Berikut adalah skrip untuk memastikan bahwa snapshot semua droplet yang ada tanpa batasan jumlah droplet:

Penjelasan Perubahan:

1. Menghapus Batasan Jumlah Droplet: Menghapus logika yang memeriksa jumlah droplet terhadap nilai tetap 30.
2. Menggunakan doctl: Skrip sekarang menggunakan doctl untuk semua interaksi dengan API DigitalOcean.
3. Pengaturan Token: Token API diatur menggunakan export DIGITALOCEAN_ACCESS_TOKEN=$API_TOKEN.
4. Perintah doctl: Digunakan untuk mengambil ID droplet, menghapus snapshot, dan membuat snapshot.

Membuat Crontab

Untuk menjalankan skrip ini setiap hari dan menyimpan log hasilnya, ikuti langkah-langkah berikut:

1. Simpan skrip di atas ke dalam file, misalnya backup_droplets.sh.
2. Berikan izin eksekusi pada file skrip: chmod +x /path/to/backup_droplets.sh
3. Edit crontab untuk user yang sesuai: crontab -e
4. Tambahkan baris berikut ke dalam file crontab untuk menjalankan skrip setiap hari pada jam 2 pagi dan menyimpan log hasilnya ke file log yang telah ditentukan:
   bash 0 2 * * * /path/to/backup_droplets.sh >> /path/to/your/logfile.log 2>&1

Ganti /path/to/backup_droplets.sh dengan path lengkap ke file skrip Anda dan /path/to/your/logfile.log dengan path lengkap ke file log yang Anda inginkan.

Sekarang, skrip akan dijalankan setiap hari pada jam 2 pagi dan hasilnya akan dicatat di file log yang ditentukan.
