Changelog

v0.0.2 — 2026-06-19

Fixed

• B2 backup failing with NotImplementedError after a TrueNAS update. The patch block's guard (if "get_restic_config" not in B2RcloneRemote.__dict__) could misfire and silently skip injecting the method — most likely when a TrueNAS version adds a stub that raises NotImplementedError, causing the dict check to return False. The guard is removed; the assignment is now unconditional. This is safe because the native-support kill switch already prevents patching when TrueNAS ships a real, working implementation.

• Native-support check falsely triggering kill switch on stubs. The check now inspects the source of any pre-existing get_restic_config before concluding that TrueNAS has shipped native B2 support. If the method body contains NotImplementedError it is treated as a stub and patching continues; only a method that does not raise NotImplementedError triggers the kill switch and auto-disable.

v0.0.1 — 2026-06-16

Initial public release. Extends TrueNAS SCALE's TrueCloud Backup feature to work with S3-compatible providers and native Backblaze B2 in addition to Storj, using volatile overlayfs patching of the TrueNAS middleware that persists across system updates via a PREINIT initshutdownscript.

Included

• install.sh — registers the PREINIT boot hook and applies patches immediately
• patch/apply.sh — PREINIT script; mounts writable overlays, patches b2.py and restic.py, patches the Angular UI bundle to widen the credential dropdown
• patch/create_task.py — CLI to create TrueCloud Backup tasks with S3 or B2 credentials, bypassing the Storj-only restriction in the UI
• recover.sh — emergency recovery; sets the kill switch and restarts middlewared
• uninstall.sh — full removal of the patch and PREINIT hook
• Kill switch support (disabled file) for safe degradation
• Auto-disable when TrueNAS ships native B2 restic support
• hook_status.json written on each boot for create_task.py verify
