v1.0.0 — AWS Integration for Frappe

Release Notes

v1.0.0 — AWS Integration for Frappe

Release Date: February 24, 2026

This is the first stable release of AWS Integration, a comprehensive Frappe app that brings Amazon S3 file storage, S3-based site backups, and SES email sending to your Frappe/ERPNext instance.

---

🚀 Highlights

• Unified AWS Settings — A single DocType to configure S3 storage, S3 backups, and SES email with a clean tabbed interface
• Zero-downtime migration — Migrate existing files and backups to S3 without any downtime; files remain accessible throughout
• S3-compatible providers — Not locked into AWS; works with Backblaze B2, Wasabi, MinIO, DigitalOcean Spaces, and any S3-compatible service

---

✨ New Features

S3 File Storage

• Instant & scheduled uploads — Choose between immediate background upload on file attachment or hourly batch processing
• Presigned URL serving — Files are served via time-limited presigned URLs with Frappe's native permission model enforced for private files
• Bulk migration — One-click "Migrate All Files to S3" with real-time progress bar showing upload count and failures
• S3 status dashboard — View files on S3, pending uploads, exempt files, storage sizes, migration progress, and recent errors at a glance
• DocType exemptions — Configure a list of DocTypes whose attachments should remain local (e.g., Print Formats, temporary files)
• Per-file actions — "Upload to S3" button on local files; "Delete Local File" button on S3-uploaded files (with confirmation dialog)
• Local file cleanup — Bulk clean up local copies of S3 uploaded files to free disk space, with path traversal protection
• Dedup compatibility — Frappe's content-hash deduplication works seamlessly; duplicated File docs are automatically marked as S3-stored
• File DocType override — Custom S3File class bypasses Frappe's disk-based validation for S3 API URLs
• Custom fields on File — s3_key, is_on_s3, s3_uploaded_at, local_deleted fields created automatically via after_migrate
• Collision-safe naming — Content-hash prefix added to S3 keys when different files with the same name exist
• Multipart upload — Files >5 MB use S3 multipart upload for reliability
• S3-compatible endpoint — Custom endpoint URL support for non-AWS providers

S3 Site Backups

• On-demand backups — "Take Backup Now" button with live status pipeline (Queued → Generating → Uploading → Done)
• Scheduled backups — Automatic Daily, Weekly, or Monthly backups via Frappe scheduler events
• Full site backup — Database dump, site config, public files archive, and private files archive
• Separate backup bucket — Optionally store backups in a different bucket from file storage
• Backup log tracking — S3 Backup Log DocType tracks every backup with status, timestamps, file sizes, S3 keys, and error details
• Retention management — Auto-delete old backups by count ("keep last N") and/or by age ("delete older than N days")
• Upload local backups — Scan the local backup directory and upload previously generated backups to S3
• Presigned download URLs — Download any backup file (DB, config, files, private) from S3 via time-limited URLs
• Email notifications — Configure notifications for backup success and/or failure
• Auto-retry — Failed backups retry up to 2 times before final failure
• Local cleanup — Automatic or manual deletion of local backup files after successful upload
• Configurable timeout — Adjustable background job timeout for large sites (default: 6000 seconds / 100 minutes)

SES Email

• SES v2 API integration — Send transactional emails via Amazon SES with HTML and plain text support
• Email queue override — Automatically replaces Frappe's default email queue flusher when AWS is enabled
• Batch email sending — Configurable batch size with built-in rate limiting
• SES logging — All sent emails tracked in AWS SES Logs with message ID, recipients (To/CC/BCC), subject, and status
• Automatic handler toggle — Enabling/disabling AWS toggles the Scheduled Job Type for email queue flushing

---

🏗️ Architecture & Security

• Row-level database locking — SELECT ... FOR UPDATE prevents race conditions between instant and scheduled upload workers
• Commit-before-delete pattern — S3 metadata is committed to the database before local file deletion, preventing data loss on commit failure
• Path traversal protection — All local file operations validate resolved paths against expected base directories
• Permission enforcement — Private file access requires authentication and document-level read permission
• Graceful disable warning — Disabling S3 when files exist on S3 shows a warning with file count (does not block save)
• Safe backup paths — Backup file operations validate paths are within the site's backup directory

🐛 Known Limitations

• No streaming — Large file downloads redirect to S3 presigned URLs rather than streaming through Frappe
• Single region — All S3 operations use the configured region; cross-region replication is not managed by the app
• SES sandbox — New AWS accounts are in SES sandbox mode and can only send to verified email addresses
