# Changelog
|
||
|
||
All notable changes to NG Backup are documented here. The format follows
|
||
[Keep a Changelog](https://keepachangelog.com/en/1.1.0/); versioning follows the stages in
|
||
`PLAN.md` section 9. The `<version>` in `appinfo/info.xml` is plain SemVer-numeric (Nextcloud's
|
||
own `info.xsd` doesn't allow a `-alpha`/`-beta`/`-rc` suffix there); the stability stage is instead
|
||
carried by the git tag, the release, and this file.
|
||
|
||
## [0.1.0-alpha.1] - 2026-10-05
|
||
|
||
First public alpha. Feature-complete for phase 1: scheduled, encrypted, incremental backups, and
|
||
restore of files and folders. **Not for production use** — test on a copy of production (dev,
|
||
test, staging). Full disaster recovery (`backup:restore:full` on a fresh installation) is phase 2
|
||
and not implemented yet.
|
||
|
||
### Added
|
||
- Encrypted (XChaCha20-Poly1305), content-addressed, deduplicated, incremental backups, streamed
|
||
from source to destination without a local copy of the data.
|
||
- Backup locations via files_external's own backend/auth classes, without ever mounting the
|
||
location: S3 (and compatible services), SFTP, WebDAV, FTP, Swift, or a local path.
|
||
- A recovery kit with up to three passphrase slots, mandatory download-and-confirm before the
|
||
first backup runs, and an optional encrypted copy by email.
|
||
- Resumable, time-boxed background jobs (database dump, file walk, upload), so a run survives
|
||
short PHP time limits and a crash is resumed, never restarted, without leaving the instance in
|
||
maintenance mode.
|
||
- Database dump and restore without external tools, via Nextcloud's own `IDBConnection`/DBAL,
|
||
streamed through the same pipeline as file data.
|
||
- Restore of files and folders via the web interface and `occ`, into a new folder, merged, or
|
||
replacing the original (with the previous content going to the trash).
|
||
- Retention policy (last/daily/weekly/monthly), prune with pack repacking, and a snapshot trash
|
||
with a configurable deletion delay.
|
||
- Append-only locations and documented recommendations against ransomware and a compromised
|
||
server (object lock, delete-less credentials, off-site copies).
|
||
- Admin settings page (locations, schedule, retention, key management) and a JSON API.
|
||
- Notifications and an admin setup check for a failed or overdue backup.
|
||
- CI: unit tests on PHP 8.2–8.4, and an end-to-end backup→restore round trip on Nextcloud 32–35 ×
|
||
SQLite/MariaDB/PostgreSQL, and against real S3 and SFTP backends (not just a local path).
|
||
|
||
### Known limitations
|
||
- No full/disaster-recovery restore yet (phase 2).
|
||
- No per-user backup/restore via user_migration yet (phase 2).
|
||
- No FTP/SMB coverage in CI yet, and no verification/checksum-audit command yet (phase 2).
|
||
- See the "Storage backend experiences" section of the README for provider-specific quirks found
|
||
so far (e.g. Hetzner Storage Box sub-accounts).
