You can also use the controls at the bottom of the table to navigate to a specific page or change the number of rows for each page.

To Find a Specific Snapshot

In Qumulo Core version 4.3.3 (and higher), you can search for a specific snapshot by name, creation time, and so on.

Managing Snapshots by Using the qq CLI

This section explains how to create snapshots on a schedule, create a snapshot with an expiration time, and modify a snapshot’s expiration time by using the qq CLI.

Creating Snapshots on a Schedule by Using a Snapshot Policy

Use the qq snapshot_create_policy command to create a snapshot policy and specify the interval at which Qumulo Core takes and deletes snapshots.

In the following example, we create a policy named every_day that takes a snapshot every midnight in the Pacific time zone and retains the snapshot for two days. Every new snapshot that this policy creates is locked with a key named my-key-name. For more information, see Locking and Unlocking Snapshots in Qumulo Core.

Use the qq snapshot_create_policy command to create a snapshot policy and specify the interval at which Qumulo Core takes and deletes snapshots.

In the following example, we create a policy named every_day that takes a snapshot every midnight in the Pacific time zone and retains the snapshot for two days. Every new snapshot that this policy creates is locked with a key named my-key-name. For more information, see Locking and Unlocking Snapshots in Qumulo Core.

Creating an On-Demand Snapshot with an Expiration Time

Use the qq snapshot_create_policy command to create a snapshot policy and specify the interval at which Qumulo Core takes and deletes snapshots.

In the following example, the snapshot expires on December 31, 2030, at midnight, in UTC time.

In the following example, Qumulo Core deletes the snapshot in one year from the snapshot’s creation time.

Modifying a Snapshot’s Expiration Time

Use the qq snapshot_modify_snapshot command and specify the snapshot ID from the Saved Snapshots page in the Web UI (for example, for the 1234567_replication_from_prod snapshot, the ID is 1234567).

In the following example, the snapshot with ID 1234567 never expires.

In the following example, the snapshot with ID 1234567 never expires.
