# DRestic

Automated, encrypted, and deduplicated backups to MEGA cloud storage using restic.

## Setup

1.  Clone the repository:
```sh
git clone https://github.com/casparvitch/drestic
cd drestic
```

2.  Install dependencies (supports apt, yum, pacman, zypper):
```sh
make install-deps
```

3.  Run the setup script:
```sh
# For a personal machine (backs up /home/user)
make setup-user
# For a server (backs up /etc, /home, /root, etc.)
# make setup-system
```
    The script will prompt for your MEGA credentials and a new restic repository password. **Store the restic password safely.**

## Usage

All common operations are handled via the `Makefile`. Run `make help` for a full list.

**Check Status**
```sh
# For user scope
make status

# For system scope
make status-system
```

**Run a Backup Manually**
```sh
make backup-now
# Monitor with: journalctl --user -fu restic-backup.service
```

**List Snapshots**
```sh
make snapshots
```

**Recover Files**
The easiest method is to mount the repository.

1.  Create a mount point:
```sh
mkdir ~/restore
```

2.  Mount the backup:
    The repository path is now unique per host (e.g., `drestic_backups_my-server`). Find your exact path in `~/.config/restic/env`.
```sh
# For user scope (replace with your unique repo path)
RESTIC_PASSWORD_FILE=~/.config/restic/password restic mount ~/restore --repo rclone:backup_remote:/drestic_backups_my-server
```

3.  Browse `~/restore/snapshots/latest/` to find your files.

4.  Unmount when finished:
```sh
umount ~/restore
```

## Configuration

Configuration files are created during setup.

**Backup Paths & Exclusions**
-   **User scope:** `~/.config/restic/paths` and `~/.config/restic/excludes`
-   **System scope:** `/etc/restic/paths` and `/etc/restic/excludes`

Edit the `paths` file to change what is backed up. Edit the `excludes` file to add patterns to ignore. The default files contain a sensible starting point.

**Backup Schedule**
The schedule is managed by systemd timers. To change the daily 3 AM backup time:

1.  Edit the timer file:
    -   **User scope:** `~/.config/systemd/user/restic-backup.timer`
    -   **System scope:** `/etc/systemd/system/restic-backup.timer`

2.  Change the `OnCalendar=` line.

3.  Reload systemd:
```sh
# For user scope
systemctl --user daemon-reload && systemctl --user restart restic-backup.timer
# For system scope
sudo systemctl daemon-reload && sudo systemctl restart restic-backup.timer
```

**Notifications**
To add or update Gotify push notifications, run:
```sh
make update-gotify
```

## Troubleshooting

**Repository is locked?**
```sh
# Auto-detects scope and unlocks
make unlock-repo
```

**Connection issues?**
Verify rclone can connect to your MEGA account.
```sh
rclone ls backup_remote:
```

**Something else?**
Check the logs.
```sh
# For user scope
make logs

# For system scope
make logs-system
```
