# Synology DS218plus
|
|
|
|
Operational notes for accessing and navigating the Synology NAS without rediscovering paths.
|
|
|
|
## Connection
|
|
|
|
- SSH config alias: `synology`
|
|
- Hostname/IP: `192.168.86.31`
|
|
- SSH user: `jared`
|
|
- SSH key from `~/.ssh/config`: `~/.ssh/id_ed25519_git`
|
|
- Verified NAS hostname: `DS218plus`
|
|
|
|
Quick check:
|
|
|
|
```bash
|
|
ssh synology 'hostname; id'
|
|
```
|
|
|
|
Expected identity:
|
|
|
|
```text
|
|
DS218plus
|
|
uid=1026(jared) gid=100(users) groups=100(users),101(administrators),65536(family)
|
|
```
|
|
|
|
## Volume Paths
|
|
|
|
Synology shared folders are mounted under `/volume1` over SSH.
|
|
|
|
Important paths:
|
|
|
|
| Purpose | SSH path |
|
|
| --- | --- |
|
|
| Main backup share | `/volume1/backup` |
|
|
| Fedora continuous restic repo | `/volume1/backup/fedora_desktop_backup_continuous` |
|
|
| Older May 2024 user backup | `/volume1/backup/jared_backup052124` |
|
|
| Older May 2024 Fedora backup | `/volume1/backup/fedora_backup052124` |
|
|
| October 2024 Fedora recovery folder | `/volume1/backup/fedora_recovery_oct2024` |
|
|
|
|
List likely backup folders:
|
|
|
|
```bash
|
|
ssh synology 'find /volume1/backup -maxdepth 2 -mindepth 1 -type d | sort'
|
|
```
|
|
|
|
## Restic Access
|
|
|
|
Local `restic` is installed at `/usr/bin/restic`. Credentials are sourced from `~/.credentials`; do not print the file or password.
|
|
|
|
The active backup script uses:
|
|
|
|
```bash
|
|
source ~/.credentials
|
|
restic -r "sftp:${SYNOLOGY_HOST}:${SYNOLOGY_PATH}" snapshots --compact
|
|
```
|
|
|
|
As of 2026-05-14, `~/.credentials` has:
|
|
|
|
```text
|
|
SYNOLOGY_HOST=synology
|
|
SYNOLOGY_PATH=/home/Backups/fedora-workstation
|
|
```
|
|
|
|
Note: that SFTP path is a virtual path for restic/SFTP access. Over an interactive SSH shell, the same repository is visible at:
|
|
|
|
```text
|
|
/volume1/backup/fedora_desktop_backup_continuous
|
|
```
|
|
|
|
Repository structure confirmed on 2026-05-14:
|
|
|
|
```text

|

|
|

|
|

|

|

|
|
snapshots/
|
|
```
|
|
|
|
## Useful Restic Commands
|
|
|
|
List snapshots:
|
|
|
|
```bash
|
|
source ~/.credentials
|
|
restic -r "sftp:${SYNOLOGY_HOST}:${SYNOLOGY_PATH}" snapshots --compact
|
|
```
|
|
|
|
List a path in the latest snapshot:
|
|
|
|
```bash
|
|
source ~/.credentials
|
|
restic -r "sftp:${SYNOLOGY_HOST}:${SYNOLOGY_PATH}" ls latest /home/jared/.ssh
|
|
```
|
|
|
|
Search snapshots for specific files:
|
|
|
|
```bash
|
|
source ~/.credentials
|
|
restic -r "sftp:${SYNOLOGY_HOST}:${SYNOLOGY_PATH}" find /home/jared/.ssh/id_rsa /home/jared/.ssh/id_rsa.pub
|
|
```
|
|
|
|
Restore a specific file or directory to a temporary location:
|
|
|
|
```bash
|
|
source ~/.credentials
|
|
mkdir -p /tmp/restic-restore
|
|
restic -r "sftp:${SYNOLOGY_HOST}:${SYNOLOGY_PATH}" restore latest \
|
|
--target /tmp/restic-restore \
|
|
--include /home/jared/path/to/file
|
|
```
|
|
|
|
## Snapshot State on 2026-05-14
|
|
|
|
The Fedora continuous repo is accessible and decrypts successfully. It had 17 snapshots from 2026-04-11 through 2026-05-11.
|
|
|
|
Latest snapshot observed:
|
|
|
|
```text

## SSH Key Recovery Findings
|
|
|
|
Checked while investigating Hyperthrive VPS access on 2026-05-14:
|
|
|
|
- Latest restic snapshot `.ssh` contains only `config`, `id_ed25519_git`, `id_ed25519_git.pub`, `id_ed25519_ovh_backup`, `id_ed25519_ovh_backup.pub`, `known_hosts`, and `known_hosts.old`.
|
|
- `restic find` did not find `/home/jared/.ssh/id_rsa`, `/home/jared/.ssh/id_rsa.pub`, `id_ed25519_forgejo`, or `id_ed25519_forgejo.pub`.
|
|
- `/volume1/backup/jared_backup052124/.ssh` exists but is empty.
|
|
- `/volume1/backup/fedora_backup052124/jared/.ssh` exists but is empty.
|
|
- No `.ssh` files were found under `/volume1/backup/fedora_backup052124` or `/volume1/backup/fedora_recovery_oct2024` in the checked paths.
