Creating Synchronized Snapshots
The vxsnap create command creates snapshots of all volumes in the Exchange storage group or the SQL database components on the Primary and Secondary hosts, at the same point of data consistency. You can specify a name of your choice for the xml file that stores the snapshot metadata. If nothing is specified, then the snapshot is named according to a default naming convention.
Warning: |
If you have created the RVG on the Primary and Secondary using the vxrvg command and created the RLINKs using the vxrlink command, then you must ensure that the RVG, disk group names, and volume names are the same before creating the RLINK. Having different component names can cause the snapshot command to fail. |
Note: |
Separate the source volumes and attributes with forward slashes, not spaces. Source and snapshot volume attributes are paired. You must specify the source volume if you choose to specify the snapshot volume plex, drive letter, drive path, label, or volume name. |

Parameter

Description |
|
-x <Filename>
|
Indicates the name to be assigned to the XML metadata file that the vxsnap create command creates. The file name must include the ".xml" extension. By default, the file is stored at: C:\Documents and Settings\All Users\Application Data\Veritas\VxSnapExchangeBackup
If you want to place the file in another directory, specify a full path before the file name, for example J:\XML\Image1.xml.
|
|
-E
|
Runs the Eseutil consistency check for the Exchange database and log files. Eseutil is run automatically with a full backup, but must be optionally specified for a copy backup.
|
|
-o
|
Allows an existing XML file of the same name to be overwritten. If -O is not specified the vxsnap create command does not overwrite an existing XML file of the same name and the operation fails.
