CVMS - Cleanup VMware Snapshots

This application (licensed by the NetApp ToolChest License, found here) is intended to help users clean-up VMware snapshots left over after being taken by different backup applications.  A Windows executable and Perl script for UNIX environments are included.  The -snapname option allows users to specify a string to look for with VMware snapshots, and if discovered on the selected datastores, will delete those snapshots.  One common use could be to specify -snapname smvi_ to cleanup any leftover VMware-based snapshots created by SMVI.

 

Please use in a test environment to confirm it works for your environment before moving to production.  To test, simply create a VMware snapshot of a specific name for a VM, then use CVMS against the datastore and/or VM to find and delete the VMware snapshot.

 

Command output is below:

C:\>cvms -vcuser administrator -vcpasswd passwd -vcip 10.2.1.2 -snapname bar -ds test_ds -verbose
