Creating a Snapshot copy manually

Why to create a Snapshot copy manually

You might create a manual (unscheduled) Snapshot copy for the following reasons:

You anticipate planned downtime or you need to recover from downtime (during which a Snapshot copy was not taken on time).
You have just carried out a manual update of a secondary qtree, as described in Manually updating individual secondary storage system qtrees, and you want to immediately incorporate that update into the retained Snapshot copies on the secondary storage system.

How to create a Snapshot copy manually

You run this command on the SnapVault primary storage system or SnapVault secondary storage system containing the volume on which you want to create the Snapshot copy. To create a manual Snapshot copy of a volume, complete the following step.

Step	Action
1	From the primary storage system or secondary storage system, enter the following command: snapvault snap create volume_name snap_name volume_name is the name of the volume where the Snapshot copy to be created will reside. snap_name is the basename of the Snapshot copy to create. If there is already a Snapshot copy being created in the volume at the time this command is invoked, this command will be carried out after the other Snapshot copy is completed.

Step

Action

From the primary storage system or secondary storage system, enter the following command:

snapvault snap create volume_name snap_name

volume_name is the name of the volume where the Snapshot copy to be created will reside.

snap_name is the basename of the Snapshot copy to create.

If there is already a Snapshot copy being created in the volume at the time this command is invoked, this command will be carried out after the other Snapshot copy is completed.

Example

systemB> snapvault snap create vol1 sv_nightly

Result

SnapVault creates a new Snapshot copy and, based on the specified Snapshot copy basename, numbers it just as if that Snapshot copy had been created by the SnapVault schedule process. SnapVault names the new Snapshot copy sv_nightly.0, renames the older Snapshot copies, and deletes the oldest sv_nightly Snapshot copy.

Note
Unlike the snapvault snap sched -x command, the snapvault snap create command does not update the data in the secondary storage system qtree from the data in the primary storage system qtree prior to creating the new Snapshot copy. If you want to update your secondary qtrees prior to running the snapvault snap create command, use the snapvault update command as described in Manually updating individual secondary storage system qtrees.
