📦 Backing Up Your Database

To create a complete snapshot of all profiles, accounts, posts, timelines, and scrape history:

1-Line Backup Command

docker exec -t instagram_saved_posts_mongo mongodump --db instagram --archive=/data/db/backup_$(date +%Y%m%d_%H%M%S).archive

Copying the Backup to Your Host Machine

docker cp instagram_saved_posts_mongo:/data/db/backup_latest.archive ./backup_latest.archive

---

🔄 Restoring from Backup

To restore an archive into a running container:

# 1. Copy the archive into the container
docker cp ./backup_latest.archive instagram_saved_posts_mongo:/data/db/backup_restore.archive

# 2. Restore into MongoDB
docker exec -t instagram_saved_posts_mongo mongorestore --db instagram --archive=/data/db/backup_restore.archive --drop

---

🚚 Migrating to a New Server

1. Run the backup command on your old server.
2. Transfer backup_latest.archive and docker-compose.yml to the new server via scp or rsync.
3. Run docker compose up -d on the new server.
4. Run the restore command on the new server.
5. All profiles, session cookies, and post archives will be restored seamlessly!
