Testing the EMC TimeFinder Snap backup
After you complete the Symmetrix configuration steps as described in this chapter and run a backup, you can verify that the snapshot was successful.
To test the EMC TimeFinder Snap backup
- Enter the following command to verify that the snapshot was successful.
symsnap -g nbfim_test query -multi
The -multi option shows multiple snapshots.
For example:
C:\Program Files\EMC\SYMCLI\bin\symsnap -g dmx-5D query -multi
where dmx-5D is the name of the Symmetrix device group.
Sample output:
Device Group (DG) Name: dmx-5D
DG's Type : REGULAR
DG's Symmetrix ID : 000187910258
