52 Provisioning the system
Creating multiple snapshots
You can select multiple volumes and immediately create a snapshot of each volume.
To create multiple snapshots
1. In the Configuration View panel, right-click the system or Vdisks or a vdisk and then select Provisioning
> Create Snapshots .
2. In the main panel, select each volume to take a snapshot of. To select or clear all volumes, toggle the
checkbox in the heading row.
3. Click Create Snapshots . If the task succeeds, the snapshots appear in the Configuration View panel.
Creating a snapshot
You can create a snapshot now or schedule the snapshot task.
NOTE: The first time a snapshot is created of a standard volume, the volume is converted to a master
volume and a snap pool is created in the volume’s vdisk. The snap pool's size is 20% of the volume size or
10 GB, whichever is larger. Before creating or scheduling snapshots, verify that the vdisk has enough free
space to contain the snap pool.
To create a snapshot now
1.
In the Configuration View panel, right-click a volume and select
Provisioning > Create Snapshot
.
2. In the main panel, select Now .
3.
Optionally change the default name for the snapshot. A snapshot name is case sensitive and cannot
already exist in a vdisk. A name cannot include a comma, double quote, or backslash.
4. Click Create Snapshot . If the task succeeds, the snapshot appears in the Configuration View panel.
To schedule a create snapshot task
1. In the Configuration View panel, right-click a volume and select Provisioning > Create Snapshot .
2.
In the main panel, select
Scheduled
.
3. Set the options:
• Snapshot prefix. Optionally change the default prefix to identify snapshots created by this task. The
prefix is case sensitive and cannot include a comma, double quote, or backslash. Automatically
created snapshots are named prefix _s001 through prefix _s1023.
• Snapshots to Retain. Select the number of snapshots to retain. When the task runs, the retention
count is compared with the number of existing snapshots:
• If the retention count has not been reached, the snapshot is created.
• If the retention count has been reached, the volume's oldest snapshot is unmapped, reset, and
renamed to the next name in the sequence.
• Start Schedule. Specify a date and a time in the future for the schedule to start running.
• Date must use the format yyyy - mm - dd .
• Time must use the format hh : mm followed by either AM, PM, or 24H (24-hour clock). For
example, 13:00 24H is the same as 1:00 PM.
• Recurrence. Specify how often the task should run. It is not recommended to set the interval to less
than two minutes.
• Time Constraint. Specify a time range within which the task should run.
• Date Constraint. Specify days when the task should run.
• End Schedule. Specify when the task should stop running.
4. Click Schedule Snapshots . If processing succeeds, the schedule is saved and can be viewed in the
overview panel for the volume or system.
