### **📌 How to Use**

#### **1️⃣ Create the Directory List File**

Example: `/opt/AZURE/dir2sync_list`

```plaintext
/opt/AZURE/BLOB > testcontainer115
/opt/AZURE/OTHERBLOB > testcontainer115b
/opt/AZURE/EXTRABLOB > testcontainer_extra
```

---

#### **2️⃣ Run the Script**

```bash
./run_azcopy.sh /opt/AZURE/dir2sync_list true 20
```

- `true` → Enables logging.  
- `20` → Limits bandwidth to **20 Mbps**.  

---

#### **3️⃣ Cron Job (Runs Every Hour)**
```bash
0 * * * * /opt/AZURE/run_azcopy.sh /opt/AZURE/dir2sync_list true 20
```

### **✅ Key Features**
✅ **Prevents multiple instances** using a lock file (`/tmp/run_azcopy.lock`).  
✅ **Reads a file with directory-to-container mappings.**  
✅ **Validates each source directory before syncing.**  
✅ **Checks if the destination container exists** (test write).  
✅ **Stops immediately on any error** (clean runs only).  
✅ **Monitors `azcopy` every 30 seconds** and stops if business hours begin.  
✅ **Processes all directories sequentially using an array (fixing loop issue).**  
✅ **Uses one log file for the entire run.**
