The following is a description of the procedures used to perform automated backup using the VMware script provided.
Stop business applications on target virtual machine to stop I/O of business applications
Before executing the backup script, stop business applications running on a virtual machine to be backed up to stop all I/O of business applications.
Note
It is recommended that backup be performed while the virtual machine is stopped in order to perform a backup with maximum data integrity.
When the virtual machine is not stopped, it is recommended the backup with the Quiesce guest file system option enabled (Quiesce=ON).
Execute the backup script
Execute the backup script from the command prompt on the CCM Server for each ETERNUS Disk storage system. The following is an example.
> powershell C:\Script_ETERNUS_1\exe\VMBackup.ps1 -l C:\Script_ETERNUS_1\log\backup.log
The backup script is processed in the following sequence.
Virtual machine snapshots are created using the snapshot function of the virtual machine.
The transaction volume is backed up (copied) to the backup volume using AdvancedCopy Manager CCM.
When backup is complete, the first snapshot created is deleted.
Restart business applications after backup
Restart business applications on the virtual machine after the backup script executing has been completed.
The following is an overview of backup script processing executed in step 2.

Note
The backup script retains one-time backup data alone. Performing backup makes the previous backup data invalid.
