Managing snapshots

Scheduling snapshot generation

1
Start the Backup Job Wizard, and click Create New next to the Selections list.
6
Select the Volumes node, and in the Actions list, click Auto-Schedule.
7
In the Schedule Snapshot dialog box, configure the following settings.

Number of weekly snapshots

Weekly Snapshots are taken each Sunday at 12:00 midnight. This setting indicates how many snapshots are to be taken each week at this time before replacing (overwriting) the first one.

Number of daily snapshots

Daily Snapshots are taken each night at 12:00 midnight. This setting indicates how many snapshots are to be taken each night at this time before replacing (overwriting) the first one.

Number of hourly snapshots

This setting indicates, based on the values specified in the Hours to Perform Snapshots box, how many snapshots are to be taken before overwriting the first one.

Hours to perform snapshot

This setting specifies the hours at which the snapshot is generated. For example, to generate the snapshot at 7:00 A.M., enter 7. To specify multiple values, separate the values by a comma (,). Ensure that the values are specified in ascending order (for example, 8, 10, 18, 20).

A zero (0) value set in any of these boxes results in no Snapshot of that type being performed.

For this example, the following values were specified in the Schedule Snapshot window:

As a result the following would occur:

Hourly Snapshots: The first snapshot is taken at 8:00 A.M., followed by one at 12:00 noon, a third at 4:00 P.M., and the fourth at 8:00 P.M. Subsequently, the fifth snapshot is taken at 8:00 A.M. the following day followed by the sixth and final snapshot at 12:00 pm. The cycle restarts with Snapshot #1, but the time sequence specified in the Hours to Perform Snapshot box is maintained. Therefore, NetVault Backup prompts the filer to generate six snapshots starting with first at 4:00 P.M. Being the first of the series of six, this one overwrites the original snapshot taken the first day at 8:00 A.M. The second snapshot is taken at 8:00 P.M., and replaces the initial second snapshot taken at 12:00 noon, and so on.
Daily Snapshots: This Snapshot is taken at 12:00 midnight. This snapshot is separate from the ones taken hourly, unless “0” (Midnight) is set in the Hours to Perform Snapshots box. In this case, this Snapshot would take its place. A second Daily Snapshot is taken the following night at the same time. On the third night, the next Snapshot will be taken at midnight, but this one will overwrite the one taken the first night. This process continues to occur each night, with the new Snapshot overwriting the oldest.
Weekly Snapshot: Snapshots set in this field would be taken weekly at 12:00 midnight. These snapshots are separate from other Snapshots except a Daily Snapshot on a Sunday night — this Snapshot would take its place. Since this parameter is set to zero (0) in this example, no Snapshots are taken weekly.

Reserving disk space for snapshots

2
Select the Volumes node, and in the Actions list, click Reserve.
3
In the Reserve dialog box, configure the following settings.

Current percentage reserved for snapshots

This setting displays the percentage of disk space reserved for snapshots currently. The default value is 20%.

Current space reserved for snapshots:

This setting displays the physical amount of space reserved for snapshots in relation to the percentage setting. For example, if 20% of a 10 GB drive is set, this value would read 2.0 Gbytes

New Percentage to reserve for snapshots

This setting allows you to modify the percentage of disk space reserved for snapshots.
