# Changelog # Changelog
## 2026-09-29
- **Separated Restic backup repositories per host**:
- Updated `services.restic.backups.default.repository` in `platforms/nixos/modules/nmasur/presets/services/restic/restic.nix` to append `/${config.networking.hostName}`, isolating backups by host in S3 (e.g., `.../restic/flame` and `.../restic/swan`).
- Enabled `services.restic.backups.default.initialize = true` to automatically initialize the repository in S3 if it does not already exist.
- Resolves exclusive lock contention during post-backup `forget --prune` when multiple servers run scheduled backups in overlapping windows.
## 2026-09-19 ## 2026-09-19
