A support service that watches the mailbox can then identify the app, read the technical context, and draft a reply in the user's own language automatically. Nothing changes in how you reach support: you still tap **Contact Support** and type your message; the technical block is added at the bottom of the email for you. Implemented in `AppConstants.supportMetaBlock()` / `supportMailtoURL()` (no `UIKit` dependency — `ProcessInfo` + `utsname`), values mirror `DiagnosticLog.envSnapshot()`. | ### 2.3.0 — 2026-08-01 |---------|-------|------------|---------|-------------| | 2.3.0 | 44 | 2026-07-22 | Feature | **Back up when the iPhone is nearly full.** The Photos engine no longer copies each asset to a temporary file before writing it out — it streams the asset from the Photos daemon straight to the destination, hashing as it goes, so the device holds **one 4 MB chunk at a time instead of the whole file**. A 4 GB video used to need 4 GB free on the iPhone just to be backed up to an external SSD; it now needs almost nothing. Applies to every local destination (SSD, iCloud Drive) and to SSD + NAS together, where the SMB upload reads from the copy just written to the external volume rather than staging on the device. A NAS-*only* backup still stages, because AMSMB2 offers no incremental upload. **iCloud Drive destinations now free their local space as they go**: once iCloud confirms a file is uploaded, its local copy is released and only a placeholder remains — the file stays in iCloud and visible in the Files app. Waiting on uploads only happens when the device drops below 2 GB free, so a phone with room to spare backs up at full speed, and stalled uploads (no network, iCloud storage full) never slow the run down more than once. **New disk-space check** before a backup starts: it refuses only when nothing at all could be copied, so one oversized video no longer blocks the two hundred small files behind it — that file is reported individually and the rest are copied. Also fixed: a failed export left its partial file behind, so a run that was already short on space made itself worse with every retry. Drone and SD card backups are unchanged. Also fixed a deduplication edge case on the Photos path: after an SSD was disconnected mid-backup and reconnected on a later run, files already uploaded to a NAS were re-uploaded, because the existence check compared the NAS copy against Photos' *estimated* size rather than the real one — the NAS is now re-checked against the true size and skipped if already present. **Destination independence when one drive fails mid-backup:** unplugging an SSD (or a full iCloud Drive folder) no longer stops the other local destinations — each is dropped on its own, at both handle-setup and mid-write, and the rest keep going. **Correct multi-destination report:** a file copied only to a reconnected drive is no longer wrongly shown as "Copied" on the iCloud/NAS destinations that already held it — the summary now separates "copied this session" from "already present" per destination, and a destination that never received a file reads as Failed rather than silently appearing complete. | ### 2.2.1 — 2026-07-12 | Version | Build | Date | Type | Description | |---------|-------|------------|---------|-------------| | 2.2.1 | 41 | 2026-07-11 | Improvement | **Richer diagnostic logging (crash/jetsam tracing).** `DiagnosticLog` now records device environment on every key event to make one-shot crash reports self-sufficient. `[LAUNCH]` and `[MEMORY_WARNING]`/`[THERMAL]` carry an `envSnapshot()`: used/total RAM (`phys_footprint` — what iOS jetsam watches), free disk, thermal state, low-power mode, **phone language** (`lang=`) and **in-app language override** (`applang=`, `auto` = follows system) so support can reply in the user's language. A positive cold-start chain now proves a healthy launch: `[LAUNCH]` → `[STORE_OK]` (SwiftData store opened) → `[UI_READY]` (first frame, written once from `ContentView.onAppear`) → `[STARTUP_OK]` (onAppear finished, UI interactive, with store/destinations/sources/premium summary). Where the chain stops pinpoints the failure stage. New lifecycle breadcrumbs via `DiagnosticLog.installObservers()`: `[LIFECYCLE]` (background/foreground/terminate), `[THERMAL]`, `[POWER]` (low-power toggled), `[DATA_PROTECTION]` (device locked/unlocked). `[PROGRESS]`, `[BACKUP_START]` and `[BACKUP_END]` now include a compact `mem=used/total` tag, so a rising memory footprint approaching total RAM on constrained devices (e.g. iPhone XR / `iPhone11,8`, 3 GB) reveals a jetsam memory-kill. Logging only — no behavioural change. ### 2.2.0 — 2026-07-06 | Version | Build | Date | Type | Description | |---------|-------|------------|---------|-------------| | 2.2.0 | 40 | 2026-07-06 | Feature | **NAS (SMB) backup destination.** Back up directly to a NAS over Wi-Fi via a native SMB2/3 client (AMSMB2/libsmb2) — on the LAN or **remotely** (e.g. via Tailscale/VPN, incl. cellular). Configure host/share/folder/credentials in Settings → Destinations → **NAS (SMB)** (Pro; password in Keychain) with a **Test connection** button; the NAS appears as a destination in the Dashboard with live capacity. Works alongside or instead of local SSDs (**NAS-only** supported). Files are uploaded **directly** (no local staging) and verified by full **SHA-256 re-download**. **Browse** tab: navigate the NAS folder-by-folder with on-demand download + QuickLook preview. **Mobile-data awareness**: a warning banner appears when backing up to the NAS over cellular, plus a **Stop** button to cancel any running backup (session marked Partial). Onboarding gains a NAS network diagram + feature bullet. Architecture: engines refactored onto a `BackupTarget` abstraction (`LocalFileTarget` / `SMBTarget`). Removed the DEBUG SMB Probe and the 3rd "SD Card (transit)" destination slot. Also fixed a dedup edge case — a corrupted/wrong-size file at a known path is now re-copied (coverage check verifies size, not just existence). **LUT Grade on NAS destinations (parity with local SSD):** the NAS Browse view now offers the full LUT Grade feature — assign a `.cube` LUT per NAS device folder, preview videos with the LUT applied in real time (full-screen player instead of QuickLook), and **multi-select** which videos to grade (a folder often mixes LOG and non-LOG footage, so grading is per-video, never "grade all"). Grading downloads each selected clip from the NAS → grades locally → uploads the HEVC result to a `Device (Graded)` folder on the NAS; already-graded files are skipped. Also fixed a LUT bug affecting both local and NAS: a failed export no longer leaves a partial file that was wrongly treated as "already graded". | ### 2.1.6 — 2026-06-24 | Version | Build | Date | Type | Description | |---------|-------|------------|---------|-------------| | 2.1.6 | 38 | 2026-06-23 | Improvement | Support email address changed to `photovideobackup@icloud.com` (was `supportphotovideobackup@gmail.com`); updated in app (Settings/Diagnostic mailto) and documentation. | ## More apps by Gerard DUVAL - [ND Easy](https://appshunter.io/ios/app/nd-easy/id6783327572) All apps by Gerard DUVAL: https://appshunter.io/developer/1890192604 ## Related topics [portable ssd](https://appshunter.io/ios/topics/portable-ssd) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
