use_vss

--use_vss={auto|software_auto|acronis|native|software|hardware|none}

Volume Shadow Copy Service (VSS) notifies VSS-aware applications that the backup is about to start. This ensures the consistent state of all data being used by such applications. Then, VSS tells a snapshot provider to create the snapshot. You can select the snapshot provider that VSS will use for taking snapshots.

Available values of the parameter are as follows:

• auto (by default)

  VSS will use the hardware-based provider that supports the source volume. If none is found, VSS will use the Microsoft Software Shadow Copy provider.

• software_auto

  In most cases, VSS will use the Microsoft Software Shadow Copy provider.

• acronis

  VSS will use Acronis VSS Provider for taking snapshots.

• native

  VSS will use the system provider (Microsoft Software Shadow Copy provider) for taking snapshots.

• software

  VSS will use any available software-based provider that supports the source volume.

• hardware

  VSS will use the hardware-based provider that supports the source volume. If no hardware-based provider is found, snapshots will be created by means of Acronis Backup & Recovery 11.5.

• none

  Choose this value if your database is incompatible with VSS. Snapshots will be created by means of Acronis Backup & Recovery 11.5. Snapshots are taken faster but data consistency of the applications whose transactions are not completed cannot be guaranteed.
