### ⚠️ Database backups
Your packet data lives in `/app/data/meshcore.db` (a SQLite file inside the `meshcore-data` Docker volume). If the volume is deleted, all data is gone.
Your packet data lives in `meshcore.db` inside the `meshcore-data` Docker volume. If the volume is deleted, all data is gone.
**Backup regularly:**
**Find your database file:**
```bash
# Copy the database out of the container
docker cp meshcore-analyzer:/app/data/meshcore.db ./meshcore-backup-$(date +%Y%m%d).db
# Show where Docker stores the volume on disk
docker volume inspect meshcore-data --format '{{ .Mountpoint }}'
# e.g., /var/lib/docker/volumes/meshcore-data/_data/meshcore.db
```
**Back it up:**
```bash
# Copy the DB to a backup location
cp $(docker volume inspect meshcore-data --format '{{ .Mountpoint }}')/meshcore.db ~/meshcore-backup-$(date +%Y%m%d).db
```
**Automate with cron (recommended):**
```bash
# Add to crontab: daily backup at 3am
0 3 * * * docker cp meshcore-analyzer:/app/data/meshcore.db /home/youruser/backups/meshcore-$(date +\%Y\%m\%d).db
0 3 * * * cp $(docker volume inspect meshcore-data --format '\{\{ .Mountpoint \}\}')/meshcore.db /home/youruser/backups/meshcore-$(date +\%Y\%m\%d).db
```
Keep at least 7 days of backups. SQLite files are portable — you can copy them to another machine and restore by simply placing the file back.
**Tip:** If you'd rather mount a local directory instead of a Docker volume (easier to find and back up), replace `-v meshcore-data:/app/data` with `-v ./analyzer-data:/app/data` in the docker run command.
