Delete the TIB file and backup after the command is executed despite command execution failure or success. temporary files and fail the task if the command execution fails. Continue the backup concurrently with the command execution and irrespective of the command execution result. 3.3.1.4 Multi-volume snapshot This option is effective only for Windows operating systems. This option applies to disk-level backup. The option determines whether to take snapshots of multiple volumes at the same time or one by one. The preset is: Enable. When this option is set to Enable, snapshots of all volumes being backed up will be created simultaneously. Use this option to create a time-consistent backup of data spanned across multiple volumes, for instance for an Oracle database. When this option is set to Disable, the volumes' snapshots will be taken one after the other. As a result, if the data spans across several volumes, the resulting backup may be not consistent. 3.3.1.5 Volume Shadow Copy Service This option is effective only for Windows operating systems. The option defines whether a Volume Shadow Copy Service (VSS) provider-either Acronis VSS or Microsoft VSS-has to notify VSS-aware applications that the backup is about to start. This ensures the consistent state of all data used by the applications, in particular, completion of all database transactions, at the moment of taking the data snapshot by Acronis Backup & Recovery Server OEM.
