Greptile Summary

This PR makes a single-line change to README.md, updating the Backups feature bullet to add specific storage destination examples. Despite the PR description claiming a broad "reorganization," the actual diff is limited to one line.

The change introduces factually inaccurate information: SFTP, FTP, and Google Drive are listed as supported destinations, but the codebase exclusively uses S3-compatible storage (confirmed by the destination schema and the S3_PROVIDERS constants listing AWS S3, Cloudflare R2, GCS, DigitalOcean Spaces, Minio, etc.). Google Drive is also distinct from Google Cloud Storage (GCS), which is the S3-compatible option that is actually supported.

• The README description should be corrected to reference S3-compatible storage only, matching what the product actually supports.

Confidence Score: 2/5

Not safe to merge as-is — introduces a P1 documentation inaccuracy that misrepresents the product's capabilities to users.

The only change in the PR adds three unsupported storage destinations (SFTP, FTP, Google Drive) to the feature description. This is directly contradicted by the codebase, which contains only S3-compatible destination support. Publishing inaccurate feature claims in the README would mislead users and lower credibility.

README.md line 22 — the Backups bullet point must be corrected before merging.

Inaccurate storage destinations listed

The added destinations SFTP, FTP, and Google Drive are not supported by the codebase. Looking at apps/dokploy/components/dashboard/settings/destination/constants.ts, the only destinations exposed in the UI are S3-compatible providers (AWS S3, Cloudflare R2, Google Cloud Storage, DigitalOcean Spaces, Minio, etc.). The destination schema (packages/server/src/db/schema/destination.ts) uses S3 API fields exclusively (accessKey, secretAccessKey, bucket, region, endpoint), with no SFTP, FTP, or Google Drive support.

Note also that Google Drive is different from Google Cloud Storage (GCS) — GCS is listed as an S3-compatible provider, but Google Drive is a distinct service and is not supported.

The description should remain S3-focused, for example:

Suggested change

	- **Databases**: Create and manage databases with support for MySQL, PostgreSQL, MongoDB, MariaDB, libsql, and Redis.
	- **Backups**: Automate backups for databases to external S3-compatible storage destinations (AWS S3, Cloudflare R2, Google Cloud Storage, DigitalOcean Spaces, and more).
