The steps are simple and we have mentioned this solution which is the same as the above Volume Shadow Copy Service errors. Thus, here we won't repeat it. SFC tool can help you to scan system files, and replace incorrect versions of the system files with the correct versions. To perform a system file check can be helpful to fix Shadow Copy Service error 0x How to fix the issue SFC scannow not working?

Here, this article focuses on two cases of SFC error. Try to use the following methods. In addition to the Volume Shadow Copy service used by system restore is not working error, sometimes you fail to restore the system with the error message " System Restore does not appear to be functioning correctly on this system.

A Volume Shadow Copy Service component encountered an unexpected error When encountering system image restore failed volume shadow copy service issue, you can still fix it. If the 0x error is triggered when opening the System Restore utility, it can be fixed by a clean boot.

Follow these steps:. Step 2: Under the General tab, uncheck the Load startup items from the Selective startup menu. In this part, we have shown you four VSS errors which happen when you are creating a system image or performing a system restore with the Windows built-in backup and restore utility.

By following the corresponding solution, probably you can fix it. Click to tweet. But recently some of you turn to us for help, saying " is there anyone alternative to Windows Backup and Restore so as to effectively create a system image and restore the image ". The answer is yes. Here, we will show you one free backup software from MiniTool Solution Ltd.

As an excellent backup solution, this freeware lets you not only create scheduled backups by setting the specific time point but also set incremental and differential backups for the only changed or newly added data. In the event of system accidents, the image file is available to restore the system to its previous state with simple clicks.

Now, get the Trial Edition of this backup software for days free trial. Step 1: After completing the installation of this tool on your computer, open it to the main interface. Step 2: It's the time to choose the partitions you want to backup and decide the location you want to save the image to. Just enter the Backup tab, and you can view this free backup software has checked the drives required for Windows to run.

If you need to create a system disk image, enter the Source section to select all system partitions. Usually, we choose to create image files on the external drive. Step 3: Go back to the Backup interface, and click Back up Now button finally. In this phase, the requestor can move the data to a backup media, if needed.

Interactions in this stage are between the requestor and the VSS framework. The SQL writer is not involved. This is also the time at which the SQL writer can commit the backup as a differential base, if the current backup is a full backup of the database and not a copy-only backup.

The requestor should send this event Backup Complete event explicitly to allow the SQL writer to commit differential base backups. If this event is not received, the backup that is created will not be an eligible "differential base" backup. The requestor should save the Backup Component Document and each component backup metadata along with the data backed from the snapshot.

The only extension of the component set structure in SQL Server is the introduction of full-text catalogs. Full-text catalogs are container directories, which cannot be expressed as the VSS database or log files, given that the VSS database and log files do not have recursive specification. The snapshot creation phase is fast less than 60 seconds , to prevent blocking of all writes to the database.

Post-snapshot If autorecovery is needed for the snapshot, the SQL writer will do the autorecovery for each database that has been selected to be in the snapshot. For a detailed explanation, see Auto-Recovered Snapshots.

The following figure shows the dataflow diagram during a VSS restore operation. To more fully understand the basic tasks involved in performing a restore, it is useful to break down this overview into the following topics:. Between these two phases, the backup application is responsible for moving the relevant data around underneath SQL. During the initialization phase of a restore, the requestor needs to have access to the stored Backup Components Documents.

The Backup Component Document that is generated during the backup operation, is stored as part of the backup data. The backup application needs to pass this data back to the VSS framework.

The SQL writer obtains access to this data at the beginning of the restore process. In preparing for a restore, a requestor uses the stored Backup Components Document to determine what is to be restored and how. The requestor will select the components to be restored and set appropriate restore options as needed. If a backup application intends to apply differential or log backups on top of the current restore operation i. The SQL writer will examine the supplied Backup Component Document to identify the appropriate databases, deleting any additional files created since the backup time.

It also checks disk spaces and closes any opened database file handles so that the requestor can copy the needed data during the Restore phase. This phase allows any early error conditions to be detected before the requestor does the actual file copying.

SQL Server will also put the database in restoring state. From this point on, the database cannot be started until a successful restore. This is purely a requestor-specific action. It is the responsibility of the requestor backup application to copy the needed database files or copy relevant ranges of data for differential restores to the appropriate places.

