3.19.1
Set Snapshot
This function creates a Snapshot destination SDV for a NAS user volume and sets an acquisition schedule.
This function is displayed in a Unified Storage environment.
Initial Snapshot setting (*1)
•
SDVs are automatically created in proportion to the specified number of generations.
•
The logical capacity of SDVs is the same as the NAS user volumes. (*2)
•
The base name for SDVs can be specified.
•
The RAID group to store SDVs can be selected. (*3)
•
When the Snapshot setting successfully completes, a Snapshot is automatically acquired.
*1:
"Initial Snapshot setting" is when the Snapshot is first configured from a non-configured state, or the first time a
configuration is performed after the [Delete Snapshot] function has been executed.
*2:
SDVs in proportion to the specified number of generations all have the same capacity.
*3:
SDVs in proportion to the specified number of generations are stored in the selected RAID group.
Snapshot setting modification
•
The number of generations can be changed.
•
The acquisition schedule (day of the week and time) can be changed.
•
When increasing the number of generations, unused SDVs are automatically created.
•
When reducing the number of generations, SDVs are deleted from the unused SDVs first, and then older
generation SDVs.
•
When the Snapshot is "Active", the Snapshot start state is continued.
The ETERNUS DX60 S3, the ETERNUS DX8700 S3/DX8900 S3, and the ETERNUS DX200F do not support the
