4.3.12. 備份卷冊群組的 Metadata
Metadata 備份和 archive 會在每個卷冊群組和邏輯卷冊配置遭到變更時被自動地建立，除非您在
lvm.conf 檔案中將它停用。就預設值，metadata 備份儲存在 /etc/lvm/backup 檔案中，並且 metadata archive 則儲存在 /etc/lvm/archives 檔案中。您可透過 vgcfgbackup 指令來手動式地將 metadata 備份至 /etc/lvm/backup 檔案中。
vgcfrestore 指令會將卷冊群組的 metadata 由 archive 復原至卷冊群組中所有的實體卷冊中。
欲取得使用
vgcfgrestore 指令來復原實體卷冊 metadata 上的相關範例，請參閱〈節 6.4, “復原實體卷冊的 Metadata”〉。