The SQL writer is not involved in this operation. Once all the data is restored to the right places, a call from a requestor notifying that the restore operation has been completed IvssBackupComponents::PostRestore , will let the SQL writer know that Post Restore actions can be started. The SQL writer at this point will do the Redo phase of crash recovery. If recovery is not requested that is, SetAdditionalRestores true is not specified by the requestor , the undo phase of the recovery step is also carried out during this phase.

The SQL writer could be involved in the volume shadow copy creation process outside the context of backup and restore because the db files' backing volume s have been added into the volume snapshot set. The SQL writer supports full backup and restore operations in both noncomponent-based mode and component-based mode.

In a noncomponent-based backup and restore, the requestor specifies a volume or a folder tree to be backed up and restored. All the data in the specified volume and folder is backed up and restored.

In a noncomponent-based backup, the SQL writer implicitly selects databases by using the list of volumes in the snapshot set. The writer checks for torn databases, raising an error if found. Roll forward differential or log restores after a restore is not supported through the SQL writer. The requestor restores database s that have been backed up in noncomponent-based mode.

Such restores cannot be followed up by a rollforward restore, such as log restore or differential restore. The files are copied in place and then the database s attached. All this happens outside the scope of the SQL writer. In a component-based backup, all backing volumes for selected databases should be included in the volume snapshot set.

Otherwise, the SQL writer will detect torn databases with backing volumes outside the snapshot set and fail the backup. A full backup backs up database data and all the log files necessary to bring the database up to a transactionally consistent state at restore time. A full restore of the database backup is sometimes accomplished without doing any additional roll forwards.

This may be because there is no metadata to facilitate the rollforward or, in some cases, roll forwards are not needed. This section covers these two situations briefly. The requestor restores database s that have been backed up in component-based mode but no roll forwards are requested.

In this case SQL Server will perform crash recovery on the database as part of restore. The requestor can issue a restore specifying the SetAdditionalRestores true option. This option indicates that the requestor is going to follow up with more rollforward restores such as log restore, differential restore etc. This instructs SQL Server not to perform the recovery step at the end of the restore operation.

This is only possible if the writer metadata was saved during the backup and is available to the SQL writer at the time of the restore. The SQL writer reports full-text catalog containers with recursive file specifications under the database components in the Writer Metadata Document. They are automatically included in the backup when the database component is selected. A differential backup operation backs up only the data that has changed since the most recent base full backup.

A differential backup contains only those parts of the database files that have changed. In order to do such a backup, the backup application, or requestor would need information about the location of the changes in the database files, so that appropriate sections of the file s can be backed up. During a differential backup operation, the SQL writer provides this information in the format as specified by "VSS partial file information. This partial file information allows the requestor to choose only changed byte-ranges to back up for the database files.

During the Pre Backup Tasks phase, the SQL writer will make sure that a single differential base for each selected database exists. The SQL writer supports only a single differential baseline for differential backups.

Multi-baselines are not supported. For each database being backed up during a differential backup, the SQL writer will store the partial file information for each database file. This information is used by the requestor or backup application to copy only relevant portions of the file to the backup medium during the actual backup of the files. For more information on the format for this partial file information, see the documentation for Volume Shadow Copy Service.

IVssComponent::GetPartialFile will return a path and a filename pointing to the file, and a ranges string indicating what needs to be backed up in the file. For more information of the partial file information retrieval, see the VSS documentation. During this phase, the backup application should look at the writer metadata stored in the Backup Component Document and back up only the relevant portions of the files. For full-text catalog files, this backup should be done based on the file timestamps.

This is described later in this document. A differential backup will always be with respect to the latest base backup that exists for the database. At restore time, SQL Server will detect mismatched base and differential backups. So, it is responsibility of the backup application or system administrator to be sure that the differential is relative to the expected full backup.

If some out of band procedure has made another full backup, the backup application may not be able to restore the differential, since it doesn't "own" the base backup.

Currently if the byte-range information partial file information is too large exceeding 64 K bytes in buffer size , SQL Server will throw an error instructing the user to perform a full backup. These files are included in the partial specification because every header of the SQL database file needs to be in the partial specification. Besides the header page, all the allocated pages need to be included in the partial specification.
