Bacula Heartbeat Interval

Bacula 是一套開放源始碼集中備分系統，bacula-dir負責呼叫bacula-fd進行備分，bacula-fd將備分資料傳給bacula-sd後寫入備分媒體。以上是三個主要的組件，其它的附屬工具還有bconsole、bacula-web、bscan、bcopy、、等
值得一提的是bacula提供的windows版備分用戶端還支援VSS功能，因此可以線上備分資料庫檔案，不會因為檔案使用中而備分失敗。

Heartbeat  Interval參數設定是為了避免備分的檔案過多或過大，因備分時間過長造成網路連線被中斷而設的參數。如果檔案可以正常備分但是備分到一半會忽然停住，可能就要在上面三個主要組件加入這個參數。
