as-is — the README advertises backup destinations (SFTP, FTP, Google Drive) that are not implemented in the codebase.

The only changed line introduces a factual inaccuracy in the public-facing documentation, claiming support for storage backends (SFTP, FTP, Google Drive) that do not exist in the codebase. This could mislead users evaluating or setting up the tool.

README.md line 23 — the storage destination list must be corrected to only reflect S3-compatible providers.

Inaccurate storage destination list

The updated description claims backups support "S3, SFTP, FTP, Google Drive" as destinations, but a review of the codebase shows that only S3-compatible providers are implemented. All backup utilities (postgres.ts, mysql.ts, mongo.ts, mariadb.ts, libsql.ts, volume-backups/backup.ts, etc.) exclusively use getS3Credentials and the rclone :s3: backend. The handle-destinations.tsx form only exposes S3 fields (accessKeyId, secretAccessKey, bucket, region, endpoint), and constants.ts lists only S3-compatible providers (AWS, GCS, Cloudflare R2, Minio, etc.).

There is no SFTP, FTP, or Google Drive code anywhere in the project. Advertising unsupported destinations will mislead users who rely on the README to evaluate the tool.

Consider correcting the line to reflect what is actually implemented:

Suggested change

	- **Backups**: Automate backups for databases and volumes to external storage destinations (S3, SFTP, FTP, Google Drive).
	- **Backups**: Automate backups for databases and volumes to S3-compatible external storage destinations (AWS S3, Cloudflare R2, Minio, GCS, and more).
