NDMP 备份

问题

  • 当 NDMP 服务器调用 Dump 执行备份时、会创建一个 "snapshot_for _backup"
  • snapshot_for _backup 是一个一致性快照,在转储完成或中止之前,该快照将保持原位
  • snapshot_for _backup 会被转储锁定,并且在转储完成或中止之前将保持锁定状态
  • 在正常操作中、在转储通知 NDMP 已完成或已中止后、 snapshot_for _backup 将被删除
  • 在极少数情况下, NDMP 服务器无法再与转储通信
  • 当 NDMP 服务器与其关联的转储会话失去连接时、尝试删除 snapshot_for _backup 会生成以下错误:

Error: Snapshot copy [snapshot name] of volume [vol name] on Vserver [vserver name] has not expired or is locked.

  • 输出vol snapshot show表示 "busy" true 和 "Owners " 转储:

::> vol snapshot show -vserver [vserver name] -volume [vol name] -snapshot snapshot* -fields create-time,owners,busy
vserver    volume snapshot                 create-time              busy owners
