Once a snapshot set has been created, it can be refreshed quickly since you do not have to prepare a mirror in order to refresh it. To refresh the snapshot set you need to perform the following tasks:
Reattach (snapback) the snapshot
This operation reattaches and resynchronizes an existing snapshot set so that it matches the current set of its original database.
You can perform this operation from either the VEA GUI, using the Enterprise Vault Snapback Wizard, or from the command line, using vxsnap reattach. See the following procedures.
Create the refreshed snapshot set using either the Enterprise Vault Snapshot Wizard or the vxsnap create command
Note: |
The Enterprise Vault Refresh option available in the VEA console from the Application object refreshes the display of the application and components. It does not refresh the snapshot set. |

To reattach an EV snapshot set from the command line
> vxsnap -x snapdata.xml reattach writer=EnterpriseVault site=site1/vsg=vsg1/vs=vs1 site=site2 /component=(Index Locations (V:)) /component="Directory DB"
This command uses the information in the XML file to reattach and resynchronize all the volumes for the vault store vs1 of site1/vsg1, "Index Locations (V:)" of site2 and "Directory DB".
The snapshot volumes remain synchronized with the original volumes until the vxsnap create command is issued.
The complete syntax for the vxsnap reattach command is:
vxsnap -x Filename [-f] [-b] reattach writer=<WriterName>[site=<SiteName> [/VSG=<VSGName>[VS=<VSName>]]] [[/]component=<ComponentName>]
