In the Schedule Snapshot dialog box, configure the following settings. |
|
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. | |
|
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:
|
• |
Hours to Perform Snapshots = 8, 12, 16, 20 |
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. |
