例 1.顯示使用 DD OS 5.0 及更新版本的快照。
# snapshot list mtree /data/col1/ddmtree1 Snapshot Information for MTree: /data/col1/ddmtree1 ---------------------------------------------------------------------- Name Pre-Comp (GiB) Create Date Retain Until Status -------- ------------- --------------- ------------ ------ new-snap1 0.0 July 12 2010 11:59 July 12 2010 12:04 expired Snapshot Summary ------------------- Total: 1 Not expired: 0 Expired: 1
命令輸出顯示:
- 快照名稱
- 快照中的預壓縮資料量
- 建立日期
- 保留日期
- 狀態(狀態為空白或已過期)
例 2.
顯示(或列出)所有快照計劃。
# snapshot show schedule Snapshots are scheduled to run "daily" at "0700". Snapshots are scheduled to run "daily" at "1900". Snapshots are retained for "60" days.
例 3.
Creating snapshot schedules. Snapshot schedules can be configured with any of the three following commands: snapshot schedule create <schedule-name> [mtrees <mtree-list>] [days <days>] time <time>-<time> [every <hrs | mins> snapshot schedule create <schedule-name> [mtrees <mtree-list>] [days <days>] time <time> [,<time> ...] [retention <period>] [snap-name-pattern <pattern>] snapshot schedule create <schedule-name> [mtrees <mtree-list>] [days <days>] time <time> every <mins> [retention <period>] [snap-name-pattern <pattern>] The above commands will create a snapshot schedule with the name of <schedule-name> that will create a snapshot of <mtree-list> during the days specified.
範例輸出:
快照排程建立 sched3 MTrees/data/col1/備份時間 06:00 每 30 分鐘一次
- 排程 sched3 將建立下列項目的快照: /data/col1/backup 在早上 6:00,之後每 30 分鐘繼續另一個快照。
- 如果需要將其他 mtree 新增至已定義的特定快照排程,請使用快照排程 add:snapshot schedule add <name> mtree <mtree-list>
(這會將多個 MTree 新增至單一快照排程)。
